The insulation pipes are manufactured from a high-quality blend of nitrile rubber and polyvinyl chloride. They are completely free of fiber dust, benzaldehyde, and chlorofluorocarbons, ensuring safe and clean performance.
The product has low electrical and thermal conductivity (≤0.030 W/(m.k) at -20°C), outstanding moisture resistance, and operates efficiently within a temperature range of -50°C to 110°C.
The rubber foam features excellent fire-resistant properties, achieving Class 0 & Class 1 fire ratings according to BS 476 Part 6 & 7 standards, alongside a 25/50 Flame Spread and Smoke Developed Index under ASTM E 84.
Yes, it offers verified durability with excellent resistance to ozone (GB/T 7762-1987), fungi (ASTM 21), and U.V. / weathering (ASTM G23).
It is available in tube, roll, and sheet forms. The extruded flexible tubes are specifically formatted to fit standard diameters of copper, steel, and PVC pipes, while sheets are supplied in standard precut sizes or rolls.
Installation is very simple. They can be placed on new lines or retrofitted onto existing pipes. You only need to cut the material to size and glue it together, without affecting the material's insulating performance.
