PROPERTIES OF VITON RUBBER SHEET
The chemical and physical properties of Viton rubber sheets that make it extremely popular for usage are:
- The Viton Rubber Sheets exhibit excellent resistance towards high temperature and low compression set which allows it to be a preferred choice for the lining of hoses in automobile industry. Also, the Viton sheets are resistant towards prolonged exposure to petroleum oils even in high temperatures.
- The Viton sheets have the best resistance to chemicals and most organic solvents as compared to all the other synthetic rubber sheets.
- The FKM sheets have excellent resistance over the operating temperature ranging from -20 F to +400 F towards:
- Oxygen
- Synthetic hydraulic fluids
- Mineral oil
- Ozone
- Aromatics
- High temperatures
- Chemicals
- The gas permeability of the PKM sheets is extremely low and similar to Butyl Rubber sheets. However, it exhibits a poor performance when exposed to bases, ethers and ketones.
USES OF VITON RUBBER SHEETS
The major usage of Viton is for the manufacture of goods made by molding or extruding. Some of them are:
- O-rings
- Gaskets
- Seals
Sports equipment manufacture:
- Scuba diving equipments
Automobile and transportation industry:
- Lining of hoses transporting fuel
