Skerui: Low-cost high-strength polyester spraying composite material solution

SKR-450A is a modified phthalic anhydride polyester polyol. Because 450A has higher functionality and benzene ring content, it is especially suitable for rapid prototyping systems, especially for the field of polyurethane spray insulation and cold insulation. 100% polyester In addition to significantly improving the flame retardancy of the foam, the added amount still maintains high dimensional stability, and at the same time the cost is greatly reduced.

This product can be used in the field of polyurethane rigid foam, covering polyurethane spraying, PIR sheet, refrigerator, solar energy, pipe insulation, and various pouring high and low density foam materials and packaging foam.
