Product Description
polyol blend is designed for all-water-blown system. It is mainly used to produce thermal insulation layer of various media transmission pipelines, which has excellent thermal insulation properties, mechanical strength, aging resistance, and low water absorption. By reacting this polyol blends with polymeric MDI, such as M20S and Wanhua's PM-200, the foam produced has good fluidity, convenient construction and strong operability, and the finished foam has excellent thermal stability and adhesion, and excellent dimensional stability.
