Silicone Surfactants for Rigid Foam

Reliable solutions bring quality, performance and innovation

Understanding how silicone surfactants interact with rigid foam application systems is critical to your success. When you choose silicone surfactant from OSiC, our team will work with you to ensure that you understand not only how the surfactant affects the rigid foam formula, but also know how to maximize the ability to create the required foam.

OSiC silicone additives can be used in many rigid foam applications, including:

· PUR / PIR insulation system
· Various foaming agent systems, including water and hydrocarbons
· Household appliances and refrigeration and thermal insulation system
· Spray foam
· Cast in place
