Surfactants for Rigid Foam

In rigid foam production, suitable surface foam surfactants are selected to meet the requirements of emulsification / nucleation / flow and density distribution. According to the different foaming agent systems and specific applications, we give the following recommendations:

SI8900

SI8900 provides very good stabilization and extremely fine cells,working in the application of construction panel, spray foam, pipe insulation and appliance.

View Details

SI8906

SI8906 is specially designed for  polyester polyol system, working good in PIR panel, spray foam, pipe insulation.

SI8921

SI8921 has excellent emulsification and better solubility with blowing agents, working good for construction panel, spray foam, pipe insulation.

SI8972

SI8972 provides a sufficient dimensional stability and a very fine cell structure, especially suitable for OCF, also working well for panel production.

View Details

SI89201

SI89201 is especially designed for refrigerator formulations, providing  excellent foam surface quality by reducing voids and very low K value.

View Details

SI86496

SI86496 can mix with all commonly applied rigid polyols, especially for the production of continuous metal faced panels.

SI89108

SI89108 provides very efficient emulsification in insulation foams, such as in cold storage applications and refrigerators.
