ADDSiL™ 11090 silicone surfactant is a non-hydrolytic polyether polydimethylsiloxane copolymer. It is designed for HFC-245fa and the mixture blown polyurethane foams; it provides low thermal conductivities.
Transparent viscous liquid
pH (4% water solution)
ADDSiL™ 11090 silicone surfactants for polyurethane foam provide excellent nucleation ability. Very fine cells and flow can deliver foams with constantly low thermal conductivities in all areas of the foamed refrigerator cabinet.
ADDSiL™ 11090 silicone surfactant for PU rigid foam provides excellent compatibility in polyether polyol blends with pentanes avoiding additional haziness and phase separation.
The recommended concentration of this product provided by SiSiB is 2% to 3% of polyol (php).
ADDSiL™ 11090 surfactant will become hazy when stored at temperatures below 20°C and will solidify to a soft silicone wax at temperatures below 10°C. The product should be warmed to room temperature and stirred before use.
ADDSiL™ 11090 is supplied in net weight 200Kg steel drum or 1000Kg IBC tote.
When stored at ambient temperature in the original unopened packing, ADDSiL™ 11090 has a shelf life of 12 months from the date of production.
