Materials

PU

Polyurethane is a material that has the elastic properties of rubber. The proportion in its composition (diisocyanate, polyol, chain extender) is determined by its properties. This material is characterised by a strong mechanical resistance, good wear resistance, high elastic modulus, good flexibility and a very good ozone and oxidation resistance.

Chemical resistance Pure aliphatic hydrocarbons (propane, butane)
Mineral oils and greases
Silicone oils and greases
Water up to +50°C
Compatibility issue Ketones, esters, ethers, alcohols and glycols
Hot water, steam, alkalis, amines and acids
Temperature range -30°C/+90°C
