Flexible rubber foam insulation material is a kind of environmental protection insulation material with closed cell structure. It is manufactured without the use of CFCS, HFCS or hydrofluorocarbons. It is also formaldehyde-free, low in volatile organic compounds, dust-free, and resistant to mold and mildew. It is widely used in HVAC engineering, refrigeration equipment, hot and cold water pipes to ensure the tightness of the entire system.

Frequently Asked Questions
What temperature range can this rubber foam insulation material withstand?
This flexible rubber foam insulation operates efficiently within a temperature range of -50°C to 110°C, making it suitable for hot and cold pipes as well as HVAC systems.
What is the fire performance rating of this insulation material?
The insulation material achieves a Class 0 & Class 1 fire rating according to the BS 476 Part 6 and Part 7 test standards, along with a flame spread and smoke developed index of 25/50 per ASTM E 84.
Is this insulation material environmentally friendly?
Yes. It is manufactured without the use of CFCS, HFCS, or hydrofluorocarbons. It is also formaldehyde-free, releases low volatile organic compounds, remains dust-free, and prevents the growth of mold and mildew.
What is the thermal conductivity of the flexible rubber foam?
The thermal conductivity values are extremely low, measuring ≤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, providing excellent heat retention and energy efficiency.
What dimensions and thicknesses are available for installation?
It is available in standard thicknesses ranging from 1/4" (6mm) to 2" (50mm). Roll widths come in 1m, 1.2m, and 1.5m to fit various installation requirements.
Does this insulation offer moisture and environmental resistance?
Yes, with a high water vapor permeability resistance (μ ≥ 10000) and good ratings for ozone, UV, weather, and fungi resistance, it is highly durable in challenging environments.
