PolyChim-2002 polyester


   PolyChim-2002 is a terephthalic-base saturated polyester which contains catalysts, foaming agents, foam regulators, and antipyrens. This product is designed for production of spray type rigid foamed PU used as thermal insulation in residential and non-residential buildings and structures, and means of transport.  PolyChim-2002-based foam has good mechanical strength, excellent adhesion to substrate, short foam setting time.
