Injection Molding Resin-TPR
Dec 28, 2017

Injection Molding Resin: TPR

     TPR, or thermoplastic rubber—also known as TPE (thermoplastic elastomer)—is a class of copolymer materials or a physical mix of materials, such as a plastic and a rubber. TPR materials exhibit certain physical characteristics of both rubbers and plastics, as well as both thermoplastic and elastomeric properties. TPRs are well suited to processing via injection molding.

Properties of Thermoplastic Rubbers

  • High flexural fatigue resistance

  • Good tear and abrasion resistance

  • Good dielectric properties

  • Outstanding resistance to weathering and chemicals

  • High impact strength

  • Elasticity similar to cross-linked rubber materials

  • Available in a wide range of durometers, from 20 Shore OO to 85 Shore D

  • Broad temperature range: -30°C to 140°C (-22°F to 284°F)

  • Combine the look, feel, and elasticity of thermoset rubber with the processability of plastic

  • Recyclable
