Ultra high molecular weight Polyethylene (UHMWPE)is Polyethylene with a molecular weight numbering in the millions, usually between 3.1 and 5.67 million. The high molecular weight results in less efficient packing of the chains into the crystal structure as evidenced by densities of less than high density Polyethylene (for example, 0.930–0.935 g/cm3). The high molecular weight results in a very tough material. UHMWPE can be made through any catalyst technology, although Ziegler catalysts are most common. Because of its outstanding toughness and its cut, wear and excellent chemical resistance, UHMWPE is used in a wide diversity of applications. These include can and bottle handling machine parts, moving parts on weaving machines, bearings, gears, artificial joints, edge protection on ice rinks and butchers' chopping boards. It competes with Aramid in bulletproof vests, under the tradenames Spectra and Dyneema, and is commonly used for the construction of articular portions of implants used for hip and knee replacements.

Altec have over 30 years experience in manufacturing Plastic & Rubber Extrusions, Extruded Profiles and Tubing. We're quite rightfully proud of our reputation for consistently meeting the needs of customers over that time. Because we've remained small and focussed we've also remained more attentitive, more cost effective and more responsive than larger manufacturers.
