O-rings made of fluororubber material, commonly referred to as fluororubber O-rings, are annular products made from fluororubber. As industrial development progresses, fluororubber O-rings are widely used in automotive, electronic, aerospace, shipbuilding, and other environments that require high precision, high resistance to high temperatures, and excellent wear resistance under stringent conditions. With the advancement of industry, fluororubber materials are continuously being improved and innovated. Below is a list of the performance and applicable scopes of commonly used fluororubber materials.

Fluororubber

Rubber containing fluorine has various types depending on the fluorine content (i.e., monomer structure). It exhibits superior high-temperature resistance compared to silicone rubber, and some varieties offer resistance to chemicals, most oils and solvents, weathering, and ozone. However, it has poor cold resistance, with a general operating temperature range of -20 to 250°C. Special formulations can withstand temperatures as low as -40°C.

Hardness: 50-90 degrees.

Color: Usually made in black, blue, brown, green, and can also be customized to the customer's specified color.

Advantages: Resists heat up to 250°C and offers resistance to most oils and solvents, especially all acids, aliphatic hydrocarbons, aromatic hydrocarbons, and vegetable oils.

Disadvantages: Not recommended for use with classes, low molecular weight classes, and mixtures thereof.

Fluorinated O-ring Applications: Sealing for automobiles, motorcycles, diesel engines, and fuel systems; seals for chemical plants.
