Name: PSU, also known as: PSF producers: Gail German company sheet: thickness (6 to 50 mm) * Width 1000 mm Length 2000 mm * Bar: ￠ 6 ~ ￠ 200 mm * 1000 mm Application: microwave components, power hair parts, gas warming device components, food industry parts, pump wheel, the pharmaceutical industry component parts of electrical insulation. Features: Excellent resistance to heat deformation and heat is not the performance of non-aging (PSU at -100 ℃ to +160 ℃ to be stable.) It has high hardness and stiffness, excellent dielectric insulation, is extremely difficult to hydrolysis, resistant to high-energy rays (available through the microwave) but it has bad effects carved sensitive, vulnerable to polar solvents (ketones, aromatic hydrocarbons and chlorine carbonate 95 water) erosion. In accordance with UL94 standard, PSU can be self-extinguished. Disadvantages: tensile cracking performance in general, vulnerable to weather conditions affecting.
