Momentive to showcase wide variety of new Niax materials

Automotive: Niax moulded foam additives offer reduced volatile organic compound (VOC) emissions and fogging, weight reduction, high yield and easy transition between TDI and MDI systems. Niax Silicone L-3639, which can be considered for a wide variety of MDI-based formulations, typically provides a lower siloxane emission when compared to industry standards. Additionally, it offers wide processing latitude and has demonstrated good physical properties in many finished foam products.Niax Catalyst EF-150 is a non-fugitive reactive blow amine catalyst to consider for use in moulded foam applications. It offers a unique combination of low emission and delayed action properties providing lower force to crush, which can ultimately result in lower foam scrap during manufacturing. The product can also provide higher final foam hardness when compared to traditional catalysts, says the company. Furniture and bedding: Niax flexible slab foam additives offer multi-functionality while typically improving foam resilience, durability and sustainability. Niax Catalyst EF-350 is a low-fugitive balanced tertiary amine catalyst to consider for use in slabstock foam. According to MPM, it provides wider processing latitude when compared to traditional tertiary amine catalysts and it can dramatically reduce emissions from foam. Furthermore, Niax Catalyst EF-350 can reduce the emission of 2-ethyl-hexanoic acid (2-EHA) from foams.Niax Silicone L-2118 can be considered for TDI and TDI/MDI high resilience (HR) slabstock foam. When compared to industry standards, Niax Silicone L-2118 typically provides lower bottom voids in HR foam, improved top-to-bottom density gradient and a more uniform cell structure, says the company. Carpet and electronics: Niax speciality froth additives can offer requirements critical to niche applications, especially in carpet underlayment and electronics applications. Niax Catalyst LC-5630 typically provides a longer delay time with fast end-cure when compared to traditional catalysts, which results in good even flow. It is a thermally-activated catalyst for use in mechanical frothed foam. Appliance and construction insulation: Niax rigid additives offer foam formulators a wide portfolio of products to improve foam quality and properties. Additionally, the additives help solve processing issues: foam stabilisers can help reduce voids and produce finer cells; adhesion promoters, PIR curing additives and additives can aid with processing open cells foams. Niax Silicone Y-16206 is a surfactant that can be considered for panel application. It can contribute to improved FR performance while offering voids reduction and system compatibility.Niax Silicone Y-16130 can help produce low-defect foam used in high performance refrigerators, providing very fine and homogeneous cells with lower K factor and improved insulation, made with cyclo-pentane or in blends with HFC's and HFOs.
