SFS – Spray Foam Systems

The Aptane® SFS portfolio includes a range of two component spray polyurethane foam systems with densities and mechanical properties designed to suit the requirements of any application. These spray foam products have been used on pre-insulated pipeline sections for LNG plants, and have also been applied in-situ for LNG storage tanks. All Aptane® SFS series products are HCFC free.

Aptane® SFS spray foams continue to meet the stringent specifi cation requirements expected by specifiers and engineers when designing chemical and gas processing plants.

Aptane® SFS spray foams can be designed to meet the individual requirements of each project.

Typical properties of the Aptane®SFSproduct range are detailed in the table below.
