Product Details

XH-1686 foam stabilizer is a Si-C bond type of polysiloxane polyether copolymer. This is a versatile foam stabilizer used for the production of polyurethane rigid foam plastic, it has been originally developed for HCFC, water and hydrocarbons blown polyurethane foams, delivering very good foam stabilization and extremely fine celled foam; however industrial experience has demonstrated that it may also be used as a general-purpose surfactant for other rigid foam applications.

Key Features and Benefits

• Current applications for refrigeration, lamination and pour in place foam applications with hydrocarbons and water co-blown systems.

• Provides extremely fine, regular foam structure delivering foams with top thermal insulation performance.

• Uniform density distribution of the molded finished product is ensured.
