PU Additives for Appliances and Cold Chain

Improve Insulation and Quality to Enhance Appliances Performance Aesthetics

The Niax™ portfolio by Momentive includes innovative silicone surfactants, catalysts, and special additives for rigid polyurethane foams used in appliances. Appliance manufacturers face growing demands to comply with more challenging thermal insulation performance to meet energy labeling requirements, thus meeting consumers expectations. As a result, modern household appliances must be more efficient and long-lasting. Our products are designed to help manufacturers enhance insulation properties and efficiency across domestic, industrial, and commercial appliances, including freezers, refrigerators, water heaters, and discontinuous applications. 

Niax silicone foam stabilizers are compatible with a wide range of blowing agents, including HC and HFO, providing an excellent blowing agent solubility in the polyol blend. 
Niax silicones enhance the production of foams with exceptionally fine cells, ensuring uniform filling of complex cavities and delivering the thermal insulation needed to meet the highest energy consumption targets, even with the most challenging design requirements. They also contribute to a significant improvement in the aesthetics of domestic refrigerators and beverage display units.

Niax catalysts and special additives contribute to support productivity and durability by facilitating fast processing and enhancing the structural integrity of foam-filled appliances.

Domestic Refrigeration

Polyurethane foam is the preferred insulation material for appliance production due to its excellent thermal insulation properties. To achieve optimal results, Momentive’s silicone additives and catalysts play a vital role in enhancing polyol formulations. These advanced solutions enhance the foam’s flowability, allowing it to fully fill the intricate cavities of appliances like refrigerators. Additionally, they help maintain a fine cell structure and a smooth surface, eliminating voids that could lead to aesthetic defects.

Discontinuous Applications

Polyurethane foams play a crucial role in food preservation, providing exceptional thermal insulation for industrial applications such as refrigerated trucks, cold storage, wine coolers, supermarket freezers, water heaters, and pipe-in-pipe systems. Momentive’s silicones and catalysts enhance these foams by improving flow, ensuring uniform lambda values, achieving optimal density distribution, and minimizing voids. These enhancements deliver reliable performance across various demanding insulation technologies, supporting efficient temperature control and upholding high standards in modern refrigeration and storage solutions.
