Halogen-free flame retardant is the future direction of flame retardant development

  HC Plastics Network News: Halogen-based flame retardant is the world's largest production of flame retardants, including brominated flame retardants. There are few types of chlorine-based flame retardants produced in industry, mainly chlorinated paraffins, clones, and special acid anhydrides. The commonly used chlorine-containing flame retardants in rigid polyurethane foams are tris (2-chloroisopropyl). Phosphate (TCPP), trichloroethyl phosphate (TCEP).

       Halogen-based flame retardants have a good flame retardant effect and a large market demand, but halogen-based flame retardants generate large amounts of smoke, corrosive gases, and toxic gases that are harmful to the human body and the environment during combustion. With the increasing awareness of environmental protection worldwide, this article comes from the global plastics network pvc123.com. Countries have gradually introduced various laws and regulations to gradually limit and prohibit the use of halogen-containing flame retardants. Therefore, from the perspective of long-term development, there is no halogen resistance. Burning is the direction of future flame retardant development.
