PC-GF20
Polycarbonate
Product Description：
Black
PC+20%GF, Glass fibers may be added in various amounts (20% and 30%) to increase tensile strength, stiffness, compressive strength, and lower the thermal expansion coefficient. Unfilled Polycarbonate is a tough, transparent engineering thermoplastic which offers very high impact strength and high modulus of elasticity. It also has a high heat deflection temperature and absorbs very little moisture. These properties, plus good low frequency and high voltage insulating characteristics, make polycarbonate a prime material for electrical and electronic components. Its strength, impact resistance and transparency (unfilled grades only) also make it an ideal material for certain transparent structural applications.
