Cast PU elastomers

CAST POLYURETHANES : VERSATILE WITH REMARKABLE PROPERTIES

Elastomers for a whole world of applications

In the late 40s, a new category of polymers called polyurethanes was developed, based on Bayer invention in 1937. They come from the reaction of diisocyanates, long chain polyols and short chain extenders. Their processing proved to be a flexible method of producing customised elastomers with adjustable properties. This enables the manufacture by unit or in series of either small or large parts with substantial savings in terms of moulds and equipment compared with other plastics.

Flexible processing methods for most production environments

Cast polyurethanes achieve hardnesses on a wider range than any other elastomer and exhibit outstanding physical properties such as: abrasion, by far better than steel; tear resistance, superior to these of many other elastomers; resilience; load bearing capabilities. Through the years, their special properties made them indispensable in more and more fields replacing other materials with lower properties.

Applications

There are numerous applications of cast polyurethane. Cast PU parts can be found in almost all kinds of sectors and our formulations are adapted to numerous industrial fields, like in-line skate wheels, concrete manufacturing, quarries sorting screens, marine applications, etc.
