why are flame retardants still necessary?
2023 / 02 / 25
According to the National Fire Protection Association (NFPA), the number of reported fires in the United States decreased by seven percent from 2008 to 2009. In addition, between 1977 and 2009, civilian fire deaths declined from 7,395 to 3,010 respectively. Flame retardants have played a key role in reducing the incidence of fire. Unfortunately, despite the perceptions of some that fires are no longer a cause for concern, fire dangers continue to exist. The NFPA reported that in 2009: 1,348,500 fires were reported in the United States These fires caused 3,010 civilian deaths and 17,050 civilian injuries. All fires caused $12.5 billion in property damage. A fire department responded to a fire every 23 seconds. One civilian fire injury was reported every 31 minutes. One civilian fire death occurred every two hours and 55 minutes. Flame retardants have proven to work and continue to be an important component in the overall effort to address the dangerous consequences of fire, prevent fire-related injuries and protect lives. The use of flame retardants in
flame retardant necessity for Polyurethane (PU) Products
2023 / 02 / 25
1.What are polyurethane products? Polyurethanes refer to a wide range of products that include flexible foams used in furniture and automobiles, rigid foams used as building insulation, durable coatings, adhesives and sealants, and even certain items of apparel. 2.Can polyurethane products burn? As with other common organic materials, polyurethane foam products are combustible when exposed to a sufficient ignition source. For that reason, to maximize their safety many polyurethane products are flame retarded or protected by a barrier that can delay ignition, retard combustion, reduce surface burning, or otherwise protect the material from fires. 3.Do polyurethane products emit smoke when burning? Yes. Like any material in a fire, the amount of smoke generated is dependent on a number of factors, including the amount and type of burning material, the amount of oxygen available, and the temperature of the fire. 4.Do polyurethane products produce a unique toxicity risk in fires? No. While a range of airborne chemicals may be emitted during fire events involving polyurethane products, all combustible materials produce toxic smoke when burned, including wood. In terms of hazard, carbon monoxide (CO) is typically the most abundant toxicant in fires under
Three Surprising Benefits of Using Flame Retardant at your House
2023 / 02 / 25
Flame retardants are products in a home that contain chemicals to decrease or eliminate their flammability, and they work in three different ways to inhibit or minimize the severity of a fire. A flame retardant will decrease the presence of oxygen as well as gasses located close to items that are burning. It will inhibit a material`s ability to ignite. Flame retardants also provide a layer of fire resistant material on a product. 1. Fire Prevention Flame retardants are able to provide a number of consumers products with an essential layer of fire protection. According to FireTect, flame retardants are able to stop fires from starting as well as limit their spread and decrease the amount of damage resulting from a fire. Some are designed to work on their own and others act as a synergist. This means they can increase the fire protective abilities of other types of flame retardants. Product manufacturers use a variety of flame retardants. The materials are very different in their chemical composition and physical nature. Various flame retardants react in different ways with fire. This is why so much care is taken to carefully match a flame retardant to the correct material. They all interact at various stages of a fire`s cycle. A home today contains a number electronic devices such as computers, televisions, microwaves and more. This has resulted in high amounts of composite and plastic materials available in a home. It has significantly increased the fire hazard po
How Flame Retardants Are Used in Building and Construction
2023 / 02 / 18
Flame retardants are used in building materials and products to meet important fire safety standards and codes. Flame retardants stop or slow the spread of fire and provide critical escape time should a fire start, which is especially important for the most vulnerable populations. Learn more how flame retardants work. In research results released in May 2011, the National Fire Protection Association found the populations at highest risk for home fire-related deaths were children under the age of five and seniors over the age of 65. Specifically, flame retardants are used to raise the threshold temperature at which a material ignites, reduce the rate at which materials burn, and minimize the spread of flames. Three major categories of building materials that require the fire-protective benefits of flame retardants include cables and electrical wires, insulation and structural elements. Cables and Electrical Wiring Today`s modern structures contain a large volume of electrical wires and cables to power EEE from phones and computers to heating systems and elevators. Electrical and communications equipment that feeds into various rooms of a building is usually bundled together and can run vertically from floor to floor behind the walls of a structure, potentially increasing the fire risks from short circuits and other electrical malfunctions. If one wire is the cause of a fire, for example, it potentially affects all of those in proximity.
What are the protective benefits of flame retardants?
2023 / 02 / 18
Flame retardants play a unique role in fire prevention and fire safety. They not only prevent fires from starting, but if a fire does occur, they slow down the spread of the fire and improve the opportunity for safe escape. Their role in delaying flashover, for example, is especially critical to escaping the deadly consequences of fire. Flashover occurs when every flammable object in a room bursts into flames at the same time as a result of a combination of intense heat and the release of flammable gases. This can occur in just a few minutes, and flame retardants` function in slowing this process down can be the difference between life and death. The benefits of flame retardants are well documented in studies and in real life examples. The August 2005 fiery crash of a passenger jet in Toronto, Canada, in which all 309 people aboard survived, is one example. On August 5, 2005, the Washington Post reported, [The fire-retardant material now required in aircraft cabins may have helped slow the spread of flames and smoke, enabling all crew members and passengers to escape." The plane was subject to [new regulations requiring fire-retardant treatment of seat cushions, carpet and other materials-" In September 2009, at a conference on flame retardants and firefighter health, the Materials Flammability Group of

Electrical and Electronic Equipment: Types of Flame Retardants Used in EEE Applications
2023 / 02 / 11
Flame retardants are an important component in reducing the devastating impact of fires on people, property and the environment. Their areas of application in electrical and electronic equipment (EEE) vary depending on the materials being used, the function of the product, and the level of fire resistance that must be achieved based on fire safety standards. Flame retardants have unique characteristics, and, as a result, need to be matched appropriately to the materials used. In wires and cables, for example, the flame retardants used must meet fire safety requirements developed specifically for these products because they have the potential for spreading a fire to the electrical socket, and to walls and curtains. The level of flame retardancy required for printed wiring boards used in consumer mobile phones is different than that of wiring boards used in computer servers or in telecommunications or aerospace applications. Higher electrical and mechanical performance demands must be met with flame retardants that can achieve higher flammability and fire resistance standards, without affecting a product`s performance specifications. When it comes to fire safety, one size does not fit all. Specific flame retardants must be selected carefully to meet fire safety standards, electrical and mechanical requirements. The following classes of flame retardants used in EEE include: · Bromine-based

Fast Facts on Fire Safety and Flame Retardants
2023 / 02 / 04
Recent news reports about flame retardants have been one-sided, inaccurate and misleading. The following facts clear up some of the misconceptions about flame retardants and highlight the benefits of this important fire safety tool. FIVE FAST FACTS: The threat of fire is still a serious problem. Flame retardants have played a key role in reducing the incidence of fire. But unfortunately, despite the perceptions of some that fires are no longer a cause for concern, fire dangers continue to exist. The National Fire Protection Association (NFPA) reported that in 2011: 1,389,500 fires were reported in the United States These fires caused 3,005 civilian deaths and 17,500 civilian injuries All fires caused $11.7 billion in property damage A fire department responded to a fire every 23 seconds One civilian fire injury was reported every 30 minutes
2023 / 02 / 04
Flame retardants are generally classified according to their chemical makeup. The most common classes of flame retardants are: Brominated, Phosphorus, Nitrogen, Chlorinated and Inorganic. Brominated Brominated compounds are used for a number of purposes, but the major use is as flame retardants. Bromine interacts with the fire cycle in the gas phase to stop the chemical chain reaction that leads to flame formation and a self-sustaining fire. In essence, brominated flame retardants either prevent a fire from starting in the first place, or significantly slow a fire down. Brominated compounds also can be added to materials like plastic without altering their properties. As a result, they can be used in many applications. Highly effective, brominated flame retardants are used in a variety of materials, including textiles, electronics, building materials, plastics and foams. They are often used in combination with an antimony trioxide synergist. Phosphorus Flame retardants containing phosphorus interrupt the combustion process by promoting [charring." In the presence of a heat source, phosphorus flame retardants release phosphoric acid which causes the material to char and form a thick glassy layer of carbon. This carbonated char stops the decomposition process (pyrolysis) and prevents the release of flammable gases, essentially cutting off fuel to the flame. It also provides a barrier

PVC is popular because it is strong and moldable. Manufacturers can heat it up and turn it into all different kinds of products, such as piping, siding, cable insulation, signs and more. To build upon those advantages in CPVC, the PVC homopolymer is subjected to a chlorination reaction. The chlorine (C2) and PVC resin react through a basic free radical mechanism, typically initiated by thermal and/or UV energy. The chart below shows the molecular difference between CPVC (left) and PVC (right), where the large chlorine atoms (red) increase exhibit the increased protection of the carbon backbone. In PVC, chlorine atoms occupy 25% of the bonding sites, and the rest are filled by hydrogen. The CPVC carbon backbone, in contrast, has approximately 40% of bonding sites filled by chlorine. The increase in large chlorine molecules is the key to protecting the backbone from decomposition. The most noticeable change from PVC to CPVC is its heat distortion temperature and pressure rating at elevated temperatures. PVC is pressure rated for use up to 140°F (60°C), while CPVC is approved for use up to 200°F (93.3°C). When industrial processing applications involve higher temperature and/or higher pressures, CPVC may be used. After the CPVC resin is formed from the PVC, Corzan Industrial Systems infuses it with additives that enhance other inherent properties, such as UV weatherability. Finally, the CPVC compound is produced as pellets or powder. CPVC resin producers-such as Corzan Industrial Systems-create compounds for partner manufacturers who produce pipes, fittings, sheet and more. The resin producers must produce compounds that fit the partner manufacturers` applications and manufacturing requirements.
How Melt CPVC Resin into Finished Products
2023 / 02 / 01
There are two common processes for creating finished CPVC products: extrusion and injection molding. CPVC Extrusion To create long, continuous shapes-such as piping and sheet-extrusion is employed. In extrusion, manufacturers take CPVC powder and feed it into an extruder. The extruder melts it and pushes it through a die head, which spreads it out as evenly as possible and forms it into the final shape. Then, as the material moves through the processing equipment downstream of the extruder, it is corrected to fix any disproportions. The pipe or sheet is then cooled, hardened, cut and prepared for use-usually in 10 or 20-foot sections of pipe or 4 ft. by 8 ft. sheets (in North America). Extrusion is efficient for creating pipes and sheet because the machine can run continuously, as long as material continues to be fed into the system, until a new product size must be made. CPVC Injection Molding To create the rest of the CPVC products available to the market-such as fittings, valves, flange adapters-manufacturers use CPVC pellets for injection molding. They use machines (like those in the image below) with a hopper on the top that feeds a specified amount of CPVC into the system. The system uses a high-pressure screw to melt down the CPVC and push it into the desired mold. After a few seconds of cooling, the CPVC is dropped out of the mold in perfectly formed, ready-to-use pieces.
