Polyurethane Foam

Siltech Corporation develops, manufactures and markets a full line of high-quality organo-functional silicone surfactants and related specialties for use in formulating polyurethane foams.

Our silicone surfactants products, known as the SILSTAB series, are used in a variety of polyurethane applications, including rigid foams, flexible foams and elastomers.

Siltech’s silicones are manufactured in Ontario, Canada. Each of our state-of-the-art facilities are equipped with dedicated large-scale reactors utilizing our novel hydrosilation manufacturing process technology. To ensure the consistent production of the highest-quality products, we employ advanced in-process controls to prevent variations.

At Siltech’s manufacturing site, our pilot plant facilities also produce experimental silicone surfactants and smaller quantities to meet our customers’ unique requirements.

We also have an advanced analytical laboratory, which features the latest instrumentation. Finally, Siltech’s technical service laboratory is equipped to completely evaluate the performance of our products in various polyurethane foams.

We are proud of Siltech’s extensive products range as well as our capability to supply products that are specifically tailored to our customers’ needs. We are enthusiastic about our ability to provide knowledgeable technical service and to remain in the forefront of silicone technology.
