Northstar Polymers SAI-1 Low Viscosity Variable Ratio Polyurethane Gel

SAI-1 is custom formulated polyurethane gel material to yield very soft elastomer gel material from low viscosity components at room temperature. This material is variable mixing ratio so that the user can change the properties of the product simply by changing the same combination of part-A and part-B liquid components. The material does not contain plasticizer so that it will not leach plasticizer to affect the other plastic material surrounding the gel part, or to cause a severe hardness change in long term use. Possible application for this material includes potting and encapsulation of optical cables, manufacturing of puncture-free tire layer, cushioning and padding parts by open-cast molding, and many other custom applications. This material is not designed to be cast directly into flexible film casings.Information provided by Northstar Polymers.
