1. Low thermal conductivity

Cellular foam structure, low thermal conductivity, high surface heat release coefficient, good thermal insulation effect.

2. Closed-cell foam structure

Closed pore structure, independent bubble holes are not connected, forming a closed vapor barrier layer, which can form multiple barriers to water vapor molecules. Even if the pipe surface is damaged, it can still achieve vapor isolation.

3. Good flexibility

Rubber foam rolls are flexible, suitable for all kinds of bends and irregular pipes, convenient for construction, saving work and materials.

Frequently Asked Questions

What are the primary raw materials used in Kingflex insulation?

Kingflex insulation material is primarily manufactured from polyvinyl Chloride (NBR, PVC) as the main raw materials, processed along with other high-quality auxiliary materials using advanced foaming technology.

How does the closed-cell foam structure improve insulation performance?

The closed-cell structure consists of independent, unconnected bubble holes. This creates a highly effective, built-in vapor barrier that prevents water vapor from penetrating, ensuring long-term thermal isolation even if the outer surface is damaged.

Is Kingflex insulation suitable for bending or irregular piping?

Yes. Because of its outstanding flexibility, these rubber foam rolls can easily conform to all types of bends and complex pipe geometries. This makes installation faster and reduces labor and material wastage.

What is the operational temperature range of this rubber foam?

According to the technical data, Kingflex rubber foam performs reliably across a temperature range of -50°C to 110°C, verified by test method GB/T 17794-1999.

What are the fire performance and safety ratings of this material?

It achieves a Class 0 & Class 1 fire rating according to BS 476 Part 6 & 7. Additionally, it has a Flame Spread and Smoke Developed Index of 25/50 (ASTM E 84) and an Oxygen Index of ≥36 (GB/T 2406, ISO4589).

How stable is the material under environmental exposure like UV and ozone?

The technical data shows that Kingflex has good resistance to fungi (ASTM 21), ozone (GB/T 7762-1987), and UV/weathering (ASTM G23), ensuring a long and durable operational lifespan.
