Top quality epp foam packing electrical insulating material

 Top quality epp foam packing electrical insulating material           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.   2.Products Features: 1) Product structure: closed cell structure 2) Excellent ability to prevent the spread of flames 3) good ability to control heat release 4) Flame retardant B1 level 5) Easily install 6) Low thermal conductivity 7) High water permeability resistance 8) elastomeric and flexible material , Soft and anti-bending 9) Cold-resistant and heat-resisting 10) Shake reduction and sound absorption 11) Good fire-blocking and water proof 12) Vibration and resonate resistance 13) Beautiful appearance, easy and fast to install 14) Safety (neither stimulates the skin nor harm health) 15) Prevent mould from growing 16) Acid-resisting and alkali-resisting 17) service life: above 25 years   3.Applications: BOLNFLEX insulation sheet roll is widely used in heat preservation and insulation of HVAC system, and its chilled water pipes, condensate pipes, air ducts and hot-water pipes of air-condition equipments, and other industrial system. It’s the preferred material for low temperature. And it also can be used for mining system. pipelines because of the best moisture-proof property. Furthermore,it's also widely used in high lustration environments of tobacco ,medicine,electronic,car,foodstuff industry etc.   4.Data
