Effects of Flame Retardant and Glass Fiber on the Properties of PA66
2022 / 07 / 16
Due to the needs of electronic product applications, PA66 must have certain flame retardancy and relative tracking index (CTI) properties. Also, depending on product strength requirements, it may be necessary to add glass fibers to the PA66 material. Commonly used flame retardants are nitrogen flame retardants, bromine flame retardants and red phosphorus. (1) Under normal circumstances, the flame retardant grade of pure nylon PA66 is UL94V-2, and the CTI value can reach CTI600. (2) When glass fiber is added to pure PA66 to increase the strength, the glass fiber is used as the core, which reduces the flame retardant grade of the material and becomes UL94-HB grade. (3) Using nitrogen-based flame retardant for PA66 and no glass fiber, it can reach UL94V-0, and the CTI value can reach 600V. (4) When glass fiber is used in PA66 and nitrogen-based flame retardant is added, the flame retardant performance of the material will also deteriorate and reach HB level. (5) PA66 also becomes UL94V-0 flame retardant grade when brominated flame retardant is added, and in the case of glass fiber reinforced material, it becomes UL94V-0 grade. However, the addition of bromide greatly reduces the CTI index of the material. Basically CTI175 or CTI250 grade. Low CTI limits the application of PA66. All Glow Wire 750 PA66 materials required by the industry are brominated flame retardants. Of course, the CTI value is not high. (6)
Difference between tube and pipe - 1
2022 / 07 / 15
It is generally thought that plastic tube and plastic pipe are the same thing. These words are often used interchangeably, because tubes and pipes are both long hollow cylinders. But they are actually quite different. Here we explain the difference between tube and pipe. What is a plastic tube? Plastic tube is a long hollow cylinder that is defined by its outside diameter (OD). The size of the bore, which is the hollow area in the middle of the tube, isn`t critical to the end use, whereas the OD is the most important measurement. Within this definition, plastic tube is not suitable for transporting liquids and gases or for applications involving pressure. For such applications plastic pipe is more suitable. Tubing is more commonly used for general purpose applications such as modelling, crafts, packaging, flags, conduit, display applications, and the construction of simple frames and structures. What is a plastic pipe?
Difference between tube and pipe - 2
2022 / 07 / 15
What is the difference between tubing and pipes? There is an important but often misunderstood difference between tube and pipe. The difference is essentially how the hollow cylinders are manufactured and measured. For pipes, the inside diameter (ID) matters a great deal because that determines the capacity of the pipe. Conversely, for tubes the outside diameter (OD) is more important and is usually the measurement that is the deciding factor. This leads to the question of why can't both the ID and OD be defined? The manufacturing process plays an important prole in answering this. It is possible to have a consistent bore, which is the ID. And it is possible to have a consistent OD. But during the extrusion process the wall thickness varies, and the manufacturer can either control the ID or OD. But not both, or at least not to a high precision. Pipe and tube are two words for hollow cylinders, but they are not the same. In si

PVC processing aids have played a very good role in the processing of our PVC pure resin. It can help us add auxiliary materials to improve its performance during processing. There are also some classifications about its types, let's take a look together below. First, ACR processing aid: ACR is a copolymer of methyl methacrylate and monomers such as acrylate and styrene. It can be used as both processing aids and modifiers. The important role of ACR processing aids is to promote the plasticization of PVC, shorten its plasticization time, improve the uniformity of melt plasticization and reduce the plasticization temperature. Second, light stabilization processing aids: Most PVC profile products are exposed to light and other various light. Adding a certain amount of light stabilization aids during processing according to the application environment of the product can prevent and relieve the decomposition and aging of the product and prolong the product Service life.

MBS (Methylmetharylate-Butadiene-Styrene) is a new type of polymer material synthesized under the concept of particle design. It is prepared by emulsion graft polymerization of methyl methacrylate (M), butadiene (B) and styrene (S). It has a typical core-shell structure in submicroscopic morphology. The core is a spherical rubber core with a diameter of 10 nm ~ 100 mm, and the outside is a shell composed of styrene and methyl methacrylate. Because the dissolution parameters of methyl methacrylate and polyvinyl chloride (PVC) are similar, it plays the role of interface adhesive between PVC resin and rubber particles, forms homogeneous phase in the process of processing and mixing with PVC, and gives the product excellent impact resistance. MBS / PVC is widely used in the composition of MBS / PVC molding materials and PVC sheet materials, as well as the impact resistance and tughness of MBS / PVC composite materials, which are similar to those of other types of molding materials and PVC sheet materials. According to different transparency, MBS impact modifiers can be divided into transparent MBS and non transparent MBS. When 5% - 10% MBS resin is added to PVC, the impact strength of the product can be increased by 4-15 times. At the same time, the cold resistance and processing fluidity of the product can be improved. Its refractive index is similar to that of PVC. Using MBS as PVC impact modifier will not affect the transparency of PVC. MBS is the best material to improve the impact resistance of PVC and manufacture transparent products. Almost all transparent PVC products use it as impact modifier. Generally speaking, MBS has appropriate compatibility when blending with PVC, and improves the stability of the blend system. The glass transition temperature of MBS is relatively low, so it can improve the impact resistance of PVC within a certain low temperature limit. Improving the toughness and processability of PVC

CRA impact modifier is the interpenetration network copolymer of slightly chlorinated HDPE and acrylate- - -CRA resin, which overcomes the weakness of high vitrification temperature and poor dispersion of CPE, and the effect of low temperature impulse resistance modification is obvious. CRA is used in the same way as CPE. During the use process, the extruder current and torque may decrease slightly, and the amount of external lubricant must be reduced until the current and torque of ACM are the same or slightly higher as that of CPE. Performance comparison of CRA traditional acrylate resistance.The low-temperature impact resistance strength of the new refractory modifying agent CRA is higher than that of the traditional CPE, the fracture elongation rate is also higher than that of CPE, and the Visa softening point is lower than that of CPE.Therefore, we can believe that the new impulse modifier modified PVC products have good low temperature impact resistance strength, excellent room temperature toughness, and excellent thermal stability and ultraviolet resistance, the new impulse modifier is an ideal PVC impulse resilience.

[Summary]: A PVC foaming regulator is actually an acrylic resin based processing aid that has all the basic functions of a PVC processing aid, with the difference compared to conventional processing aids. PVC foaming regulator has higher molecular weight and higher viscosity As a common product, PVC foaming regulator, how much do you know about its basic knowledge? Let's take a look at the basic knowledge of PVC foaming regulators. 1. The chemical composition of PVC foaming regulator. A PVC foaming regulator is actually an acrylic resin based processing aid that has all the basic functions of a PVC processing aid, with the difference compared to conventional processing aids. PVC foaming regulators have higher molecular weight and higher viscosity. 2. The main function of foaming regulator in PVC foam products. Promote the plasticization of PVC, and improve the melt strength of PVC foam materials, prevent bubble coalescence, and obtain a uniform foamed product. Preventing insufficient melt strength results in foam sheet foaming, longitudinal pimples and ensuring good melt flow for good product appearance. 3. A simple and effective method for checking melt strength. To determine whether the melt strength is insufficient, the direct method is to wrap the fingers in the middle roll of the sheet and press the three rolls back, the melt strength is good, and the elasticity can be felt when pressing. If the press is hard to bounce back, it indicates poor melt strength.
Reasons why CPE can be used as an impact modifier
2022 / 07 / 02
As an excellent impact modifier, CPE chlorinated polyethylene thermoplastic resin is used in various aspects, which can greatly improve the impact resistance of rigid PVC impact modifiers and improve processing fluidity. At the same time, CPE chlorinated polyethylene also has good chemical resistance, low temperature performance, high filling performance, excellent weather resistance and compatibility. At present, the most widely used and most economical impact modifier in the PVC pipe profile industry is CPE chlorinated polyethylene resin, which can improve impact resistance and aging properties, especially for large-diameter pressure-resistant liquid pipelines. Chlorinated polyethylene is mostly used to improve the pressure bearing capacity and increase the service life. In addition to that CPE resin acts as an impact modifier. Compatibilizers are used in flame retardant ABS, SAN, HDPE and PP to improve the impact resistance and flame retardant effect of impact modifiers.
What are the effects of ACR processing aids?
2022 / 07 / 02
ACR (Acrylic copolymer) is an acrylate copolymer with a core-shell structure, and is a PVC impact modifier with excellent comprehensive properties. Usually people call the additives used for the purpose of improving the toughness of plastics as impact modifiers, and the additives used for the purpose of improving processing properties are called processing modifiers. ACR is a plastic additive with dual functions of impact resistance modification and processing modification. Due to its core/shell structure, its PVC products have excellent impact resistance, low temperature toughness, compatibility with PVC, weather resistance, Stability, processability, and moderate performance and price ratio, can significantly improve the fluidity and thermal deformation of PVC melt, promote plasticization, and make the product surface smooth and beautiful. It is mainly used in rigid and semi-rigid PVC products, especially chemical building materials, such as profiles, pipes and fittings, plates, foam materials, etc., and is especially suitable for outdoor products. It is a type of impact modifier that is used in large quantities today and will be developed in the future. PVC is one of the plastic varieties with the largest production and consumption. It has many valuable properties, but it also has many shortcomings. Poor toughness is one of its major shortcomings. In order to improve its toughness without damaging its tensile strength and other physical properties, PVC impact modifier came into being.

Flame retardants provide an important layer of fire protection by helping to prevent or slow the spread of fire. Flame retardants inhibit or suppress the combustion process. They reduce the amount of heat released from a fire and the potential for a fire to spread. Flame retardants can also reduce the amount of smoke produced by a fire.1 The use of flame retardants is especially important today, as the large volume of electrical and electronic equipment in today`s buildings, coupled with increasingly larger volumes of combustible materials in our homes and offices, can increase the potential for fire hazards. Flame retardants can provide occupants of a home or building additional life-saving time to escape a fire, as well as time for firefighters to respond to a fire. They can also safeguard against property damage and loss associated with the fire itself or from water damage, whether from automated sprinklers or the response from local authorities.
2022 / 07 / 02
According to the National Fire Protection Association, in 2014 the total cost of fire was $328.5 billion, which was 1.9% of U.S. Gross Domestic Product (GDP). Over the years 1980 to 2014, the total cost of fire increased by 50.3%.1 Of course, preventing injury or loss of life is the most important component of fire safety, but we also need to recognize that the costs of fires go well beyond our physical well-being. Property loss can be devastating even if there are no physical victims. Photos and family heirlooms are priceless and often irreplaceable, and losing such precious items and memories associated with the home can be quite emotional. Furthermore, loss of business, retail costs, rebuilding costs, etc., can all add up to the point where a business or individual may not be able to recover, and therefore deeply impactful.

Performance advantages of ordinary PVC Wood Plastic Composites
2022 / 07 / 01
PVC Wood Plastic sheet has better tensile strength, flexural strength, flexural modulus, and impact strength compared with other sheets. The reason is that there is a strong chemical reaction ability between lignin and PVC, that is, between proton donor and acceptor. In addition, the interaction between carbonyl groups on lignin molecules and hydrogen atoms on PVC molecules or between hydroxyl functional groups on lignin molecules and chlorine atoms on PVC molecules is conducive to the improvement of mechanical properties. At present, the application of wood-based panels is mainly in the interior decoration and furniture industry. The wood-based panels used are mainly plates with urea-formaldehyde resin as the adhesive ( Such as particleboard, medium-density fiberboard, plywood, etc.). Compared with these traditional wood-based panels, wood-plastic panels mainly have the following advantages and characteristics: Firstly, Urea-formaldehyde resin is not used in the production of wood-plastic composites. There is no release of formaldehyde adhesives. This formaldehyde-free product is in line with national environmental protection policy. They are really environmentally friendly materials for human health, which is incomparable to ordinary wood-based panels.

PVC furniture board and its prospect-2
2022 / 07 / 01
The prospect of PVC furniture board At present, the PVC industry is developing rapidly all over the world with broad prospects. All countries are optimistic about the potential of PVC and its benefits to the ecological environment. PVC is proving to the world that its role and status can not be replaced by any other products with its superior and unique properties. Social development needs it and environmental protection needs it. It is the inevitable trend of the progress of human civilization. At a time when the PVC industry is booming all over the world, however, it is a pity that the market share of PVC furniture materials (including cabinets) in some countries is less than 10%. Many consumers have not even heard of PVC as a furniture material, let alone know what PVC is. When German people have treated PVC as a high-grade, non-toxic, and pollution-free environmental protection material, why market share in some countries is still so small? Of course, there is the problem of consumption level, but it is mainly related to our consumers` lack of correct understanding of PVC. It hindered the large-scale PVC furniture production. I believe that through the joint efforts of our companions and t
