UHMW-PE is defined as polyethylene whose molecular weight is 3.1 million or higher. When making this determination, it was found that physical properties increased rapidly as lower MW values increased, and then leveled off at the 3,100,000 value. As with most high-performance polymers, the processing of UHMW-PE is not easy. Because of its high melt viscosity, conventional molding and extrusion processes would break the long molecular chains that give the material its excellent properties. Current manufacturing methods include compression molding, ram extrusion and the warm forging of extruded slugs. UHMW-PE has the outstanding abrasion resistance and an extremely low coefficient of friction. Impact strength is high and chemical resistance is excellent.
The material does not break in impact strength tests using standard notched specimens; double-notched specimens break at 20 ft-lb/in (42.1 kJ/m2). UHMW-PE has a crystalline melting point of 267°F (131°C). The recommended maximum service is about 200°F (93°C).
Care should be taken when fastening UHMW-PE, as its large thermal expansion can cause the material to buckle between fasteners if they are too far apart.
UHMW (ultra-high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance.
The versatility of polyethylene has made it a popular plastic for countless industrial applications that require durability, low friction, and chemical resistance.
These wear strips are mounted on the tracks over which the chain travels. Special Antistatic grade of Ultra High Molecular Weight Polyethylene (UHMWPE having antistatic property ensures its suitability for LPG installations, reducing chances of sparks / static current developed because of friction. Various Rectangular, Square, Trapezoidal cross sections, "C" Profile , Special shapes, Curves etc. are available suitable for all installations. Installation of these liners ensures prolonged working of dry chains in dusty atmosphere.
