BX FR OP1020
Description
BX FR OP1020 is a halogen-free flame retardant based on organic phosphinates. The polymer with BX FR OP1020 will expand and crosslink when burning and form a stable carbon layer at the surface. The protective layer provides a heat insulation effect, reduces oxygen access and prevents the further spread of flame, playing a role in a fire retardant. The flame retardant is not hydrolyzed, not precipitated, has good self-extinguishing properties into carbon.
Application
BX FR OP1020 is white particle, developed especially for PBT. It is suitable for both glass fiber-reinforced PBT and non-reinforced PBT. The flame retardant PBT exhibits excellent physical and electrical properties. In glass fiber-reinforced PBT, NP1020 is usually sufficient to achieve the UL94 V-0 flame retardant requirements (at 1.6 mm thickness).Due to different formulations and processing conditions, the dosage of flame retardant may be different.
