Rigid Polyurethane Foam PUR

product description

Rigid PUR is a new thermal insulation material, with a high percentage of close area and low water absorption. The main raw materials are polyether/polyester and isocyanate, the additives contain flame retardants, stability and foaming agents. The gas in the closed cells come from the reaction of foaming agent, which makes PUR self-extinguishing. It’s often used as insulation in low temperature.
