Urethane Additives


Momentive offers one of the most trusted and diverse urethane additive product lines in the industry. Our selection includes numerous silicone stabilizers and tertiary amine catalysts, as well as organic-based foam property modifiers. Our additives may be essential ingredients in polyurethane foam processing, including flexible and rigid foams found in appliances, automotive interiors, furniture, bedding, construction materials, insulation, electronics, footwear and more.

For more than 50 years, our Niax* brand has enabled the efficient and consistent production of a wide array of foam products. Niax additives for flexible polyurethane foam feature open and fine cells, highly effective fire retardancy, improved density distribution and low volatile organic compound (VOC) emissions. Niax additives for rigid polyurethane foam may provide improved blowing agent compatibility, solubility and miscibility, as well as enhanced thermal conductivity, dimensional stability, flow, leveling and adhesion promotion.

Our Geolite* modifiers help flexible slabstock foam producers broaden their offering of foam grades, including softer foams. This product family typically permits more water use in processing slabstock foam, allowing producers to economically eliminate or substantially reduce the use of auxiliary blowing agents. Foam producers can also achieve softer foams when using Geolite softening and stabilizing additives with CO 2 processing equipment. 

We also offer Fomrez organometallic tin catalysts for specialty applications. These catalysts can offer varying degrees of delayed action and hydrolytic stability to meet our customers' processing needs.

Learn how our urethane additives can boost the efficiency of foam processing and deliver reliable, repeatable performance.
