Varieties of polyethylene | MULAN

The following are some commonly used polyethylene varieties:

Medium Density Polyethylene (MDPE)

MDPE is a kind of plastic that can maintain its strength for a long time and resist environmental stress cracking. MDPE density 0.926~0.953g/cm3, crystallinity 70~80%, tensile strength 8~24 MPa, elongation at break 50~60%, melting temperature 126~135℃.

MDPE is mainly used in pipes, films, hollow containers, etc. Including all kinds of bottles, packaging films, injection products, rotary molding products, water pipes, waterproof materials, wire and cable cladding.

Ultra-High Molecular Weight Polyethylene (UHMWPE)

UHMWPE is a kind of thermoplastic engineering plastic with linear structure and excellent comprehensive properties.

UHMWPE density 0.920 ~ 0.964g/cm3, thermal deformation temperature 85℃(at 0.46MPa), melting point 130 ~ 136℃. UHMWPE has the highest specific strength among chemical fibers, with good wear resistance, impact resistance, corrosion resistance, light resistance and other excellent properties.

UHMWPE is widely used in various fields. It is often used in cables, sails, fishing rods, skis, gliders, parachutes, hard hats, etc.UHMWPE can be used for gears, pulleys, bearings, gaskets and other components in industry, body armor, armor plates, protective covers in military, and graft materials in medicine.

Chlorinated Polyethylene (CPE)

CPE is a kind of polymer material prepared by the chlorination substitution reaction of HDPE. The appearance is white powder, non-toxic and tasteless, with excellent weather resistance, ozone resistance, chemical resistance and aging resistance, with good oil resistance, flame retardant and coloring properties.

CPE is a new type of synthetic material with a series of excellent properties. It is an excellent impact modifier of PVC plastic, and also a synthetic rubber with good comprehensive performance. CPE is widely used in many fields, including cable, wire, hose, rubber cloth, rubber and plastic products, sealing materials, flame-retardant transport belts, waterproof coils, films and various profiled products.
