Fire Retardent PP Duct Pipe

Fire retardant polypropylene duct is ideal for hoods and duct systems answering the problems of in-plant safety departments. Corrosive and toxic fumes are removed safely and down time is eliminated as the fire retardant polypropylene resists corrosion. Fire retardant polypropylene can attain a V-O rating according to UL-94 test for flammability of plastic materials. The incorporation of additives such as organic Bromine or Antimony compounds gives the PPS the fire retardant resistance. PPS is chemical and solvent resistant, has a hard surface and low moisture absorbency. Its temperature resistance is up to 100°C (212°F). The material is easily hand welded or fused like normal polypropylene. Care should be exercised in outdoor applications due to limited outdoor weathering resistance.
