Polyurethane: EU Polyether Urethane

General Purpose EU Polyurethane rubber is notable for its combination of hardness with elasticity, outstanding abrasion resistance and tear strength. Elastomeric urethane rubber, not to be confused with thermoplastic polyurethane, is often referred to as the "millable gum" urethane. Polyurethane is a moderately expensive material whose use is usually limited to applications that require its outstanding physical properties. Common end use applications are industrial seals, Air Guns, Paintball Markers, pneumatic applications, and other high dynamic applications.

Polyurethane (EU) Recommended uses:

  • Mechanical Applications
  • Wear Resistance
  • Pure aliphatic hydrocarbons (propane, butane, fuel)
  • Mineral oil and grease
  • Silicone oil and grease
  • Water up to 125°F (50°C) (EU type only)
  • Ozone and aging resistant.

  • Ketones, esters, ethers, alcohols, glycols
  • Hot Water above 40°C and Water Vapor
  • Dilute Alkalis and Acids
