Polyurethane (pu)

Polyurethane (PU) are a large family of polymers with widely ranging properties and uses all based on the reaction product of an organic isocyanate with compounds containing a hydroxyl group. Polyurethanes may be thermosetting or thermoplastic, rigid and hard or flexible and soft, solid or cellular with great property variances.

Polyurethane is an incredibly resilient, flexible, and durable manufactured material that can take the place of paint, cotton, rubber, metal, and wood in thousands of applications across all fields. Polyurethane might be hard, like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber wheels, or sticky like glue. Since its invention in the 40s, polyurethane has been used in everything from baby toys to airplane wings, and continues to be adapted for contemporary technology.

Some polyurethane is categorized as an elastomer. It has elastic properties while maintaining some rigidity, such as in the wheels of a dolly that absorb shock but don't compress too much. It can be extremely flexible when used as a foam insulator in construction or a foam cushion in upholstery. It can be deformed over and over and still maintain its original shape; in other words, it has a structural memory. Elastomers have made our home and work environments warm and comfortable. This versatility results from the unique structure of PU that results in high resilience, good compression set, plus resistance to impacts, abrasions, tears, weather, and even hydrocarbons. PU offers flexibility without the use of plasticizers as well as a broad range of hardness and high elasticity.
