Polycarbonate (PC) is a family of thermoplastic polymers. It can be widely used in molding and thermal modification. These types of plastics are widely used in modern chemical industries. It was first commercially introduced in 1956 by Bayer. Its raw material is bisphenol A (obtained from the combination of phenol and acetone) and fushene (obtained from the combination of chlorine gas and carbon monoxide) in a solution of bisphenol and the caustic soda with a temperature of 30 ف F inserted into the reactor, and in the vicinity of the catalyst and the temperature of 130 to 300. C, the polymer is obtained, which, after leaving the dry reactor, is extruded and converted into granules. This material can be formed by injection machines and extruders, and also hot rollers can be used to turn in to sheets if needed. These materials are relatively more expensive than PE, PP, PS, PET materials. Advantages 1- High impact resistance, 2- Excellent transparency, 3- Thermal stability from 110 to 130 degrees Celsius, 4- This polymer does not absorb water.
