NBR/PVC rubber foam tubes for insulating Characteristics of our rubber tubes:1. Closed-cell Structure.2. Low Heating Conductivity.3. Low Water Absorption Rate.4. Good Fireproof and Soundproof Performance.5. Good Aging Resistance Performance.6. Simple and Easy Installation. Application of rubber tubes:Rubber tubes are used to retard heat transmission and control condensation from chilled-water and refrigeration systems. It also efficiently reduces heat transfer for hot-water plumbing and liquid-heating and dual-temperature piping Rubber tube is ideal for applications in:DuctworkDual temperature and low pressure steam linesProcess pipingAir-conditioner, including hot gas piping Technical specifications:PropertyUnitValueDensity rangekg/m³50~150Flammability     -B1Oxygen index%≥33Thermal conductivity --Average tempreture
