It is an integrated high performance thermoplastic special engineering plastics, its prominent feature is the high temperature, corrosion resistance and excellent mechanical properties. PPS is a sulfur-containing aromatic polymers, linear PPS after more than 350 ℃ crosslinked into a thermosetting plastic, branched-chain structure of PPS thermoplastics. PPS is the US company Phillips in 1971 industrial production in the first, after the patent expires, Japanese companies have begun to development and production. Japanese companies have a typical Japanese Toray, Japan's output stage is greater than US production. Some other manufacturers are mainly concentrated in the United States, Japan and Europe. PPS world's top five producers of Phillips, Toray, Ticona, Polyplastics, Dainippon Ink and physical properties 1, electrical insulation (especially high-frequency insulation) fine, white hard and brittle, falling on the ground with metal sound, transmittance after the plexiglass, colored water resistance, good chemical stability. It has excellent flame retardancy, non-combustible plastic. 2, the general strength, good rigidity, but crisp, easy to produce brittle fracture stress, impatience benzene gasoline and other organic solvents. Long-term use temperature up to 260 degrees, remained stable at 400 degrees in the air or nitrogen. Through the glass fiber or other reinforcing material modification can be greatly improved impact strength, heat resistance and other mechanical properties also increased, the density increased to 1.6-1.9, smaller mold shrinkage rate to 0.15-0.25% suitable Country resistant parts. insulation and chemical instruments optical instruments and other components.
