Polyethylene & polypropylene are members of the polyolefine family of thermoplastics. The various grades of these materials have similar properties. Compared to other types of thermoplastic they all have low densities and negligible water absorption. Polyolefines have very good resistance to chemicals, this means whilst ideal for manufacturing tanks, tubs and baths they are practically impossible to solvent bond or glue. Engineering & Design Plastics offer a fabrication service in polypropylene and HD-PE300 by hot air welding the parts together.

HMW-PE500 is generally supplied in sheet form already planed to close tolerances and can perform at temperatures as low as -50şC. It also boasts a higher wear resistance than PE 300 giving it a wider range of applications within all aspects of industry. PE 500 is widely used for its impact resistance in applications such as cutting boards, fenders, hand rails and protection strips where repeated impact is expected.



Main characteristics

  • Good wear resistance (UHMW-PE1000 is better)

  • Good Abrasion resistance (UHMW-PE1000 is better)

  • High impact strength, even at low temperatures (UHMW-PE1000 is better)

  • Excellent chemical resistance

  • Low density compared to other plastics

  • Low coefficient of friction

  • Excellent Release properties

  • Very low water absorption

  • Physiologically inert (suitable for food contact)

  • Moderate mechanical strength, stiffness & creep resistance

  • Very good electrical insulation and dielectric properties

  • Excellent machinability

  • Not self-extinguishing

  • Good resistance against high energy radiation
