TPU for Outsoles


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

ESTANE® TRX TPU (thermoplastic polyurethane) is making tracks as the innovative rubber alternative 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
