What is POLTEC UHMW-PE(ULTROL)?

UHMW-PE (Ultra High Molecular Weigh Polyethylene) is a linear thermoplastic with a molecular weight in the range of average 3,000,000 to 10,000,000. It has 10 times molecular weight of high density polyethylene (HDPE). Even UHMW-PE is linear polymer, its density is low (about 0.935 g/cm3 determined on press molded sheet). The most important value characterizing the properties of polymers are density and molecular weight. Many of the mechanical properties of the product including yield stress and flexural and torsional rigidity depend particularly on density. While toughness (notched impact strength), especially at low temperatures, wear resistance, dimensional stability under heat and resistance to stress cracking all depend on molecular weight.

UHMW-PE is toughest engineering material to date. It has 10 times impact strength of common carbon steel. UHMW-PE fights abrasion and corrosion while contributing a low coefficient of friction. It weighs 1/7 the weight of steel, 1/3 the weight of aluminum, and outwears abrasion-resistant steel 3 to 1. The coefficient of friction is 0.14 or lower and the material does not require lubrication.

UHMW-PE has an exceptionally high resistance to chemicals and other media because of its non-polar structure as a high-molecular weight paraffin hydrocarbon. UHMW-PE is not a nutrient medium for microorganisms, and is therefore not attacked by them. This material can be used for marine fender and wastewater treatment application.

Raw material resin of UHMW-PE is not expensive, it can be made into sheets, bars, rods and angles. The application of UHMW-PE is broadly extended into various industries, not limited in engineering field.
