The primary materials are high-performance butyronitrile rubber and polyvinyl chloride (NBR, PVC), combined with auxiliary materials and manufactured via a specialized foaming process.
This material operates efficiently within a temperature range of -50°C to 110°C, tested in compliance with standard GB/T 17794-1999.
Yes, it is highly fire-resistant with a Class 0 and Class 1 fire rating according to BS 476 Part 6 & Part 7, and has a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84.
The closed-cell structure provides high moisture resistance, prevents water vapor permeability (≤0.91×10 ﹣¹³ Kg/(m.s.pa)), and ensures excellent long-term thermal insulation performance.
This insulation tube is certified to multiple standards, including BS476, UL94, DIN5510, ASTM, CE, REACH, ROHS, and GB standards.
It exhibits good resistance to fungi (tested by ASTM G21), excellent ozone resistance (GB/T 7762-1987), and outstanding resistance to weathering and U.V. exposure (ASTM G23).
