HD-DB-150 High Temperature Resistant Rigid PU Foam Systems

Beijing Maohua PU Building Materials Co., Ltd.

HD-DB-150 is double-component PU foam system specially designed for high temperature resistant(150℃) thermal insulation. B-component is modified polyisocyanate(MDI), while A-component is made up of polyether polyalcohol, blowing agent,catalyst and stabiliser,etc. It is featuring of long-term high temperature resistant(150℃), applied to the pipe insulation and disinfection cabinet. It has two kinds of brands.

*  HD-DB-150F, rapid reaction, applied to handy injection with a little input each time.

*  HD-DB-150S, slow reaction, applied to large sized pipe with much input each time.
