Enquire About re-flex

Thermoplastic Polyurethane (TPU) is a thermoplastic elastomer used to produce plastic characterised by toughness, elasticity, transparency, and resistance to oil, grease and abrasion. TPU is a unique, durable versatile performer. It is lighter than metal, has excellent cold temperature flexibility, greater abrasion resistance than rubber, bonds easily to surfaces, and can also be used as a malleable engineering plastic or as a replacement for rubber or cast urethane.

RE-FLEX is Townsend Chemicals comprehensive, highly versatile range of Thermoplastic Polyurethanes grades. These linear polyurethanes are available in a wide hardness range. There are 2 main types of TPUs available to accommodate the various applications and environmental performance criteria. One type is based on a polyester polyol and performs where resistance to oil and grease is required. The other type is based on a polyether polyol and is suited to applications where humidity levels are constantly high.

  • Polyester TPU provides excellent rebound and toughness. Compatible with PVC.
  • Polyether TPU offers low temperature flexibility and is ideal for wet environments.

RE-FLEX TPU elastomers are made without using plasticisers and are therefore used as an environmentally friendly alternative to PVC without compromising flexibility.

Features


  • Abrasion, chip, tear, and impact resistant.
  • Chemical, fuel, oil, grease and solvent resistance.
  • Tensile strength, tough.
  • High elasticity and elongation.
  • Hydrolysis stability.
