ADDSiL™ 11220 silicone surfactant is a non-hydrolytic polyether polydimethylsiloxane copolymer with high activity.
It is designed for HCFC-141b and cyclopentane blown polyurethane foams; it provides strong nucleation and low thermal conductivity.
Transparent viscous liquid
< 0 °C
pH (1% water solution)
ADDSiL™ 11220 silicone surfactant for PU rigid foam provides very good fluidity during the entire foaming process in the reaction system and produce homogeneous density distribution.
ADDSiL™ 11220 silicone based surfactant provides excellent nucleation ability. Very fine cells and flow can deliver foams with constantly low thermal conductivities in all areas of the foamed refrigerator cabinet.
The recommended concentration of this product is 2% to 3% of polyol (php).
ADDSiL™ 11220 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™ 11220 is supplied in net weight 200Kg steel drum or 1000Kg IBC tote.
When stored at ambient temperature in the original unopened packing, ADDSiL™ 11220 has a shelf life of 12 months from the date of production.
