Material Selection Guide
POLYURETHANE (AU, EU)
Polyurethane elastomers, as a class, have excellent wear resistance, high tensile strength and high elasticity in comparison with any other elastomers. Permeability is good and comparable with butyl.
Heat resistance:
- Up to approximately 82°C (180°F)
Cold flexibility:
- Down to approximately -40°C (-40°F)
Chemical resistance:
- Pure aliphatic hydrocarbons (propane, butane)
- Mineral oil and grease
- Silicone oil and grease
- Water up to 50°C (125°F)
Not compatible with:
- Ketones, esters, ethers, alcohols, glycols
- Hot water, steam, alkalis, amines, acids
