EU/AU (polyurethane rubber, polyester urethane)

This is a synthetic rubber, which contains urethane groups in the main chain, and it is the most commonly used polymer in the manufacture of foam. It is air-permeable and therefore returns to its original condition after the mechanical stress ceases. Its main characteristics are good heat insulating capacities and sound absorption.


upholstery, insulating, rollers for dyeing, parts with a high degree of wear, seals with high hydraulic pressure.


  • excellent resistance to wear and mechanical stress,
  • good resistance to changing weather conditions,
  • excellent tensile strength.


  • poor resistance to water, alkalis, high temperatures.

Temperature resistance: from - 30 °C to 120 °C.

Hardness: 55 to 90 Shore A.
