Self extinguishing and no drips according to ASTM D635-91.
Rubber foam is your smart choice for energy saving, with low thermal conductivity ≤0.034 W/m.K.
No dust and fiber, CFC free, Low VOCs, No fungal growth, Negligible bacterial growth.
Due to rubber foam high flexible performance, it is easy to bend and irregular pipes, cut into different shapes and sizes and can save labor and materials.
Can custom various colors such as red, blue, green, grey, yellow, grey and so on. Your finished piping lines will be much nicer and it is easy to distinguish different pipes inside for maintaining.

The rubber foam offers low thermal conductivity, measuring ≤0.034 W/m.K, making it highly effective for energy-saving insulation projects.
It features excellent fire performance. It is self-extinguishing and produces no drips under the ASTM D635-91 standard tests, while also meeting Class 0 & Class 1 standards (BS 476 Part 6 & 7).
Yes. The material is dust-free, fiber-free, CFC-free, has low VOC emissions, and exhibits no fungal or bacterial growth, ensuring safety for indoor environments.
Yes, we can customize a variety of colors, such as red, blue, green, grey, and yellow. Custom colors make finished piping systems look better and simplify the identification of different lines during maintenance.
Absolutely. Due to its high flexibility, the rubber foam is easy to bend, wrap around irregular pipes, and cut into custom shapes and sizes. This helps save both labor costs and materials during installation.
The material operates effectively within a temperature range of -50°C to 110°C, tested in compliance with GB/T 17794-1999 standards.
