HIGH-TEMPERATURE RIGID POLYURETHANE SPRAY FOAM FOR PIPE INSULATION |
摘要 |
The present invention provides a rigid polyurethane spray foam, which is made using cyclopentane as the blowing agent and which is useful for pipe insulation because of its ability to withstand high-temperatures (>250°F). The inventive foams may be sprayed with existing foam spraying equipment because the foams are reacted at about a 1:1.25 polyol to isocyanate ratio.
