What is the recommended operating temperature range for these insulation sheets?
These insulation sheets have an operational temperature range of -50°C to 110°C (-58°F to 230°F), conforming to GB/T 17794-1999 test standards, making them suitable for both hot and cold piping systems.
What are the fire safety ratings of this thermal insulation?
The insulation material complies with Class 0 and Class 1 fire standards according to BS 476 Part 6 & 7. It also has a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84, ensuring excellent fire safety performance.
How does the material prevent moisture build-up and water absorption?
The material features a closed-cell structure with a water vapor permeability rating of ≤0.91×10⁻¹³ Kg/(m.s.pa) and a water vapor resistance coefficient (μ) of ≥10000. This provides a built-in vapor barrier to effectively minimize moisture ingress.
What is the thermal conductivity of this insulation at different temperatures?
Tested under ASTM C 518, the thermal conductivity values are ≤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, delivering optimal thermal resistance performance.
Does the insulation support environmental resistance?
Yes, the insulation displays good resistance to ozone (GB/T 7762-1987), UV and weathering (ASTM G23), as well as excellent fungi resistance (ASTM G21), ensuring reliable long-term durability in outdoor and harsh environments.
What widths and thicknesses are available for the insulation rolls?
The insulation sheets come in roll widths of 1m, 1.2m, and 1.5m. Thickness options range from 1/4" (6mm) up to 2" (50mm) to accommodate varying thermal and architectural requirements.
