With the development of petrochemical industry, polyethylene production has developed rapidly and is widely used, such as in plastic prototypes.Polyethylene (PE) is a kind of odorless, non-toxic thermoplastic resin made by polymerization of ethylene. It has excellent low temperature resistance (the lowest use temperature can reach -100~-70°C), chemical stability, and can withstand the erosion of most acids and alkalis (not resistant to acids with oxidizing properties). It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation.

Properties of Polyethylene

Light weight
Good heat resistance and cold resistance
Excellent electrical insulation
Acid and alkali resistance
Organic solvent resistance
Good flexibility and extensibility ,easy processing


Polyethylene is one of the most commonly used plastics in daily life, and is widely used in the manufacture of plastic bags, films, barrels and other products.
•Packaging field
•Electrical machinery and
equipment manufacturing industry
Polyethylene plastic is widely used in rapid prototyping, through CNC machining and 3D printing technology to make prototype parts, polyethylene plastic prototypes are used in aviation, automotive, robotics, communications, toys, consumer electronics, sports equipment. Polyethylene plastic has good plasticity and is widely used in rapid prototyping.
