Advantages and disadvantages of peroxy high fluorine rubber
Peroxy high fluorine rubber has the following advantages and disadvantages:
Advantages:
Excellent high temperature resistance: It can work stably for a long time at a higher temperature, generally can be used for
a long time at 200℃ -250 ℃, and some special formula products can even work for a short time at a higher temperature, for
example, it can maintain good performance at about 300℃, which makes it unique in the application of high temperature
environment. For example, high-temperature components seals in the aerospace field, seals around the engine, etc.
Good chemical resistance: for most oils, organic solvents (except ketones, low molecular weight esters and nitro-containing
mixtures), acids, etc., have a strong resistance, can maintain stable performance in harsh chemical environments, suitable for
the chemical industry of reactors, pipelines, valves and other equipment sealing.
Excellent electrical insulation performance: Although its electrical performance in high frequency, high voltage occasions may
not be as good as other materials, but in low frequency, low voltage occasions, its electrical performance is still reliable
Excellent ozone resistance and weather resistance: in the outdoor long-term exposure or in the ozone environment, it is not
easy to appear aging, cracking and other phenomena, long service life, can be used for outdoor sealing, rubber products, etc.
Good mechanical properties: including high tensile strength, hardness, tear strength, etc., can withstand large mechanical
stress to ensure that it is not easy to damage during use, and can be used to manufacture rubber parts that bear higher loads.
Cons:
Low temperature performance is poor: in a low temperature environment, peroxo high fluorine rubber will become hard and
brittle, elasticity is reduced, usually the limit temperature of its ability to maintain elasticity is about -15 ° C to -20 ° C, which
limits its application in cold areas or low temperature conditions, such as in the polar environment equipment seal use may
cause problems.
High processing difficulty: Due to the characteristics of its molecular structure, the processing process of peroxo high-fluorine
rubber is relatively complex, and the processing technology and equipment are required to be higher, and the processing cost
is also increased, which affects its wider application to a certain extent.
Expensive: The high cost of raw materials, coupled with the complex production process and strict quality control requirements,
make the product price of peroxo high fluorine rubber is high, which may limit the scale of its use for some cost-sensitive areas.
