Features & Benefits
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.
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.
