Refrigerant Pipe Insulation
Isoline (from K-Flex) is a high-quality Class-1 Elastomeric/Rubber Insulation which is a flexible, closed-cell tube insulation product used to conserve energy and prevent condensation on piping applications. The product’s closed-cell structure creates exceptional thermal properties that protect against moisture penetration in refrigeration tubing applications.
Very low thermal conductivity high water vapor diffusion resistance: Closed-cell elastomeric insulation has a high water vapor diffusion resistance factor µ (µ>̲5000) which minimizes water vapor penetration, giving an excellent long-term performance.
Low flame spread: When fire tested, ISOLINE does not generate flaming droplets and has low flame spread achieving the fire performance of Class 1
Fire: Class 1 BS 476 Pt 7 1997
Ozone Depletion: Zero
HCFC-CFC free
Standard length : 6 FEET LONG CLASS “1” PIPE SECTIONS
