FIRE RESISTANT FOAM INSULATION COMPOSITIONS

摘要

This invention relates to polyurethane foam insulation materials comprising cenospheres, a coal combustion waste by-product, a poly-isocyanate and petroleum and/or vegetable based polyols and/or post-industrial or post-consumer recycled polyester to produce polymeric foam insulation products useful in building materials and component products. The percentage of industrial waste product, recycled materials and sustainable vegetable based components used in the formulations support make this a green composition.
