PTFE Seals Anti-aging

Polytetrafluoroethylene gasket Because of the unique performance of "polytetrafluoroethylene", it makes it "mechanical", "electronic", "oil", "chemical", "food", "paper", "textile" , "Aerospace", "ocean" and other fields have a very wide range of applications.

First, the "anti-corrosion" performance applications

We all know that "metal alloy", "glass", "rubber" and so on in the industry also has a wide range of applications, but they are "corrosion-resistant" aspects of the harsh conditions of "pressure", "temperature", "chemical "Coexistence of the environment. The resulting loss is surprisingly high, but the excellent corrosion resistance of polytetrafluoroethylene products is therefore used as the main corrosion-resistant material in "textile", "chemical", "oil" and other industries.

Polytetrafluoroethylene products in the "textile", "chemical", "oil" and other industries to do the main corrosion-resistant materials include: transport corrosive gases "pipe", "steam pipe", "exhaust pipe", " High pressure tubing "," cold press "," distillation column ", tower, tank, kettle" lining "," valve "and other chemical equipment.

Teflon gasket "Corrosion resistance", "anti-aging", "low friction coefficient", "no adhesion", "wide temperature range" and "good elasticity" Widely used in high corrosion resistance requirements, the temperature is higher than 100 degrees Celsius use of the environment to do the seal. It is well known that the performance of the seal will have a great impact on the performance and efficiency of the whole machinery and equipment, such as "machine", "heat exchanger", "large diameter container", "high pressure vessel" "Valve", "valve", "the valve rod", "the piston rod", "the valve", "the valve", " "Rod", "worm gear", "shaft" and the like.

Second, the "low friction performance" in the application of the load

Not all of the equipment friction parts can be lubricated, like lubricating grease will be dissolved in the solvent and the failure of the occasion or "textile", "paper" | "food", "pharmaceutical" and other industrial products need to "avoid lubrication Oil stains ", which makes the" filling PTFE material "as mechanical equipment parts without oil lubrication (direct load) the best material. This is because the friction coefficient of the material is the lowest of known solid materials. The specific uses include "papermaking machinery", "chemical equipment", "agricultural machinery bearings", used as "machine tool guide", "piston ring", "guide ring"; in civil engineering works widely used as "large chemical Pipe "," tunnel "," tank support slider "," bridge "," steel roof truss ", and as" bridge bearing "and" bridge swivel "and so on.
