Polyurethane is a unique engineering material which offers the elasticity of rubber, toughness and durability of metal.
Polyurethane Elastomers are extremely versatile materials and this has been the key to their widespread applications. This flexible engineering material is available in Polyurethane Sheet, Rod, Tube, and Custom Cast Products.
Parts made of polyurethane will often outwear other materials by a margin of 5 to 50/one 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 Ibs. /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 urethanes are used to replace rubbers 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.
Polyurethane has excellent electrical insulating properties and is used successfully in many moulded wire and cable harness assemblies.
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 pronounced until much lower temperatures are obtained.
