Polybutylene terephthalate

non-flame retardant:

auto-lighting:Mobility,and easy release and easy processing of shape, can be made from thin-walled and complex shaped products; High-gloss, and Al-effective; Good heat Resistance, good mechanical properties.

Reinforced grade:High mechanical strength, wear-resistant rub; Low moisture absorption, good dimensional stability; Mobility, and ease of processing molding; Good high and low temperature resistance.

Normal flame retardant:

Excellent mechanical properties, electrical properties and heat resistance; High flame retardancy; Mobility, and shortr molding cycles, better dimensional stability; Low Warpage, UV, high-impact, high-flame-retardant grade.

Environmental protection flame retardant:

Excellent mechanical properties, electrical properties and heat resistance; High flame retardancy; Mobility, and shorter molding cycles, better dimensional stability; Low warpage, UV, high-impact, high-flame-retardant, high CTI, RTI GWIT/GWFI, Meet the ROHS requiremets.

Non-halogen flame retardant:

Any color Halogen-free flame retardant material Excellent mechanical properties, electrical properties and heat resistance High CTI, GWIT/GWFI, meet ROHS requirments.
