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.

The rubber foam insulation material is developed through in-depth research using NBR/PVC as the primary raw materials.
This material achieves a Class 0 & Class 1 fire rating according to BS 476 Part 6 & Part 7 testing, with an Oxygen Index of ≥36. It is designed to provide excellent fireproofing and has quite low smoke density class and thickness during burning.
With a high moisture resistance factor (u-Value) of ≥15000 (and μ ≥ 10000 in specific tests), it provides excellent anti-condensation capability, preventing moisture from penetrating the insulation.
The thermal conductivity is stable and long-term: ≤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 high energy efficiency and a long life span.
Yes. The insulation material offers excellent capability in anti-ozone, anti-insolation, and anti-ultraviolet weathering. It registers "Good" results under ASTM G23 for U.V. and weather resistance, and GB/T 7762-1987 for ozone resistance.
This rubber foam insulation is designed to operate safely and effectively within a temperature range of -50°C to 110°C, according to the GB/T 17794-1999 test standard.
