Plastic is a material that uses natural or synthetic resin as the main component and adds various additives. It is molded into a certain shape under specific conditions of temperature and pressure, and can maintain the shape unchanged at room temperature. The gases produced during the compression molding of plastic products are usually produced by the volatilization or decomposition of additives, resin decomposition products and other organic compounds in the plastic under high temperature and pressure conditions.
