Nitron-Bubble NBR/PVC insulation material has flat and even surface without obvious goffer. Under pressure, it appears symmetrical skin-like wrinkle, which takes on noble and top grade quality.
Nitron-Bubble NBR/PVC insulation material requires high oxygen index, which makes it great fireproof capability.
Nitron-Bubble NBR/PVC insulation material has quite low smoke density class as well as low smog thickness, which provide good action when it is burning.
Nitron-Bubble NBR/PVC insulation material has long-term, stable K-value, which guarantee long life span of the products.
Nitron-Bubble NBR/PVC insulation material has high moisture resistance factor, u≥15000, which makes it a strong ability in anti-condensation.
Nitron-Bubble NBR/PVC insulation material has excellent capability in anti-ozone, anti-insolation and anti-ultraviolet, which ensures long life span.

Rubber foam products are produced by imported high-end technology and automatic continuous equipment. We have developed a rubber foam insulation material with excellent performance through in-depth research. The major materials we use are NBR/PVC.
The main materials used are high-quality NBR (Nitrile Butadiene Rubber) and PVC (Polyvinyl Chloride), processed using imported high-end technology and automatic continuous equipment.
It achieves a Class 0 & Class 1 fire rating tested under 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.
The NBR/PVC insulation material features a high moisture resistance factor (μ-value ≥ 10000, and up to μ≥15000 in certain configurations), giving it excellent capabilities to resist water vapor transmission and prevent condensation.
It operates effectively within a temperature range of -50°C to 110°C, making it suitable for a wide variety of industrial and commercial thermal insulation applications.
Yes, it demonstrates outstanding durability with excellent resistance to ozone, UV radiation, fungi, and general outdoor weathering conditions according to ASTM and GB standard testing.
