Frequently Asked Questions

What are the primary materials used in rubber foam insulation tubes?

The primary materials used in these insulation tubes are high-quality NBR (Nitrile Butadiene Rubber) and PVC (Polyvinyl Chloride), manufactured through advanced, automatic continuous extrusion technology.

What is the fire resistance rating of this insulation material?

The material achieves Class 0 & Class 1 fire ratings according to BS 476 Part 6 and 7 testing standards, featuring a high oxygen index (≥36) and extremely low smoke density.

Can this insulation tube be used in extreme temperatures?

Yes. The temperature range of this rubber foam insulation material spans from -50°C up to 110°C, making it highly stable and suitable for both cold and hot piping systems.

Why does the insulation perform well in humid environments?

It features excellent moisture resistance with a high water vapor permeability resistance factor (μ ≥ 10000), preventing condensation build-up and securing long-term thermal efficiency.

Is this product safe for the environment and easy to install?

Absolutely. The material is environmentally friendly, clean, dust-free, and offers good pliability and vibration resistance, allowing quick and neat installation.
