Synthetic resin type

A wide variety of synthetic resins. According to the main chain structure, there are carbon chain, hetero chain and non-carbon chain synthetic resins; according to the synthetic reaction characteristics, there are polyaddition type and polycondensation type synthetic resin. In practical applications, thermoplastic resins and thermosetting resins are often classified according to their thermal behavior. Among them, the thermoplastic resin is polyethylene, polypropylene, polystyrene, polyvinyl chloride or the like. Thermosetting resins are phenolic resins and urea-formaldehyde resins, epoxy resins, fluororesins, unsaturated polyesters and polyurethanes.
