1.Products description:
BOLNFLEX elastomeric insulations are engineered and manufactured for HVAC and other industrial applications. With closed cell structure BOLNFLEX insulations effectively retard heat flow and prevent condensation when properly installed. The environmental friendly materials are manufactured without the use of CFC’s, HFC’s or HCFC’s. They are also formaldehyde free, low VOCs, fiber free, dust free and resistant to mold and mildew.
On the basis of the elastomeric foam with closed-cellular structure, high quality flexible insulation product designed for insulating in the field of heating, ventilating, air conditioning and refrigerating(HVAC & R). And provides efficient method of preventing undesirable heat gain or loss in chilled water systems, cold and hot water plumbing, refrigerated pipes, air conditioning ductwork and equipment.
