Triathane® Variable Hardness Polyurethane

 

"Solutions that add value instead of just cost"

This, 3 component, variable mix ratio polyurethane system was developed to provide processors with a convenient and less labour intensive method of achieving a range of cured hardness properties simply by combining the same urethane components in various pre-determined ratios. This urethane system eliminates the necessity of stocking and loading different products into the processing equipment every time a change in cured hardness is required. All the urethane components are low in viscosity and do not require heating to obtain suitable processing conditions. Unlike hot-cast type urethanes, there is no need to formulate and/or compound different products to change the cured hardness.

 

Although the system may be used in hand mixing (hand batching) processes, it is highly suitable and more efficient in applications employing automated dispense equipment. We found that the unique polyurethane dispense equipment, the "Hand Pour Machine", manufactured by the State Mix Company is very suitable for this purpose*.
