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.

Having the highest molecular weight of all Polyethylene, Ultra High Molecular Weight [UHMW-PE1000], (HD1000) is the most wear resistant. Particularly suited to applications such as chain guides, star wheels, wear strips etc. and can operate as low as -270şC.

By the addition of a proportion of regenrated PE 1000 we can offer a more cost effective sheet whilst still retaining much of its excellent wear and impact resistance. Particularly suited to linings and wear applications where a lower cost alternative is required.

Ultra High Molecular Weight Polyethylene blocks machined to our customer's specification to be used as part of a piece of outdoor children's play equipment to create a "noughts and crosses" game.
