High-Strength Flame Retardant Polybutylene Terephthalate

Product properties:

ACCOM’s high quality High-Strength Flame Retardant Polybutylene Terephthalate possesses excellent flame retardancy, complying with the UL94 V-0 rating (0.8mm/1.6mm), effectively inhibiting flame spread.

It passes the Glow-Wire Test (GWT) and High-Current Arc Ignition Test (HAI), making it suitable for high-safety scenarios.

Some halogen-free formulations also feature low smoke and low toxicity, reducing secondary hazards during fires.

Simultaneously, it offers high strength and rigidity; with the addition of 15%-30% glass fiber reinforcement, its tensile strength reaches 120-160 MPa and flexural modulus reaches 8,000-10,000 MPa.

It also exhibits excellent creep resistance and dimensional stability, making it suitable for precision structural components. In terms of electrical properties, it performs exceptionally well, featuring high volume resistivity (>10¹⁵ Ω·cm) and dielectric strength, along with a high Comparative Tracking Index (CTI > 600V), ensuring resistance to high-voltage arcing.

High-Strength Flame Retardant Polybutylene Terephthalate further demonstrates good heat resistance and chemical resistance, with a Heat Deflection Temperature (HDT) reaching over 200°C (under 1.8 MPa load), and resistance to weak acids, weak alkalis, oils, greases, and various organic solvents.

Additionally, the material offers processing convenience:good flow properties facilitate easy injection molding of complex, precision parts, and low moisture absorption eliminates the need for prolonged drying before molding.
