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.
JUTAIPSU?NA type pure PSU profiles:
●High tensile strength, the strength is above 85MPa;
●High bending strength, the strength is above 120MPa;
●Excellent thermomechanical load-carrying capacity, thermal deformation temperature is greater than 170℃;
●Good creep resistance and fatigue resistance;
●Excellent flame-retardant performance, low-smoke combustion;
●Excellent dielectric and insulation;
●Excellent dimensional stability, low thermal expansion coefficient;
JUTAIPSU?NA type pure PSU profiles can be applied:
——Electronics industry: connectors, coil bodies, high-frequency insulators, lamp sockets, parking covers and antenna sockets;
——Mechanical engineering: oil level indicator;
——Food industry: microwave tableware;
——Chemical industry: valve cores, flanges, pipes, pump casings and inspection windows.
Machined by Lathes or Milling Machine. Remove surface heat-treatment aged layers and the thickness of removal layer is 0.5-1mm.
Placed away from light, avoiding humid, and away from oily substance.
Packed with polymeric film when not use.
