Plastic raw materials are mainly divided into thermoplastic and thermosetting plastics according to the molecular structure of synthetic resin: for thermoplastic plastics, plastics that are still plastic after repeated heating: mainly PE / PP / PVC / PS / ABS / PMMA / POM / PC / PA Commonly used raw materials. Thermosetting plastics mainly refer to plastics made by heat-hardening synthetic resins, like some phenolic plastics and amino plastics, which are not commonly used.
The main component of plastic toys is resin.
The raw material of plastic toys: it is made of polymer synthetic resin (polymer) as the main component and infiltrated into various auxiliary materials or additives.It has plasticity and fluidity at a specific temperature and pressure, and can be molded into a certain shape under certain conditions Under the shape of the material.
Polymer: Refers to the pure material or polymeric material produced by the polymerization process. Both natural resins and synthetic resins are high molecular polymers, referred to as high polymers.
Plastic has good insulation to electricity, heat, and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, and excellent sound absorption performance.
Most of the plastic toy raw materials are extracted from some oils. The most familiar part of the PC material is extracted from petroleum. The PC material has a gasoline smell when it is burned; ABS is extracted from coal, ABS It will be soot when it is burned out; POM is extracted from natural gas, and POM will have a very smelly gas smell when it is burned.
