Applications

PUR is a true Thermoplastic Elastomer (TPE) that can be used in plastic molding for a variety of applications, including:

  • Automotive
  • Building & Construction
  • Casters
  • Gaskets
  • Bushings
  • Soft Touch Grips & Handles
Advantages PUR is a unique plastic resin that offers a number of advantages, such as:

  • Combined Toughness & Durability of Metal with the Elasticity of Rubber
  • Can be Repeatedly Stretched without Permanent Deformation
  • Does Not Require Curing or Vulcanization
Disadvantages
  • Poor Thermal Capability
  • Poor Weatherability
  • Attacked by Most Solvents
  • Flammable
  • Utilizes Toxic Isocyanates
