Superior Flame Retardancy

POLYLAC PA-764B meets stringent UL 94 V-0, 5VB, and 5VA standards, ensuring fire safety in thin-walled applications like power panels or electronics housings. Reduces fire risks without compromising structural integrity.

Robust Mechanical Durability

With tensile strength up to 37 MPa and impact resistance (14 KJ/m² at 23°C), it withstands drops, vibrations, and daily wear. Perfect for printer casings, car audio consoles, or industrial equipment.

Reliable Heat Resistance

Vicat softening temperature of 102°C and HDT up to 93°C ensure stability in high-heat environments, such as coffee machines or automotive battery housings. Minimizes warping and deformation.

Applications

Electronics: Modems, power outlets, remote controls, DVD players.
Industrial Equipment: Machine boxes, cash register shells, projectors.
Automotive: Car battery housings, audio consoles.
Appliances: Coffee machines, front/rear TV frames, light boxes.
Office Tech: Printer casings, fax machines, multifunctional peripherals.
