Plastic
Plastics are macromolecules made from monomers through addition polymerization or condensation polymerization. Microplastics can harm human health.Its deformation resistance is medium, between fiber and rubber, and it is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastic is resin. Resin refers to a high molecular…

ABS Plastic
ABS plastic is a ternary copolymer of acrylonitrile (A), butadiene (B) and styrene (S). The relative contents of the three monomers can be changed arbitrarily to make various resins. ABS plastic has the common properties of three components. A makes it resistant to chemical corrosion and heat, and has a certain surface hardness. B makes…

Polypropylene (pp)
Polypropylene, abbreviated as PP, is a polymer formed by the addition polymerization of propylene. It is a white waxy material with a transparent and light appearance. The chemical formula is (C 3 H 6 ) n, and the density is 0.89 to 0.91 g/cm 3. Flammable, melting point 164~170℃, It softens at around 155°C and…

High Density Polyethylene (HDPE)
High-density polyethylene (HDPE) is a white powder or granular product. It is non-toxic, odorless, with a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and an operating temperature of up to 100°C; its hardness, tensile strength and creep are better than those of low-density polyethylene; it has good wear resistance, electrical…

Degradable Plastics
Degradable plastics refer to a type of plastic whose products have various properties that can meet the use requirements, and whose properties remain unchanged during the shelf life, and which can be degraded into environmentally friendly substances under natural environmental conditions after use. Therefore, they are also called environmentally degradable plastics. There are many new…

Polyethylene (PE)
Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene monomers. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, and has excellent low-temperature resistance (the lowest operating temperature can reach -100~-70°C). It has good chemical stability because the polymer molecules are…
