Glass Reinforced Rigid TPUs Combine High Strength and Toughness

Desmoflex® compounds are reinforced rigid thermoplastic polyurethanes (RTPU) designed for high strength and toughness. These grades exhibit significant improvements in strength and stiffness, yet retain the important features of TPU, including: impact toughness, abrasion resistance, chemical resistance, and cold temperature performance. Desmoflex TPU compounds are ideal for structural applications intended for repeated use or that endure constant handling, like in housings for electronics or handles used in public transportation or for power equipment. Desmoflex has replaced engineering resins in these types of applications and offers additional benefits, including better vibration dampening characteristics and dry haptics for a nice feel. 

Characteristics of Desmoflex® R TPU Compounds


  • Excellent  impact toughness
  • Good  surface appearance
  • Excellent low temperature performance
  • Vibration dampening characteristics
  • Abrasion/wear resistance
  • Good Chemical and oil resistance<

Desmoflex TPU compounds can be ether or ester based, contain up to 30% glass reinforcement, and are available from 55 to 75 Shore D in black, natural, or custom colors. These materials are suitable for both injection molding and extrusion applications in a variety of industries.
