PSU

JUTAIPSU®NA is a polysulfone plastic (PSU) profile. PSU is an amorphous polymer with a glass transition temperature of 188°C. PSU is a transparent engineering plastic with good chemical resistance, rigidity and temperature resistance. PSU has mechanical and electrical properties similar to PEI. Due to the conjugated benzene rings and sulfone groups in the polymer, the PSU profiles exhibit high resistance to acid and salt solution corrosion, as well as good resistance to detergents, hot water, and steam. In addition, PSU has excellent radiation resistance and low levels of ionic impurities. Special attention is that the PSU will greatly reduce the insulation, strength and other indicators under ultraviolet radiation.
