PolyChim-2001 and PolyChim-2001/1 polyesters


   These polyesters are terephthalic-base saturated polyesters which contain catalysts, foaming agents, foam regulator, and antipyrens. These products are designed for manufacturing rigid foamed PU in production of cooling equipment, sandwich panels, foamed PU pre-formed insulation, decorative components for interior finishing and in civil construction.  

   Foamed PU formed based on these polyesters has very low thermal conductivity factor, it is environmentally safe, long-lasting, provides sound insulation, has low water absorption, and has good processability.
