This insulation sheet offers excellent low water absorption, good fireproof and soundproof characteristics, anti-aging properties, high flexibility, and strong vibration resistance. The integrated aluminum foil layer provides enhanced anti-UV, anti-oxidation, and corrosion-resistant performance.
The thermal conductivity varies by temperature: it is ≤0.030 W/(m.k) at -20°C, ≤0.032 W/(m.k) at 0°C, and ≤0.036 W/(m.k) at 40°C, tested in compliance with ASTM C 518 standards.
It meets Class 0 & Class 1 fire standards according to BS 476 Part 6 and 7 testing. Additionally, it has a Flame Spread and Smoke Developed Index of 25/50 per ASTM E 84, and an Oxygen Index of ≥36 (GB/T 2406, ISO4589).
Yes, it has a closed-pore foaming structure which yields a low water absorption rate (20% by volume under ASTM C 209) and a high water vapor permeability resistance factor (μ ≥ 10000), ensuring excellent damp-proof stability.
It operates reliably within a temperature range of -50°C to 110°C, conforming to the GB/T 17794-1999 test guidelines, making it suitable for hot and cold pipe insulation alike.
Standard thicknesses range from 1/4" (6mm) to 2" (50mm). Available width options include 1.0m, 1.2m, and 1.5m, with varying roll lengths depending on the selected thickness.
