Polyurethane bushings

 

---

Polyurethane properties often surpass and replace use where ordinary rubber has traditionally been used in the past. The most important properties are:

Strong adhesion
The adhesion is very good against metal, plastic and other materials. Often used as a coating on rollers in various machines such as printing presses.

Elastic and dimensionally stable
Can be made soft and stretchy to hard and dimensionally stable. Small settlement/memory of the original form. Also retains its properties over larger temperature ranges -40 to + 80 ° C.

Durable and cushioning
Resistant to mechanical abrasion. Shock, sound and vibration damping.

High chemical resistance and weather resistant
Withstands solvents, oils and petrol, among other things. Also high resistance to UV radiation/sun.
