CertiPUR-US~? Compliant MDI Flexible Polyurethane Foams

摘要

Flexible polyurethane foams, particularly visco-elastic foams, have seen increased applications in the bedding market in recent years. In particular, the application of visco-elastic polyurethane foams has not only enjoyed tremendous growth, but also seen positive recognition and acceptance from consumers. On the other hand, consumers are becoming better informed and would like to understand the materials inside the mattresses that they buy and use. The voluntary CertiPUR-US~? program was developed to address consumer concerns, such as durability, content and indoor emissions. Huntsman has developed a unique MDI-based flexible polyurethane foam technology, which offers premium-grade polyurethane foams that meet or exceed CertiPUR-US requirements. These innovative approaches will enable slabstock foam producers to more fully meet the needs of the market and regulatory requirements. In addition, our new MDI-based technology also offers advantages over traditional TDI-based technology. These advantages include simple and robust processing, fast curing, easily tunable densities and reduced catalyst requirements. This paper demonstrates that high-quality MDI visco-elastic can be readily produced with outstanding properties. These improved properties include superior compression set, compliance with California Technical Bulletin 117 Vertical Fire Tests and low emissions as required by the CertiPUR-US program.
