GE Plastics said its new flame-retardant Valox polybutylene terephthalate resins are designed to meet current and future environmental regulations.
Valox ENH resins are non-brominated and nonchlorinated, making it easier for electrical and electronic products to comply with restrictions on disposal of hazardous substances, according to the Pittsfield, Mass., company. For example, the European Union enacted a directive restricting the use of polybrominated diphenyl ether and other hazardous substances.
Another directive requires plastics containing brominated flame retardants to be removed from products and treated separately at the end of the product's life. GE Plastics' removal of chlorinated flame retardants is aimed at heading off potential future restrictions related to that halogen as well.
Valox ENH4550, the inaugural grade with 25 percent glass fiber, has high ductility and strength, and beats standard PBT in high-heat properties, GE said.
