Rigid Blend Polyether Polyols for Discontinuous Panels

DBC-402B

Product Introduction

DBC-402B blend polyols is a compound which consists of polyether polyols, surfactants, catalysts, foaming agent and flame retardant in a special ratio. The foam has good thermal insulation property, light in weight, high compression strength and flame retardance 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.
