TPU for Outsoles

Estane® TRX TPU

It's tough out there. Engineer to perform with TPU

Estane® TRX TPU (thermoplastic polyurethane) is making tracks as the innovative rubber replacement for outdoor, athletic and work shoe outsoles. Outsoles made from Estane TRX TPU provide outstanding benefits for both consumers and footwear designers.


  • Reduced labor costs via thermoplastic injection molding
  • Automated production possibilities versus traditional rubber outsole molding


  • Recycling* possibilities at outsole manufacturing and post with TPU (not available with thermoset rubbers)


  • Exceptional slip resistance with wet ground conditions

  • Excellent wear resistance against heat friction on the shoe outsole at room/high temperatures

  • Transparent outsole allows color freedom for novel design

  • Thinner TPU outsole improves flexible feeling and improves weight reduction
