PS material main performance
General purpose polystyrene liquidity, processing performance, easy to color, good dimensional stability. Available injection molding, extrusion, blow molding, foam, thermoforming, bonding, coating, welding, machining, printing and other methods into a variety of parts, especially for injection molding.
The main performance
a, mechanical properties: high strength, fatigue resistance, dimensional stability, creep is also small (high temperature conditions rarely change);
PS plastic sheet
PS plastic sheet
b, heat aging: enhanced UL temperature index of 120 ~ 140 ℃ (outdoor long-term aging is also very good);
c, solvent resistance: no stress cracking;
d, water stability: easy to break down in water (high temperature, high humidity environment need to be cautious);
e, electrical performance:
1, Insulation: Excellent (humid, high temperature can also maintain electrical stability, is the ideal material for the manufacture of electronic and electrical parts);
2, dielectric coefficient: 3.0-3.2;
3, arc resistance: 120s
f, molding processability: ordinary equipment injection molding or extrusion. As the crystallization speed, good fluidity, mold temperature is also lower than other engineering plastics requirements. In the processing of thin-walled parts, only a few seconds, only 40-60s for large parts can be.
a, electronic appliances: connectors, switch parts, household appliances, parts accessories, small electric cover or (heat resistance, flame retardancy, electrical insulation, forming processability)
Material performance editing
Excellent electrical insulation (especially high frequency insulation), colorless and transparent, light transmittance second only to plexiglass, tinting water resistance, good chemical stability, strength, but brittle, easy to produce stress brittle crack, impatience Benzene, gasoline and other organic solvents. Suitable for the production of transparent insulation pieces. Decorative parts and chemical equipment. Optical instruments and other parts.
⒈ amorphous material, hygroscopic small, do not have to fully dry, not easy to decompose, but the thermal expansion coefficient, easy to produce internal stress. Good mobility, available screw or plunger injection molding machine.
⒉ appropriate to high feed temperature, high mold temperature, low injection pressure, prolonged injection time is conducive to reducing the internal stress, to prevent shrinkage. Deformation.
⒊ Various forms of gate can be used, the gate and the plastic arc connection, so as not to damage the gate when the gate parts. Stripping large, uniform top. Plastic wall thickness, preferably without inserts, such as There are inserts should be preheated.
