Polyurethane Properties and Design Considerations

Please use this Design Guide to explore the wide potential of polyurethane to solve your demanding challenges, and then contact us to help out with design, engineering, and production.

It’s a Rubber… It’s a Plastic… It’s a Polymer

Polyurethane is all of These!

Polyurethane bridges the performance gap between rubber and plastic.  Like all polymers, its performance comes from its molecular make-up. Depending on the chemistry formulation and the reaction process, polyurethane’s end-state performance is tailorable to meet exactly what you need.

Maybe you need a material that’s flexible and tough… Or perhaps you’re looking for something that is rigid yet impact resistant.  Polyurethane is both (and more)!  That’s why we say polyurethane is the Ultimate Engineering Material.

Countless Applications

Because of Three Key Advantages
abrasion

Polyurethanes have outstanding abrasion resistance, often outwearing corresponding parts made of metal, plastic, or rubber by a wide margin.

dynamic-load-bearing

Polyurethanes have an excellent load-bearing capability and exhibit deflection and recovery that far exceed plastic or metal.

complex-shapes

Creating complex shapes is no problem for polyurethane because we mold it in its liquid state.  Polyurethane can be permanently attached — or bonded — to metals, plastics, and composites during the molding process.
