Rigid Foam Systems

Fundamentally these systems are produced for isolation purposes. Foam systems produced for filling and packaging purposes are also low density foams.

Polyol system and polymeric isocyanate mix enlarges and makes a rigid foam by the help of a blowing agent. The foam produced has a 92% closed cell structure and has a rigid structure because of this they are called rigid foams. They are good thermal isolators. For this reason they are mainly used as heat isolators.

The thickness of equivalent isolation materials to 50mm Polyurethane foam;

Lambda (λ) is the heat transferring constant. Lower figures mean that heat isolation is better.

As it can be seen from here it is really hard to find a competitor to polyurethane foams in terms of isolation.
