Pi-200 series is thermoplastic polyimide injection grade material, suitable for injection molding products. PI2001 and PI2002 for pure resin, the product has outstanding electrical insulation performance, can be widely used in high temperature insulation components, such as electronics, electrical connectors, insulation base, coil skeleton, also can be used as a temperature bracket. PI230CF and PI230GF are respectively carbon fiber and glass fiber reinforced thermoplastic polyimide composites. The mechanical properties of the molded products are more prominent, and the high-temperature resistance is also improved to a certain extent, and they have excellent corrosion resistance and wear resistance. With its excellent comprehensive performance, it can be widely used in aerospace, automobile, electronic appliances, precision machinery and other fields, such as gears, bearings, connectors, etc. It is an ideal material that can withstand high and low temperature, wear resistance and self-lubrication.
Special product requirements can be customized.
