PolyChim-2001/3 polyester PolyChim-2001/3 polyester is a terephthalic-base saturated polyester which contains catalysts, foaming agents, foam regulators, and antipyrens. This product is designed for manufacturing pre-insulated pipes.
PolyChim-2001/3- based foamed PU has very low thermal conductivity factor; it is environmentally safe, long-lasting, has low water absorption, and good processability. | Recommended formulation | Parts by weight | PolyChim-2001/2 polyol
