Frequently Asked Questions

1. What formats and options are available for this Class 0/1 insulation?

The insulation is available in tube, roll, and sheet forms. The standard color is black, but other custom colors can be requested to match specific requirements.

2. Can the flexible tubes fit standard pipe dimensions?

Yes. The extruded flexible insulation tubes are engineered to fit standard outer diameters of copper, steel, and PVC piping structures seamlessly.

3. What is the working temperature range of the insulation material?

The material exhibits safe and stable performance under a broad temperature scope ranging from -50°C to 110°C, tested in compliance with GB/T 17794-1999 standards.

4. How does the closed-pore structure improve moisture resistance?

The closed-cell foaming configuration yields a very low water vapor permeability (≤ 0.91 × 10⁻¹³ Kg/(m·s·Pa)), preventing moisture absorption and protecting pipes from condensation.

5. What fire safety ratings does this insulation hold?

It holds Class 0 and Class 1 fire ratings according to BS 476 Part 6 & Part 7 testing, and has a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84.

6. Does the insulation withstand environmental and biological degradation?

Yes. It features good resistance to ozone (GB/T 7762-1987), fungi growth (ASTM 21), and UV weathering (ASTM G23), ensuring durability for long-term deployments.
