Our highest purity, lowest OH offering for polyurethanes
MODULAST PUR is a newly developed, high purity modifier designed primarily for use in reactive polyurethane systems, featuring the lowest residual hydroxyl levels available on the market. MODULAST PUR aids the polyurethane formulator by coupling unexpected properties—softness and strength—while providing exceptional compatibility and very low color development and odor.
While MODULAST PUR helps impart softness to polyurethanes, it does so with less efficiency than traditional dibenzoates such as MODULAST CLS. Combined with its high compatibility, this means that MODULAST PUR can be utilized at higher loading levels to achieve equal softness, providing the opportunity to optimize the overall cost of a polyurethane formulation.
