Rigid PU Foam Pipe Insulation
The rigid PU foam pipe insulation is comprised of system polyol and isocyanate. System polyol is the mixture of polyol, water, silicone surfactant, catalyst, and additives. It is developed for CFC free blown rigid foam insulation. You can choose the HCFC-141B or all-water-blown based foaming system.
The pipe produced by HCFC-141B blown system polyol has passed pipe anti-aging test per CJ/T114-2000 and creep test per EN253:2003.
Product Performance
This product has the characteristics such as high compressive strength, good dimensional stability, and low heat conductivity coefficient. It is applicable for different production conditions, for instance high or low pressure foaming machine, manual foaming, etc.
Remark
CJ/T114-2000: Preformed directly buried insulating pipes for polyurethane [PUR] foamed-plastics and high density polyethylene [PE] protect pipes
EN253:2003: District heating pipes - Pre-insulated bonded pipe systems for directly buried hot water networks - Pipe assembly of steel service pipe, polyurethane thermal insulation and outer casing of polyethylene.
