| For example, the extent of the Antarctic ozone hole and its relation to fluorocarbon use were confirmed by this means. |
| These pumps may be either rotary or positive, may have displacement and fluorocarbon seals, and may have special working fluids present. |
| The final goal is to substitute a fluorocarbon liquid for water, relying on the silicon cylinders to standardize the density of the fluorocarbon. |
| The most widely used fluorocarbon polymer is polytetrafluoroethylene, a high-melting nonstick plastic commonly known by the trademark Teflon. |
| They create compounds of waxes, fluorocarbon powders, graphite, and other closely guarded ingredients and meticulously test each concoction in varying racing conditions. |
| On slack tide just off the mouth of Florida's Indian River, for example, even live threadfins on 6 feet of fluorocarbon leader sometimes cannot get a snook's attention. |
