Description:Fluorine rubber has a wide temperature range,
usually from -20 degrees Celsius to 250 degrees Celsius,
and can be used at 280 degrees or 300 degrees for a short time.
Fluorine rubber also has better pressure resistance.
Although it is not as good as HNBR and NBR,
HNBR and NBR are not suitable for high temperature environments.
Fluorine rubber also has good oil resistance, and is often used as
an oil-resistant sealing material for automobile fuel tanks or petroleum machinery.
Fluorine rubber is also resistant to acids, alkalis and various chemical substances.
Because of its long service life, it is also known as the first choice
for sealing materials that contact various chemical media.
As the most commonly used seals, O-rings are often used for dynamic or static seals
such as mechanical seals and auto parts seals.
