Why do international companies abolish halogen flame retardant plastic products?

At present, many large international companies are actively promoting the complete abolition of halogen-containing materials, such as banning the use of halogen flame retardants in their products. These halogen-containing flame retardant materials produce dioxins when they are burned, and they can exist in the environment for many years, or even accumulate in the organism for life, and cannot be discharged.

Moreover, these plastic products containing halogen flame retardants generate a large amount of smoke and toxic and corrosive gases when they are burned, which is very harmful. Once a fire occurs, due to thermal decomposition and combustion, a large amount of smoke and toxic corrosive gases will be generated, which will hinder fire fighting and personnel evacuation, and corrode equipment and equipment. In particular, people have found that more than 80% of fatalities in fires are caused by dense smoke and toxic gases produced by materials.

Halogen compounds are often used as flame retardants: PBB, PBDE, TBBP-A, PCB, tribromophenol, short-chain chlorinated paraffin, etc., used in electronic components and materials, product shells, plastics, etc. . This kind of flame retardant cannot be recycled and used, and it will release harmful substances during the combustion and heating process, threatening human health, the environment and the next generation of children.

Halogen-free came into being

At present, different products have different limit standards for non-halogenation requirements:

For example, the halogen index of the halogen-free wire and cable is the value of all halogens ≦50PPM;

Halogen-free requirements: the content of bromine and chlorine is less than 900ppm, and (bromine + chlorine) is less than 1500ppm.

Halogen-free flame retardant is compared with halogen (such as chloroform bromide and other halogen elements) flame retardant materials. Halogen-free flame retardant materials have many advantages. First of all, low density. Common halogen 30 fiber PBT, PA is 1.6 However, the halogen-free PA is around 1.42, and the PBT is around 1.53; followed by the tracking index (CTI). The ordinary halogen-free flame-retardant materials generally do not exceed 250 volts, while the CTI of halogen-free flame-retardant materials can be as high as 550- 600 volts; the last is the low density of smoke when burning and less smoke.
