Product Description
SY-Panel 145 blend polyols is a compound which consists of polyether polyols, surfactants, catalysts and flame retardant in a special ratio. The foam has good thermal insulation property, light in weight, high compression strength and flame retardant and other advantages. It is widely used to produce sandwich plates, corrugated plates etc, which applies to make cold stores, cabinets, portable shelters and so on.
