WHY IS POLY URETHANE “PU” BETTER
Parts made of polyurethane will often outwear other materials when severe abrasion is a factor. It has been proven to be vastly superior to rubber plastics and metal in many applications.
Oil and Solvent Resistant
Polyurethane has excellent resistance to oils, solvents, fats, greases and gasoline.
Load Bearing Capacity
Polyurethane has a higher load-bearing capacity than any conventional rubber. Because of this characteristic, it is an ideal material for load wheels heavy duty couplings, metal-forming pads, shock pads, expansion joints and machine mounts.
Tear-strength ranges between 500-100 lbs/linear inch, which is far superior to rubbers. As a result, urethane is often used as drive belts, diaphragms, roll covers, cutting pads, gaskets and chute liners.
Polyurethane has outstanding resistance to oxygen, ozone, sunlight and general weather conditions.
Excellent Noise Abatement Properties
The hard urethanes are now being used as gears in products where engineers desire sound reduction. The soft urethane are is used to replace rubber for improved sound/vibration dampening.
Most formulations offer extremely high flex-life and can be expected to outlast other elastomer materials where this feature is an important requirement. Dust boots, bellows, diaphragms, belts, couplings and similar products are made from urethane for this reason.
Heat and Cold Resistant
Continuous use above 225°F is not recommended nor is urethane recommended in hot water over 175°F. At low temperatures, polyurethane will remain flexible down to – 90°F. A gradual stiffening will occur at 0°F, but will not become pronounce until much lower temperature are obtained.
