KingwellRubber foam insulation tube/pipe has low thermal conductivity, full-closed structure, and excellent continuous heat insulation. The material is completely isolated with vapor, so it has the properties of water-proof, anti-condensation and long lifetime. After SGS testing, its measured value is much lower than EU standard value on materials without toxic substances, so it is safe and healthy. With beautiful appearance, it is easy for bending and construction, and no need of other accessories. With fine resistance to temperature and climate, it is much applicable for heat preservation of hot-water pipe of solar energy water heater, air conditioning pipe of motorcar and steam pipe. Also in areas of shock reduction and sound absorption.Characteristics: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.7. CFC/HCFC free.Application:KingwellRubber foam insulation tube/pipe is 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 pipingItis ideal for applications in:DuctworkDual temperature and low pressure steam linesProcess pipingAir-conditioner, including hot gas pipingPRODUCT DATAPropertyUnitValueTest MethodTemperature range°F (°C)-297 220 (-183 105)-Density rangelbs./ft³(kg/m³)3.0 6.0 (48 96)ASTM D1622 or D1667Thermal conductivity75°F mean T (24°C)Btu·in./h·ft²·°F (W/mK)0.27 (0.039)ASTM C177 or C518 90°F mean T (32°C)Btu·in./h·ft²·°F (W/mK)0.276 (0.040)Water vapor permeabilityperm-in (kg/m·s·pa)0.08 (1.16×10-13)ASTM E96 Procedure A DIN 52615Flame spread and smoke developed index-25/50ASTM E84, CAN/ULC S 102V0UL94Water absorption, by volume%0.2ASTM C209Mold growth-meet requirementUL181Bacterial resistancemeet requirementASTM G22Fungi resistancemeet requirementASTM G21/C1338Resistance to agent chemical-stable performance to agent chemical-Ozone resistance-goodASTM D1149Aging resistance-150 hours, slight wrinkles, no cracks, holes or distortion-Wall thickness (normal)in (mm)1/4", 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2", 2" (6, 9, 13, 19, 25, 32, 40, 50)-Inside diameter, tubular formin (mm)1/4" ID to 6" IPS (6 ID to 168)-Length of section, tubular formft (m)6.82 (2)-Packaging:In CartonThe length of 1.0 to 2.0M is available to provide.Kingwell Industries Asia Pacific Company Limitedis a global enterprise with core competencies in the field of rubber insulation, which are widely used in the HVAC/R industry, including commercial/ industrial air-conditioning system, plumbing system, and ducting system.
