Thermoplastic Polyurethane TPU Desmopan 385E (Covestro)

Description


Desmopan 385E is an ether-based thermoplastic polyurethane (TPU) with 50% recycled content. The material demonstrates high wear resistance, flexibility over a wide temperature range and high elasticity across the entire hardness range. It is soft, requires no plasticizer and provides excellent resistance to oils, greases and solvents, as well as to weathering and high-energy radiation. Desmopan 385E delivers high mechanical strength and a reduced carbon footprint without compromising quality or performance. It is suitable for processing by extrusion and injection molding.


Advantages:

  • High wear resistance
  • Flexibility and elasticity
  • Resistance to oils and solvents
  • High mechanical strength
  • Resistance to weathering and high-energy radiation

Applications:


Desmopan 385E is used across various industries thanks to its unique properties. Main application areas include:


Films and unreinforced hoses: provide flexibility and chemical resistance.

Screen elements and engineering components: high mechanical strength and wear resistance make the material ideal for these applications.

Rigid-flexible composite systems: suitable for use in flexible and rigid components, ensuring reliable material bonding.
