Polycarbonate is colorless and transparent, heat resistant, impact resistant, flame retardant BI class, and has good mechanical properties in ordinary use temperatures. Compared with similar properties of polymethyl methacrylate, polycarbonate has good impact resistance, high refractive index, good processing performance, and has UL94 V-2 flame retardant performance without additives. However, the price of polymethyl methacrylate is lower than that of polycarbonate, and large-scale devices can be produced by bulk polymerization.
The wear resistance of the material is relative, and the
Abs Material is compared with the PC material, that is, the wear resistance of the PC material is better. However, compared with most plastic materials, the wear resistance of polycarbonate is relatively poor and is in the middle and lower level, so some polycarbonate devices for easy wear purposes require special treatment of the surface mechanical properties
PC Or ABS Component property
Major advantage
Apply
With high strength and elastic coefficient, high impact strength,
Polypropylene good fatigue resistance, good dimensional stability, low creep (there is little change under high temperature conditions), high transparency and free dyeing;
The use temperature range of heat aging is wide, and the UL temperature index after enhancement reaches 120~140℃(outdoor long-term aging is also very good):
No stress cracking
Water stability Easy to decompose in high temperature water (use caution in high temperature and high humidity environment)
Insulation property
Excellent (wet, high temperature can also maintain electrical stability,Polyformaldehyde is the ideal material for manufacturing electronic and electrical parts)
Dielectric coefficient 3.0-3.2
Arc resistance 120s
General equipment for molding processing injection molding or extrusion.
