Polycarbonate PC films, rolls, and sheets have excellent impact resistance, high tensile strength, bending strength, and compressive strength; Low creep resistance and stable size; Good heat and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties, and flame retardancy over a wide temperature range, suitable for long-term use at **0~**0 ℃; No obvious melting point, in a molten state at ******0 ℃; Due to the high rigidity of the molecular chain, the viscosity of the resin melt is high; Low water absorption, low shrinkage, high dimensional accuracy, good dimensional stability, and low permeability of the film; It belongs to self-extinguishing materials; Stable to light, but not resistant to ultraviolet light, with good weather resistance; Oil resistant, acid resistant, not resistant to strong alkalis, oxidizing acids, amines, ketones, and soluble in chlorinated hydrocarbons and aromatic solvents. Long term exposure to water can easily cause hydrolysis and cracking. The disadvantage is that due to poor fatigue strength, stress cracking is prone to occur, solvent resistance is poor, and wear resistance is poor.
