ADDSiL™ 11630 surfactant is a non-hydrolysable polyether polydimethylsiloxane copolymer. It is designed for rigid polyurethane foaming system with blowing agents like 245 /Cyclopentane /LBA/Ecomate, as well as some mixture blown agents like LBA/CP.
Transparent viscous liquid
pH (4% water solution)
ADDSiL™ 11630 is designed for panel and appliance system production. It provides good emulsify and nucleation ability therefore excellent thermal conductivity and very fine density distribution of final foam.
ADDSiL™ 11630 silicone surfactant for PU rigid foam helps to get lower K value performance as fine cell can be made during foaming. It also improves foam density distribution basing on excellent fluidity.
The recommended concentration of this product is 2% to 3% of polyol (php).
ADDSiL™ 11630 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™ 11630 is supplied in net weight 200Kg steel drum or 1000Kg IBC tote.
When stored at ambient temperature in the original unopened packing, ADDSiL™ 11630 has a shelf life of 12 months from the date of production.
