1、 The main ingredient of plastic raw materials is resin.
2. Plastic raw materials: It is made of polymer synthetic resin (polymer) as the main ingredient and penetrates into various auxiliary materials or additives. It has plasticity and fluidity under specific temperature and pressure, and can be molded into a certain shape and under certain conditions. Material that remains unchanged.
3. Polymer: Refers to the pure material or polymer material produced during the polymerization process. Both natural and synthetic resins are polymer aggregates, referred to as high polymers.
4. Plastic has good insulation properties against electricity, heat and sound: electrical insulation, arc resistance, heat insulation, sound insulation, sound absorption, vibration absorption, and excellent sound insulation performance.
