Why NBR Gaskets Are Ideal for Transformer Sealing
Introduction Sealing in oil-filled transformers is critical to prevent oil leaks, moisture ingress, and insulation damage. Choosing the right gasket ensures safety, performance, and long service life. What Is NBR (Nitrile Rubber) NBR (nitrile-butadiene rubber) is a synthetic elastomer known for its oil, grease, and fuel resistance, good mechanical strength, and flexibility. Its acrylonitrile content affects oil resistance and low-temperature performance. Key Advantages Oil & Fuel Resistance: Prevents swelling and leaks. Mechanical Strength: Tensile, tear, and abrasion resistant. Temperature Range: Performs well from -40°C to +100°C (air) and up to ~120°C in oil. Cost-Effective: High performance at lower cost. Compression & Seal Integrity: Maintains a tight seal under load. Limitations Not suitable for prolonged high temperatures (>120°C). Can become brittle below -40°C. Sensitive to strong chemicals, ozone, and UV exposure. Tips for Select...
