Low thermal conductivity

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

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.

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 (FAQ)

Q1: What are the main raw materials of this rubber foam insulation?

A1: It is manufactured using Polyvinyl Chloride (NBR, PVC) as the main raw materials, combined with high-quality auxiliary materials, processed through a special continuous foaming process.

Q2: Why is the closed-cell foam structure beneficial?

A2: The closed-cell structure contains independent bubble holes that are not connected. This forms a complete vapor barrier layer, providing reliable resistance against water vapor transmission and maintaining insulation efficiency even if the surface is damaged.

Q3: What is the operating temperature range for this material?

A3: The rubber foam insulation performs optimally within a temperature range of -50°C to 110°C, making it suitable for both cold and hot piping systems.

Q4: Does the material have fire-resistant properties?

A4: Yes, it achieves a Class 0 & Class 1 fire rating according to BS 476 Part 6 & 7 testing standards, and has a flame spread/smoke developed index of 25/50 under ASTM E 84.

Q5: Can it be installed on irregular pipes and bends?

A5: Absolutely. Its excellent flexibility makes it highly adaptable to various bends, joints, and irregular piping surfaces, which simplifies construction, saves labor, and reduces material waste.

Q6: How does the thermal conductivity change with temperature?

A6: Based on standard testing (ASTM C 518), the thermal conductivity is extremely low: ≤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, ensuring excellent thermal efficiency.
