Rubber foam insulation tube is a uniquely formed closed cell flexible elastomeric insulation, used to insulate heating, ventilating, air-conditioning, refrigerating (HVAC/R). The insulation tube is also CFC/HCFC free, non-porous, fiber free, dust free and resistant to mold growth. The recommended temperature range for insulation is -50℃ to +110℃.
