Polyurethane foam
Polyurethane foam is a type of foamed plastic with cells filled with refrigerant or carbon dioxide. PUF consists of two components: А – polyol, B – isocyanate. The application has 3 stages: applying – foaming – build-up of a homogeneous thermal insulation layer. The advantages of PUF are: seamless application, operation temperature from -150 to +220 deg. C, additional strength of the pipeline structure due to rigidity.
