  • 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).

Packing and Storage

  • 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.
