The purpose of using flame retardant to prevent plastics from touching flame is to ensure that plastics can have longer service life and increase the safety of using plastics appropriately. Generally speaking, polymer flame retardant technology is mainly divided into two types: additive and reactive, and in the so-called "plastics" concept, mainly additive-based. The flame retardant plastics were prepared by adding a matching flame retardant into the common granule, mixing it fully in the mixer, and then re-granulating in the mixing device with twin-screw extruder as the main part.
Why should plastics be added with halogen-free environmentally friendly flame retardants?
In most cases, plastic polymers cause or spread flames because they are organic compound plastics that break down into unstable, flammable products when heated. However, in many areas, such as electricity, electronics, transportation, construction, etc., regardless of the advantages of using plastic polymers How important is it that its use is limited by its own flammability, and the current use of synthetic polymers has greatly increased the likelihood of "fire" and "fire" occurring, which is closely related to everyone in the building.
If you want to meet the statutory fire protection requirements, you must add flame retardants to the plastic polymer, these additives have the following main role: slow down the burning or decomposition of the polymer time; reduce the emission of smoke; avoid the generation of droplets. In order to increase people's escape time, strict standards will be established to provide enough time to escape an environment.
