The use of calcium/zinc stabiliser systems has been common in PVC applications for over 25 years. These materials are generally based on metal carboxylates and will sometimes incorporate other elements to boost performance such as aluminium or magnesium. Because the heat stability in some applications may require some enhancement when using calcium/zinc, organic co-stabilisers will also often be added to this type of formulation. These materials include polyols, epoxydised soya bean oil, antioxidants and organic phosphites.
Heat Stabilizers: The Coolest Polymer Additive
2019 / 05 / 13
Plastics are amazingly versatile and useful compounds, but they do have a common influence factor: heat. Anyone whose kid has left a toy soldier in the oven, or - if you`re old enough to remember them - had their favorite cassette tape warp in a hot car, has experienced first-hand how heat can affect plastic and vinyl materials. Heat stabilizers solve that problem by helping the materials they`re added to better resist the damage that can stem from exposure to high temperatures. These common polymer additives are precisely why extremely hot water doesn`t melt the PVC plumbing pipes in your home. When incorporated into a #polymer, heat stabilizers protect the properties of the overall compound from heat damage, either during the manufacturing process or during normal use of the finished product. While different polymers have varying degrees of heat resistance, heat stabilizers are added to virtually all polymer types. Polyvinyl chloride (PVC) is the most common polymer that benefits from a heat-stabilizing additive. Heat stabilizers help preserve the polymer`s appearance, strength, elasticity, durability and performance characteristics. Two basic types of heat stabilizers are used in polymers: organophosphites, which protect polymers during the manufacturing process, and phenolic antioxi

Common Production Methods of Chlorinated Polyethylene
2019 / 04 / 22
Chlorinated polyethylene is made of polyethylene (PE) by chlorination. It has the dual advantages of plastic and rubber. It is resistant to oil, ozone, heat and oxygen, corrosion, fire, bacteria and microorganisms. Other aspects are superior to other rubbers. It can be used alone or in combination with plastics and rubber. It has outstanding advantages in the fields of waterproofing membranes, plastic doors and windows, wire and cable sheathing, hose tape, color bicycle tires, glass door and window sealing strips, etc. An ideal polymer elastic material has broad application prospects. At present, the production process of chlorinated polyethylene CPE is divided into two categories: homogeneous chlorination process and heterogeneous chlorination process. There are three production methods according to chlorination: solvent method, aqueous phase suspension method and gas-solid phase chlorination method. The production of chlorinated polyethylene CPE should use PVC resin with loose structure and extremely thin skin layer to enlarge the surface area of PVC particles and increase the contact area with chlorine gas. In the solvent chlorination method, S-PVC is dissolved in a chlorine-containing solvent, an initiator azodiacetonitrile is added, and chlorine gas is introduced into the reaction vessel for chlorination. The carbon tetrachloride solvent method is still widely used in China, and its overall level of equipment is comparable to that of developed countries in the early 1970s. This method has a uniform reaction and is easy to process. It can be used to produce advanced corrosion-resistant coatings or used for the production of fishing nets, industrial filter cloths and other products after spinning. Disadvantages are long process flow, difficulty in solvent recovery, high production cost and easy environmental pollution. The aqueous suspension method (heterogeneous chlorination) is carried out by adding S-PVC resin to water or hydrochloric acid, stir

Flammability of microelectronic components, particularly those using molding compounds as encapsulants, is a safety concern that can be mitigated by the use of appropriate materials. In most common plastic encapsulants, flame retardant capability is acquired through the use of bromine-based aromatic compounds. These brominated flame retardants (BFRs) are preferred because of their low cost and effectiveness, especially in their ability of to ensure compliancy with industrial flammability standards. Thus, the flame retardants with aromatically bonded bromine have the highest market share, primarily because they tend to be resistant to breakdown over time or temperature. When the epoxy encapsulants are exposed to heat or open flames, the epoxy compounds break down and in the process release free radicals such as OH and H in the form of flammable gases. BFRs work by chemically interfering with the gas phase of the combustion process. However, bromine containing compounds have also been found to form dioxins during the combustion process, and these active dioxins are considered to be carcinogens by the Environmental Protection Agency (EPA). Therefore, a strong trend is emerging for selecting bromine replacement materials that is focused primarily on environmental, health, and reliability concerns. Phosphorous based flame retardants (PFRs) have been considered as alternate replacement materials to BFRs. Phosphorous based flame retardants impede the combustion process through multiple reaction steps. These PFRs are primarily divided into organic and inorganic compounds. Organic phosphorous based flame retardants currently used in electronic applications consist of phosphates, phosphonates, phosphinates, and phosphine oxides. However, the addition of organic phosphorous into molding compounds tends to increase the water absorbing property of the plastic encapsulants, increasi

Characteristics of additives used in the processing of PVC
2019 / 04 / 15
PVC processing requires the use of many additives, thanks to which it is possible to obtain products for different purposes and with different levels of flexibility.PVC is very easily modified and therefore its properties can be freely customized to very different requirements depending on the intended use.Modification is accomplished through the appropriate selection of PVC blend components.A variety of stabilizers, plasticizers, impact and flow modifiers, fillers, and other additives are used to produce PVC plastics. A feature that distinguishes PVC from other thermoplastic materials is the ability to modify its physical and mechanical properties via plasticizing, which has long been a widely used means of modification. Plasticizers are added to PVC in order to achieve the required level of flexibility of the end product.Their main task is to decrease the Tg (the glass transition temperature) of the PVC, which in turn leads to a lowering of the gelling and moulding temperature during processing.This also leads to a permanent improvement of the properties of the polymer, including its flexibility, impact resistance and resistance to low temperatures. Plasticizers can be classified based on different criteria, such as: - process characteristics (high-temperature, low-temperature plasticizers), - type of chemical (phthalat

Reasons and solutions for the precipitation of flame retardants in PP materials
2019 / 03 / 16
Flame retardant PP material is favored by more and more manufacturers because of its fine density, excellent weather resistance and low comprehensive price. It has successfully replaced flame retardant PS and flame retardant ABS in many applications. Behind the rise of flame-retardant PP materials, there may be a problem that is often encountered. That is the problem of flame retardant material precipitation, which is more obvious in halogen free flame retardants. The precipitation of flame retardants not only affects the normal production, but also affects the normal production in the process of injection molding, such as powder agglomeration, mold sticking and so on. In the finished products, it often precipitates and produces white mist like substances, which affect the appearance of products and cause the decrease of flame retardancy. Before solving the problem of flame retardants, we first discuss two important factors that affect the precipitation problem: 1. Compatibility of flame retardants with PP base resin Flame retardants are generally two states in the PP resin: the resin is filled in the form of a similar packing and the other is dispersed uniformly in the melting state. As PP is a nonpolar material, there will be a problem of interfacial compatibility between polar flame retardants and PP. The worse the interfa
