PUPolyurethane
Polyurethane can take on a very wide range of properties by changing the raw materials or their mixing ratio and by using modifiers such as glycols and diamines. This versatility is why it is used for soft and hard products, rubber elastomers, coatings, adhesives, synthetic leather and sealants. Hardness ranges from 30 to 98 Shore A, and it offers excellent wear resistance, mechanical properties and oil resistance.
