MDI polyester HP

Product information

The MDI polyester HP is a 3 component system. This system has some clear performance advantages over some of the more traditional high performance polyurethane elastomers. The polyurethane elastomer exhibit excellent physical properties, including good tensile strengths, high resilience and excellent wear characteristics as well as outstanding hydrolytic stability. There are also clear advantages in terms of processing, including low viscosity at processing temperatures and lower chemical hazards when handling the compounds.

MDI based products have lower isocyanate odour than similar TDI types and have superior hydrolysis resistance and often have higher resilience.

MDI polyester HP is available from shore 55A up to 95A.

Difference MDI polyester HP and MDI-PTMEG-series

POLYESTER BASED: The MDI polyester HP is recommended for applications where parts undergo dynamic stress, i.e they incur lower heat build-up. High resilience, low temperature performance and resistance to water (hydrolysis). The MDI polyester HP also is suitable for FDA applications.

POLYETHER BASED: The MDI-PTMEG is recommended for applications where parts need to have superior cut, tear, abrasion, oil and solvent resistance.
