Urethane, technically referred to as polyurethane (or PU), is an elastic polymer, or elastomer, containing urethane carbamate links that may be fabricated or molded into low-density flexible foam, low-density rigid foam, soft solid elastomers (gel) and hard solid plastics. In addition, polyurethane manufacturers have an advantage over plastic, rubber and metal manufacturers due to the many advantages urethane has over those materials. Read More…

More Polyurethane Companies
Polyurethane has higher abrasion, cut, tear, oil, ozone and radiation resistance, greater load bearing ability, broader hardness range and better colorability than rubber, which enables polyurethane manufacturers to do more with their product then other raw material manufacturers.
As compared to metal, polyurethane has better noise reduction and resilience, greater abrasion, corrosion and impact resistance, more flexibility and is less costly to fabricate. Different polyurethane products typically produced by polyurethane manufacturers include cellular suspension units, press tool blocks, grommets, bearings, shock absorber bushes, rope pulley linings, conveyer belt scraper blades, abrasion resistant strips and hydraulic seals.
With such a broad range of products, polyurethane suppliers are able to meet demands for many industries including civil engineering, mining, industrial manufacturing.
Polyurethane manufacturers offer a wide variety of molded urethane services and processes. One process is open polyurethane casting, in which the pre-polymer and curative are heated and mixed together, poured into an open cavity and cured without the application of pressure.
Closed polyurethane casting, or injection molding, is another process in which the pre-polymer and curative are heated and mixed together, then injected into the closed cavity through small holes. Able to be molded through either process, the raw materials of polyurethane exist in a liquid state, which allows for easy mixing and measuring in preparation for molding.
Raw materials react with one another to form a pre-polymer, then during the urethane molding process, a curative is introduced to the pre-polymer in order to complete the polymeric transition. Accelerated by heat and/or pressure, the mixture is poured into a mold cavity and cured to form the final polymer.
The molding process is only the beginning; next are fabrication processes used to produce products. Many polyurethane casters offer custom fabrications processes for unique applications.
In addition, the cost of polyurethane molding is on par with the cost of rubber and typical polymer molding, giving polyurethane manufacturers an economic advantage as well.
