Key Characteristics
Good ozone resistance and extendibility.
Further Comments
Very good water resistant, and this resistance is maintained to high temperatures (up to 180°C in steam, for peroxide cures). The highest temperature resistance is achieved by using peroxide cured grades. Has excellent resistance to atmospheric ageing, oxygen and ozone up to about 150°C. It has good resistance to most water-based chemicals and to vegetable-based hydraulic oils. It has poor resistance, however, to mineral oils and diester based lubricants.
