Polyethylene  is a thermoplastic resin obtained by polymerizing ethylene. Industrially, copolymers of ethylene and a small amount of an α-olefin are also included. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance minimum use temperature can reach , good chemical stability, and can resist most acid and alkali corrosion not resistant to oxidation Nature of acid.

It is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation. Polystyrene  refers to a polymer synthesized by free radical addition polymerization of styrene monomer, and the Japanese name is hydrazine. It is a colorless, transparent thermoplastic with a glass transition temperature above Polypropylene is a non-toxic, odorless, tasteless, milky white high crystalline polymer with a density of only , which is one of the lightest varieties of all plastics.

It is particularly stable to water. The water absorption in water is only 0.01%, the molecular weight is about  The moldability is good, but the shrinkage rate is large. The thick-walled products are easy to be sunken, and some dimensional precision is high. Parts, it is difficult to meet the requirements, the surface gloss of the product is good. ABS plastic is a ternary copolymer of acrylonitrile, butadiene , styrene  three monomers, the relative content of the three monomers can be Arbitrarily changed to make various resins.

ABS has the common properties of three components, A makes it resistant to chemical corrosion, heat, and has a certain surface hardness, B makes it highly elastic and tough, and makes it thermoplastic. Plastics are processed and molded to improve electrical properties. Therefore, ABS plastic is a raw material that is easy to obtain, has good comprehensive performance and is inexpensive.
