Physical property

Polycarbonate is colorless and transparent, heat-resistant, impact resistant, flame retardant, and has good mechanical properties even at normal operating temperatures. 

Compared with methyl methacrylate with similar performance, polycarbonate has better impact resistance, higher refractive index, better processing performance, and UL94 V-2 flame retardant performance without the need for additives. However, the price of polymethyl methacrylate is relatively low and large-scale devices can be produced through bulk polymerization. 

Currently, with the increasing production scale of polycarbonate, the price difference between polycarbonate and polymethyl methacrylate is narrowing.When polycarbonate is burned, it emits pyrolysis gas, causing the plastic to burn and bubble, but it does not ignite. It extinguishes immediately from the ignition source and emits a thin phenol odor. The flame is yellow and emits light black light. It begins to soften at a temperature of 140 ℃ and melts at 220 ℃, and can absorb infrared spectroscopy.Polycarbonate has poor wear resistance. Some polycarbonate devices used for wear and tear purposes require special surface treatment.
