TECHNOLOGY- MATERIAL SYSTEMS 

Polyethers are recommended for applications were parts undergo dynamic stress. ie. 
They incur lower heat build-up. They also have advantages in resilience, low temperature
 performance and resistance to water attack (hydrolysis). Polyethers also have lower 
viscosity and specific gravity.

Polyester based urethanes have superior cut, tear, abrasion, oil and solvent resistance.

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

TDI based products are less sensitive to moisture, have shorter demould times and lower cure temperature requirements compared to
