Plastic can be divided into single component and multi-component types. Single component plastics only contain synthetic resins that are essential in plastics. Organic glass is a type of plastic made from single component polymethyl methacrylate, while most plastics have fillers, hardeners, colorants, and other additives in addition to synthetic resins, making them multi-component plastics.

1. Synthetic resin

Synthetic resins are almost exclusively used in plastics. Resin is the most important component in plastics, serving as an adhesive that can bond other components of the plastic into a cohesive whole. Although adding various additives can change the properties of plastics, resin is the fundamental factor determining the type, performance, and use of plastics.

The commonly used types of resins in plastic decorative materials are:

Polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), phenol formaldehyde (PF), urea formaldehyde (UF), epoxy (EP), polyester (PR), polyurethane (PU), polymethyl methacrylate (PUMA), organosilicon (SI), etc.
