New Polymer Polyol for Combustion Modified High Resiliency Foams

摘要

Dow has recently developed a new polymer polyol with intrinsic flammability performance for high resilience and combustion modified high resilience flexible polyurethane foams. The polyol can be used to produce a wide range of foam densities with hardness up to 400 N in both standard and flame retardant grades for BS 5852 (Crib 5). Foams can be produced with a broad processing latitude, resulting in excellent foam physical properties such as high resilience, low compression sets and dynamic fatigue hardness loss. Foams required to meet British Standard Furniture and Furnishings Fire Safety Standard BS 5852 can easily be produced using melamine, TCPP or a synergistic combination of both with significantly reduced levels of flame retardants in comparison to foams prepared using styrene acrylonitrile (SAN) copolymer polyol (CPP) technology. The performance and versatility of this new technology means that a single polymer polyol can be used to produce the entire product range without the addition of other flame retardant polyols or high solids SAN CPP. This paper demonstrates the versatility of this polyol via an overview of foam grades, physical properties and flammability performance.
