Rubber Foam Pipe Used In HVAC Refrigeration Hot And Cold Water Building Industry Pipelines And Some Other Equipments

NBR rubber foam tube is a black, flexible elastomeric foam tube used to conserve energy and prevent condensation on piping applications. The tube closed cell properties create exceptional thermal and acoustic insulation, protect against moisture penetration and provide the best solution for applications within a -40℃~105℃ temperature range. It is primarily used in the HVAC/R market.ItemUnitPerformance Index0ⅠⅡBoardPipeBoardPipeBoardPipeApparent DensityKg/m365-7050-6550-65Combustion Performance--Grade0GradeB1GradeB2Oxygen Index≥40Oxygen Index≥32Oxygen Index≥28Smoke Density≤70Smoke Density (SDR)≤75Smoke Density (SDR)≤75Heat Conductivity(Average temperature)W/m·k≤0.034Water Vapor PermeabilityCoefficientG/m, s, p, a≤4.4×10－10Factors--≥4.5×103Water Absorption Ratio in VacuumKg/m2≤0.08Dimension Stability%≤2.0Tear StrengthN/cm≥3.0Compression Resilience Ratio      (Compression Ratio 50% Compression Time 72h)%≤70Aging Resistance (150h)--Slight corrugation, no flaw, no pin hole, no deformationService temperature℃-40~150Application Closed pore rubber foam tubes are used for the heat-insulating and heat-preservation of shell of big tanks and piping in the construction, business and industry ,cold and hot water pipe, heat insulation of air ducts of central air conditioners,heat insulation of joint pipes of household air conditioners and automobile air conditioners.
