Surfactants for Rigid Foam
In rigid foam production, suitable surfactants are selected to meet the requirements of emulsification / nucleation / flow and density distribution.
SI8900
SI8900 provides very good stabilization and extremely fine cells,working in the application of construction panel, spray foam, pipe insulation and appliance.
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.
SI89201
SI89201 is especially designed for refrigerator formulations, providing excellent foam surface quality by reducing voids and very low K value.
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.
SI89443
SI89443 is specially designed for panel production, especially for the production of continuous metal faced panels.
