Rubber foam pipe can be used to insulate pipes and equipment. Due to the low thermal conductivity of the rubber-plastic insulation board, it is not easy to conduct energy, so it can be used for both heat insulation and cold insulation.
Rubber foam pipe can be used to protect pipes and equipment. The material of the rubber-plastic insulation pipe is soft and elastic, which can cushion and absorb shock. The rubber-plastic insulation pipe can also be waterproof, moisture-proof and corrosion-proof.
Rubber foam pipe can play a decorative role on pipes and equipment. The appearance of the rubber-plastic insulation pipe is smooth and flat, and the overall appearance is beautiful.
Rubber foam pipe has very good stability and can play a good role in preventing fire.
Rubber foam pipe is flexible, so it is easy to install when it needs to be bent.

Frequently Asked Questions (FAQ)
What are the primary uses of rubber foam pipes?
Rubber foam pipes are primarily used to insulate, protect, and decorate pipes and equipment. They are suitable for both heat and cold insulation due to their low thermal conductivity.
What is the operating temperature range for this insulation material?
The safe temperature range for the rubber foam pipe is from -50°C to 110°C, conforming to the GB/T 17794-1999 test standard.
How does the rubber foam pipe perform in fire safety tests?
The material offers excellent fire performance, achieving Class 0 & Class 1 fire ratings under the BS 476 Part 6 & 7 standards, and has a high oxygen index of ≥36.
Is the material resistant to environmental factors like UV and moisture?
Yes, it features good resistance to fungi, ozone, UV, and general weathering. Additionally, it has a low water vapor permeability (≤0.91×10 ﹣¹³ kg/(m.s.pa)), which provides strong protection against moisture.
Is this rubber foam pipe easy to install around corners?
Absolutely. The rubber foam pipe is highly flexible and elastic, allowing it to bend easily during installation and absorb physical shocks effectively.
What is the thermal conductivity value of this insulation?
According to ASTM C 518, the thermal conductivity is ≤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 energy conservation.
