1.Splendid Surface Nitron-Bubble NBR/PVC insulation material has flat and even surface without abvious 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 high oxygen index, which makes it great fireproof capability. 3. Outstanding Smoke Density Class 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. 4. Agelong Life In Heat Conductivity Value (K-Value) Nitron-Bubble NBR/PVC insulation material has long-term, stable K-value, which guarantee long life span of the products. 5. High Moisture Resistance Factor (u-Value) Nitron-Bubble NBR/PVC insulation material has high moisture resistance factor, u≥15000, which makes 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 long life span.
