PPS Plastic In CNC Machining

PPS PPS CNC Machining

PPS plastic (polyphenylene sulfide) is a comprehensive performance of the thermoplastic special engineering plastics, its outstanding features are high temperature resistance, corrosion resistance and superior mechanical properties. Electrical insulation (especially high-frequency insulation) excellent, white hard and brittle, falling on the ground with a metallic sound, light transmission is second only to organic glass, coloring water resistance, chemical stability is good. There is excellent flame retardant, non-combustible plastic. General strength, good rigidity, but brittle, easy to produce stress brittle cracking; not resistant to benzene, gasoline and other organic solvents; long-term use temperature up to 260 degrees, in 400 degrees in the air or nitrogen to maintain stability. By adding glass fiber or other reinforcing materials modified, can make the impact strength greatly improved, heat resistance and other mechanical properties have also improved, the density increased to 1.6-1.9, molding shrinkage is smaller to 0.15-0.25%, suitable for making heat-resistant parts, insulation parts and chemical instruments, optical instruments and other parts.
