Neoprene/Nitrile Rubber Bonded Cork (ref 2015)
Excellent general-purpose gasketing material, it's toughness and good compressibility characteristics make it highly satisfactory in a very wide range of applications. The material has a very low swelling in oils and fuels, which makes it especially suitable for transformer applications
Key Features
- Good Compressibility
- Low swelling in oils and fuels
- Suitable for transformer applications
