FFKM perfluoroether rubber O-ring
It is a terpolymer of perfluoro(methyl vinyl) ether, tetrafluoroethylene and perfluoroolefin ether. Also known as perfluororubber
It has good weather resistance, odor resistance, water resistance and chemical resistance. It is suitable for alcohols and ketones, and can also be used for sealing in high temperature water vapor environment. It is suitable for sanitary equipment, automobile radiator and automobile braking system. Not suitable for food use or exposure to mineral oil. The general operating temperature range is -55℃~150℃.
The volume of the O-ring being squeezed into the gap should be less than the maximum allowable value for the rubber ring to be squeezed into. For different kinds of fixed sealing or dynamic sealing applications, O-ring provides designers with an effective and economical sealing element. The o-ring is a double-acting sealing element. The initial compression in radial or axial aspects upon installation, imparts the initial sealing capability of the o-ring itself. The sealing force generated by the system pressure and the initial sealing force are combined into the total sealing force, which increases with the increase of the system pressure. O-rings play a prominent role in static sealing occasions. However, o-rings are also often used in dynamic appropriate applications, but are limited by the speed and pressure at the seal.

The O-ring is a circular rubber ring with a circular cross-section. It is mainly used for mechanical parts to prevent leakage of liquid and gaseous media under static conditions. In some cases, it can also be used for axial reciprocation and low-speed rotation. Moving dynamic sealing element. According to different conditions, different materials can be selected to suit it.
O-rings are the most widely used seals in hydraulic and pneumatic transmission systems. Generally, O-rings are rarely used in rotary motion sealing devices. The O-ring is generally installed in the groove with a rectangular cross-section on the outer or inner circle to play a sealing role.
Nitrile-butadiene rubber is a synthetic rubber suitable for good corrosion resistance to oils, solvents, aromatic hydrocarbons, basic hydrocarbons, oil and natural gas over a wide temperature range. Good corrosion resistance to hydroxides, salts and near neutral acids. However, in strong oxidizing media, chlorinated hydrocarbons, ketones and lipids, its corrosion resistance is poor, and the recommended working temperature is 51℃~121℃.
Fluorine rubber compound is made by mixing binary and ternary fluorine raw rubber with compounding agent and vulcanizing agent. In addition to excellent heat resistance, medium resistance, and good physical and mechanical properties, it also has low compression set, good elasticity and long service life. Fluorine rubber has outstanding heat resistance (200 ~ 250 ℃), oil resistance, can be used to manufacture cylinder liner seals, rubber bowls and rotating lip seals, which can significantly improve the service time. Recommended working temperature -40℃~232℃.
The main professional processing equipment includes flat vulcanizer, injection molding machine, rubber and plastic pressurized kneader, rotorless vulcanizer, tensile testing machine...
