The Aptane® PFS product portfolio includes a range of two component polyurethane pour or injection foam systems with densities and mechanical properties designed to suit the requirements of any application. The two main types of pour foams are low density pour systems and high density pour systems.
Aptane® PFS low density pour foam products have been used on pre-insulated pipeline sections, valve boxes, flanges and joints on pipeline systems in LNG and chemical plants. Aptane® PFS pour foams can be applied in-situ for valve boxes, joints and repair work.
Aptane® PFS high density pour foam products have been used in pipe supports where high compressive strengths, high durability as well as insulation performance are critical. These high density pour foams can be supplied to any specified density, typically the densities would be in the range of 160 – 500 kg/m³.
All of the Aptane® PFS series products are HCFC free. Aptane® PFS pour foams have met the stringent specification requirements expected by specifiers and engineers when designing chemical and gas processing plants for decades. Aptane® PFS pour foams can be designed to meet the individual requirements of each project. Typical properties of the Aptane® PFS product range are detailed in the table below.
