Rigid Foam Polyurethane Additives

Niax Additives For High Performance Rigid Polyurethane Foam

Niax™ additives for rigid polyurethane (PU) foam provide advanced formulation optimization for a wide range of applications, improving the performance and versatility of foam products. ​

Niax silicone surfactants are specifically engineered to enhance foam structure with fine cell formation, superior thermal conductivity, and improved compatibility with various blowing agents. These surfactants also boost miscibility, dimensional stability, and flow, reduce surface voids, and can help to ensure high-quality foam production.​

Additionally, Niax catalysts support efficient productivity in both polyurethane (PUR) and polyisocyanurate (PIR) foam systems, enabling precise control over the reaction profile and shelf-life. The Niax additive portfolio also includes adhesion promoters, cure promoters, and specialized silicones for open-cell rigid foams, expanding formulation possibilities and delivering robust, high-performance foam solutions.

Silicone Surfactants

Momentive’s silicone surfactants are expertly engineered to meet the evolving needs of the polyurethane industry. Our diverse range of high-performance silicone solutions enables superior polymer properties across a wide variety of final applications, particularly in rigid polyurethane foams.​

As the polyurethane industry faces stricter regulations and higher industry standards, Momentive is dedicated to continuous innovation. Our team of scientists is focused on developing sustainable solutions that improve insulation performance, enhance cell dimension and isotropy, and deliver exceptional surface quality in rigid foams. With a growing portfolio of high-purity silicone surfactants, we are committed to advancing the future of polyurethane manufacturing.
