No. Nylon is hard and has high temperature resistance, and is suitable for making shells, tools, gears, etc. Polyethylene is soft and has low temperature resistance. It can be blown into films and made into bottles.
Polyethylene (PE) is a thermoplastic resin prepared by polymerization of ethylene. 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, good chemical stability and resistance to most acid and alkali corrosion. Insoluble in general solvents at room temperature, with low water absorption and excellent electrical insulation. Polyethylene has general mechanical properties, low tensile strength, poor creep resistance and good impact resistance. Polyethylene can be processed by blow molding, extrusion and injection molding, and is widely used in the manufacture of films, hollow products, fibers and daily necessities.
Polyamide is commonly known as Nylon, and its English name is Polyamide (PA for short), with a density of 1.15g/cm. It is a general term for thermoplastic resins with repeated amide groups -[NHCO]- in the molecular backbone, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its name depends on the specific number of carbon atoms in the synthetic monomer. It was invented by the famous American chemist carothers and his research team.
