HIGH DENSITY POLYETHYLENE HD-PE300

 

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.

High Density Polyethylene (HD-PE300) has excellent impact strength, even at temperatures as low as -30şC. Coupled with low coefficient of friction and ease of fabrication, HD-PE300 is widely used in automotive, leisure and industrial applications and is particularly suitable for the fabrication of tanks, silos, hoppers etc. HD-PE300 can also be supplied to colour matched, talc-filed and conductive forms.
