What are the primary performance advantages of this elastomeric insulation?
This material offers excellent low-temperature flexibility, low thermal conductivity, and a high water vapor resistance factor (>5500). It is also dust-free and designed for fast, clean, and easy installation.
What is the fire rating and safety classification of the insulation material?
The material achieves Class 0 & Class 1 fire ratings under BS 476 Part 6 & 7. Additionally, it has a Flame Spread and Smoke Developed Index of 25/50 according to ASTM E 84, and an Oxygen Index of ≥36.
How does the thermal conductivity vary with different temperature levels?
According to ASTM C 518 test standards, 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.
What sizing options (width and thickness) are available for these rolls?
Thicknesses range from 1/4" (6mm) to 2" (50mm). Roll widths are available in 1m, 1.2m, and 1.5m to accommodate various industrial and commercial installation requirements.
How well does this insulation resist environmental hazards and weathering?
It demonstrates good performance and resistance against fungi growth (ASTM 21), ozone degradation (GB/T 7762-1987), and U.V./weather exposure (ASTM G23), ensuring long-term durability.
