PolyFoam System CF-200
Gaco Western's PolyfoamTM CF-200 is a zero ozone depleting liquid pour system for general use in cavity fill applications. It is co-blown with HFC and water and cures to a low density rigid polyurethane closed cell foam. This system is specially formulated to be free of scorch when poured in relatively large masses.
TYPICAL PHYSICAL PROPERTIES
Properties shown are for materials processed under laboratory conditions. The components were blended with a high speed mixer, poured into a container and cured at room temperature.
