PC is a mixture of polycarbonate and acrylonitrile butadiene styrene, and a combination of polycarbonate and acrylonitrile butadiene styrene copolymer. Functional features: 1. Good comprehensive performance, high impact strength, good chemical stability and good electrical properties. 2, good weldability, made of two-color plastic parts, chrome plated and painted. 3. It has high impact resistance, high heat resistance, flame retardancy, reinforcement and transparency. 4. The fluidity is slightly worse than HIPS, but better than PMMA and PC, and it has good flexibility. 5. Excellent balance of mechanical properties.
