Thermoplastic Elastomers (TPES)

Thermoplastic elastomers (TPE) were developed and introduced in the 1960’s. TPEs are copolymers of thermoplastics and rubber. These polymer chains are highly attracted to each other and form crosslinks as the crystallise together. These materials therefore behave like elastomers but have the added benefit that they do not require vulcanisation.

Key Properties of Fluorocarbon Rubber:

  • Do not need to be vulcanized
  • Generally, they have faster cycle times than thermoset rubber
  • Elasticity in a limited range of temperatures
  • Ease of recycling

Drawbacks:

  • Relatively high cost
  • Melt at high temperatures

Operating Temperature Range: -40 to +120 °C

Typical applications:

  • Footwear soles
  • Toys
