Customized performance systems

Desmodur® MDI-based systems for hot cast polyurethane elastomers

Polyurethane hot cast elastomers based on 4,4'-methylene diphenyl diisocyanate (MDI) are available in ether, ester and polycarbonate. They process at high temperature for components and molds. This range combines conventional MDI based systems as well as amine cross-linked MDI based systems, known as Desmodur® MAX.

MDI-based systems

Desmodur® MDI-ether systems are used in hydraulic seals, hydrocyclones, flotation cells, timing belts, textile rollers and other applications. They offer:

  • Good abrasion resistance
  • Excellent hydrolysis resistance
  • Resistance to microorganisms
  • High resilience
  • Potential suitability for food contact


 
Desmodur® MDI-ester systems are used in scrapers, couplings, doffers, squeegees, screens, vibratory bowls, and many other demanding applications. They possess:

  • Good abrasion, tear and chemical resistance
  • Excellent dynamic properties and resistance to internal heat build up
  • Potential suitability for food contact

Desmodur® MAX amine cross-linked MDI ester and ether combines the performance of MDI-based systems with easy processing and good flow-ability. Desmodur® MAX provides superior mechanical properties:

  • High elongation
  • High resilience
  • Excellent tear and tear propagation resistance
  • Exceptional abrasion resistance and hydrolytic stability
  • Low compression set
