Product introduction
PBS-64HW is a homopolymer of Di brominated styrene, which is mainly used for the brominated styrene homopolymer flame retardant of polyamide resin and thermoplastic polyester resin (PBT and PET). The main features of PBS-64HW are:
Excellent thermal stability and color stability;
No migration, no frost.
Melting can be mixed and easy to process.
The products are flaky, easy to use, low dust.
