Name: PSU, also known as: polysulfone Manufacturer: Gaelic German company board: thickness (6 to 50 mm) * Width 1000 mm * 2000 mm long bar: ￠ 6 ~ ￠ 200 mm * 1000 mm Application: microwave components, power hair parts, gas warming device components, food and industrial components, pumps, wheels, parts of electrical insulation components the pharmaceutical industry. Features: Good heat without deformation and heat aging properties are not (PSU at -100 ℃ to +160 ℃ to maintain stability). It has high hardness and stiffness, excellent dielectric insulation, is extremely difficult to hydrolysis, resistant to high-energy rays (which can pass through the microwave) but it has bad effects engraved sensitive, susceptible to polar solvents (ketones, aromatic hydrocarbons and chlorine carbonate 95 water) erosion. In accordance with UL94 standard, PSU can be self-extinguishing. Disadvantages: tensile crack performance in general, vulnerable to weather conditions affect.
