3R 871
COMPRESSED SHEET
NBR ARAMID FIBER

ISO 9001 : 2000 Certified
The 3R 871 is a non-asbestos compressed sheet gasket materiel produced from a combination of aramid fiber, inorganic filler and bonded with Nitrile rubber. (NBR). The 3R 871 is an ideal material for the sealing gaskets used in presence of air, oils, steam and neutral solutions.

Applications //

3R 871 has numerous applications in the process industries handling media like:


- Mild acids and alkalis	- General chemicals	- Industrial gases
- Hydrocarbons	- Water	- Neutral solutions
- Gasoline	- Oils
- Air	- Steam
