According to the molecular structure of synthetic resin, plastic raw materials mainly include thermoplastic and thermosetting plastics. For thermoplastic plastics, plastics that are plastically heated repeatedly: mainly PE/PP/PVC/PS/ABS/PMMA/POM/PC/PA And other common raw materials. Thermosetting plastics mainly refer to plastics made from heat-hardened synthetic resin, like some phenolic plastics and amino plastics, not commonly used.
The main component of plastic toys is resin.
Raw materials for plastic toys: Infiltrated into various auxiliary materials or additives by polymer synthetic resin (polymer) as the main component, which has plasticity and fluidity under specific temperature and pressure, can be molded into a certain shape, and under certain conditions. Keep the material in shape unchanged.
Polymer: refers to the pure material or polymer material produced by the polymerization process. Both natural resin and synthetic resin belong to polymer synthesizer, abbreviated as high polymer.
Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, excellent sound elimination performance.
Most of the raw materials for plastic toys are extracted from some oils. The most familiar PC materials are extracted from petroleum. PC materials have a gasoline smell when burned; ABS is extracted from coal, ABS It will be soot when burned out; POM is extracted from natural gas, and POM will have a very smelly gas smell when it is burned.
