Material ScienceperformanceABS(acrylonitrile, butadiene, styrene)High impact strength, chemical stability, good electrical performance, good dimensional stability, small shrinkage, moderate price. But the temperature of heat deformation is low (high temperature resistance 70 ℃, low temperature resistance - 40 ℃), which is easy to aging, discoloration and even cracking, and easy to melt in aldehyde, ketone and vinegar.PC(polycarbonate)Impact resistance, good toughness, high transparency, creep resistance, good dimensional stability (temperature, depth, environment will not change with it), internal temperature up to 110 ℃ self extinguishing, small water absorption, good flame retardant and electrical insulation. However, when the internal force is large, it will crack; the injection molding rate is lower than ABS (ABS can be added)PA(polyamide, nylon)Wear resistance, toughness, non-toxic, cold resistance, corrosion resistance, small friction coefficient, easy to form, good electrical i...
