Read:
The difference between polyvinyl chloride and polyethylene is that polyvinyl chloride plastic produces a pungent odor and thick smoke during combustion, while polyethylene is the opposite.

Polyethylene is a thermoplastic resin made by polymerizing ethylene.

Polyvinyl chloride is an initiator of vinyl chloride monomer in peroxides, azo compounds, etc; Or polymers formed by free radical polymerization reaction mechanism under the action of light and heat.

Polyethylene (PE) is a thermoplastic resin made by polymerizing ethylene. In industry, it also includes copolymers of ethylene with small amounts of alpha olefins. Polyethylene is odorless, non-toxic, and feels like wax. It has excellent low-temperature resistance (with a minimum operating temperature of -100~-70 ° C), good chemical stability, and can withstand most acid and alkali corrosion (not resistant to acids with oxidative properties). Insoluble in general solvents at room temperature, with low water absorption and excellent electrical insulation.
