Closed cell flexible rubber foam pipe insulation is made from NBR and PVC as main raw material and other high quality auxiliary materials through foaming, It can be widely used for air condition, construction, chemical industry, medicine, light industry and so on.
Frequently Asked Questions (FAQ)
What are the primary benefits of closed cell flexible rubber foam insulation?
It features excellent fire-resistance performance, low thermal conductivity, high moisture resistance, superior pliability, and outstanding sound absorption properties, which collectively improve building energy efficiency.
In what temperature range can this rubber foam pipe insulation be used?
This insulation operates effectively within a broad temperature range of -50°C to 110°C, making it suitable for hot and cold water pipes, air conditioning systems, and industrial pipelines.
How does the material prevent moisture ingress and condensation?
Due to its closed-cell structure and low water vapor permeability (μ ≥ 10000), it functions as a built-in vapor barrier, effectively preventing moisture entry and reducing the risks of corrosion under insulation (CUI).
Does this insulation material meet industry safety standards for fire?
Yes, it achieves a Class 0 & Class 1 fire rating according to BS 476 Part 6 and Part 7 standards. It also maintains a low smoke density and flame spread index in line with ASTM E 84.
Is the material environmentally friendly and resistant to biological growth?
Yes, it is environmentally friendly, free from CFCs and other harmful chemicals, and offers good fungi resistance as tested by ASTM G21, preventing mold growth inside buildings.
