Frequently Asked Questions

What are the primary applications of this closed cell rubber foam insulation?

This insulation material is widely used for piping systems in air conditioning, construction, chemical processing, medicine, and light industries due to its excellent thermal and protective characteristics.

How does this insulation perform in fire-rated environments?

It features outstanding fire-resistance performance with a Class 0 & Class 1 fire rating according to BS 476 Part 6 & 7. Additionally, it has a high oxygen index (≥36) and generates low smoke density, ensuring enhanced building safety.

What is the thermal conductivity (K-Value) of the material?

The material provides low thermal conductivity to ensure high thermal efficiency. Its 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, helping keep buildings energy-efficient throughout the seasons.

Does this insulation absorb moisture easily?

No, it has exceptional water vapor resistance with a permeability of ≤0.91×10 ﹣¹³ Kg/(m.s.pa) and a high diffusion resistance factor (μ ≥ 10000), which effectively prevents moisture penetration and preserves its insulation qualities.

What operating temperature range can the material withstand?

The rubber foam insulation performs optimally within a wide temperature range of -50°C to 110°C, making it highly versatile for both extreme cold and hot pipeline configurations.

Is the insulation material environmentally friendly and easy to install?

Yes. It is environmentally friendly and offers good pliability and anti-vibration properties. Its flexible nature ensures a smooth, easy installation process and yields a neat, clean appearance upon completion.
