1. Splendid Surface
Nitron-Bubble NBR/PVC insulation material has a flat and even surface without obvious goffer. Under pressure, it appears symmetrical skin-like wrinkle, which takes on noble and top grade quality.
2. Excellent OI Critical Value
Nitron-Bubble NBR/PVC insulation material requires a high oxygen index, which makes it possess great fireproof capability.
3. Outstanding Smoke Density Class
Nitron-Bubble NBR/PVC insulation material has quite a low smoke density class as well as low smog thickness, which provide good action when it is burning.
4. Agelong Life In Heat Conductivity Value (K-Value)
Nitron-Bubble NBR/PVC insulation material has a long-term, stable K-value, which guarantees a long life span of the products.
5. High Moisture Resistance Factor (u-Value)
Nitron-Bubble NBR/PVC insulation material has a high moisture resistance factor, u≥15000, which gives it a strong ability in anti-condensation.
6. Firm Performance in Temperature and Anti-Aging
Nitron-Bubble NBR/PVC insulation material has excellent capability in anti-ozone, anti-insolation, and anti-ultraviolet, which ensures a long life span.
