It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants and colorants. The main component of plastic is resin. The basic properties of plastic are mainly determined by the nature of the resin, but additives also play an important role.

[0003] A plastic melting device for processing plastic products disclosed in the Chinese patent application disclosure CN217169277U relates to the field of plastic production technology and includes a melting box, which improves the stirring capacity of the equipment.
