Product Performance & Features

Perfect Heat Preservation Insulation

The high density and closed structure of selected raw material has the ability of low thermal conductivity and stable temperature and has an isolation effect of hot and cold medium.

Good Flame Retardant Properties

When burned by fire, the insulation material do not melt and resulting in low smoke and do not make the flame spread which can guarantee the using safety; the material is determined as nonflammable material and the range of Using temperature is from -50℃ to 110℃.

Eco-Friendly Material

The environmental friendly raw material has no stimulation and pollution, no hazard to health and environment. Moreover, it can avoid the mold growth and mouse biting; The material has the effection of corrosion-resistant, acid and alkali, it can increase the life of using.

Easy to Install, Easy to Use

It is convenient to install due to it is not need to install other auxiliary layer and it is just cutting and conglutinating. It will save the manual work greatly.

Frequently Asked Questions

What materials are used to manufacture these insulation tubes?

Our insulation tubes are manufactured primarily from high-performance NBR (Nitrile Butadiene Rubber) and PVC (Polyvinyl Chloride) blends. These materials are processed using a specialized foaming craft to ensure a soft structure with excellent insulation performance.

What is the safe operating temperature range for this insulation?

The insulation is designed to perform safely and reliably across a wide temperature range, specifically from -50°C up to 110°C, making it suitable for both cold and hot medium isolation.

Does this insulation product meet flame retardant safety standards?

Yes, the material features excellent flame retardant properties. When exposed to fire, it does not melt, generates low smoke, and prevents flame spread. It is classified as Class 0 and Class 1 under the BS 476 Part 6 & 7 standard and is determined to be nonflammable.

Is the material environmentally friendly and safe for indoor use?

Absolutely. The raw material is eco-friendly, non-polluting, and poses no hazard to health or the environment. It is formulated to resist mold growth, prevent rodent damage, and offer excellent resistance against acids, alkalis, and ozone.

How is the insulation tube installed?

Installation is simple and highly efficient. The material does not require any additional auxiliary layers. It can be easily cut to fit and conglutinated using proper adhesives, saving significant labor time and costs.

How does the insulation prevent energy loss and condensation?

Thanks to its closed-cell structure and high density, the material has a very low thermal conductivity rating (≤0.032 W/(m.k) at 0°C) and excellent water vapor permeability resistance. This setup successfully isolates hot or cold media, preventing condensation and energy loss.
