Plastic bearing characteristics:



PTFE: Polytetrafluoroethylene, English name: Polytetrafluoroethylene, abbreviated as PTFE. Also known as Teflon, Teflon, Teflon, Teflon, Defluon This material has a non-stick coating and easy cleaning properties. It has the characteristics of acid and alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance, and its friction coefficient is extremely low, so it can be used as a lubricant, and it has also become an ideal coating for easy cleaning of the inner layer of water pipes.
advantage:
High temperature resistance: The working temperature can reach 250 ℃.
Low temperature resistance: It has good mechanical toughness; even if the temperature drops to -196 ℃, it can maintain 5% elongation.
Corrosion resistance: For most chemicals and solvents, it is inert, resistant to strong acids and bases, water and various organic solvents.
Weather resistance: Aging life in plastic.
High Lubrication: The coefficient of friction in solid materials is very low.
Non-adhesion: It is a very small surface tension in solid materials and does not adhere to any substance.
Non-toxic: It is physiologically inert, and has no adverse effects as long as it is implanted into the blood vessel and organs.
Electrical insulation: Can withstand 1500 volt high voltage electricity.
Cons:
Low compression resistance, plastic deformation under long-term continuous load.
Not sticky, limiting its industrial application. It is an excellent release material, which makes it extremely difficult to adhere to the surface of other objects.
The coefficient of linear expansion is high, 10 to 20 times that of steel, which is larger than most plastics. Its coefficient of linear expansion is deformed with changes in temperature.
