Polybutylene Terephthalate, PBT for short, is a thermoplastic polyester resin derived from copolymerization of 1,4-butanediol and terepthalic acid (PTA). Fiber glass can be added in the later stage of production to ......More→
Semiconductor mold cleaners MC-261 and MC-701 are thermosetting resins formed by mixing melamine resin with organic and inorganic fillers. Our mold cleaners yield good results in removing residuals left on the mold after molding with epoxy resin materials. Due to the ......More→
Chang Chun phenolic molding compounds (under trade name of LONGLITE) are heat-hardening resins. Formulated based on the needs and usages of our customers, our phenolic molding compounds are produced by mixing different materials and pigments to the base phenolic resin which we ......More→
Polysulfone (PSU) is synthesized from Bisphenol A and 4,4'-Dichlorodiphenyl Sulfone. PSU offers excellent performance in chemical resistance, heat stability (heat deflection temperature of 170℃), and impact strength. With the above characteristics, PSU is a kind of high performance engineering thermoplastic resin.
TPEE is produced by 1,4-butanediol, polytetra-methylene glycol, and DMT or PTA going through copolymerization condensation. It also can be made into thermoplastic polyester elastomer composites through kneading procedure. TPEE possesses a ......More→
Used together with engineering plastics, nylon, phenolic molding compound, or polypropylene, glass fiber can strengthen the plastics materials.
We also offer phenolic resins as a hardening agent for the electronic industry. They offer good mechanical strength, dimensional/thermal stability, and resistance to electricity, solvent, and acid. They are widely used in molding materials (including ......More→
