Pps Material Performance

Product Details

pps material performance

1. Excellent electrical insulation (especially high-frequency insulation), white hard and brittle, metal noise when dropped on the ground, light transmittance second only to plexiglass, excellent water resistance, good chemical stability. It has excellent flame retardancy and is a non-combustible plastic. 2. The strength is general, the rigidity is good, but the quality is brittle, easy to produce stress brittleness, and is not resistant to gasoline, etc.. The long-term use temperature can reach 260 degrees, and it is stable in 400 degrees air or nitrogen. After modification by adding glass fiber or other reinforcing materials, the impact strength can be greatly improved, heat resistance and other mechanical properties are also improved, the density is increased to 1.6-1.9, and the molding shrinkage rate is as small as 0.15-0.25%. Production of heat-resistant parts, insulating parts, chemical instruments, optical instruments and other parts.
