Bellsafe flex pipe (tube) insulation is a flexible elastomeric thermal insulation that is black in color.The expanded closed-cell structure of Bellsafe flex pipe insulation makes it an efficient insulation. Bellsafe flex pipe insulation is used to retard heat gain and control condensation drip from cold-water plumbing, chilled-water, and refrigeration lines. It also efficiently reduces heat flow for hot-water plumbing and liquid-heating and dual-temperature piping Some of the benefits of using Bellsafe flex closed cell pipe covering include Superior condensation control Retarding heat gain Technical Performance Density 50 kg/M3 + 10%Temperature Range-40 to + 110 Thermal Conductivity W/m.K 0.036W/M.K@0 0.037W/M.K@20 Water AbsorptionAfter 28 days-max 0.9% Corrosion RiskpH7 (neutral) Ecological DataNo asbestos No HCFC-CFC No formaldehyde-Cd-Hg etc.Closed Cell>90% Ozone ResistanceGood Resistance to Oil & GreaseGood OdourNegligible Noise Reductionupto 35dB (A) Noise Absorption to EN ISO 11654Class DReaction to Fire BS 476 Part 7 Class1Resistance to Building MaterialVery Good DimensionsSheet in rolls 1 mtr or 1.2 mtr width.
