Perflurane rubber properties:
FFKM perflurane rubber material is the best rubber material with high temperature resistance, strong acid and alkali resistance and organic solvent resistance in all elastic sealing materials. Perflurane rubber can resist strong acids, alkali, organic solvents, ultra-high temperature steam, ethers, ketones, esters, nitrogen compounds, hydrogen carbide, alcohols, aldehydes, furans, amine compounds and other more than 1600 kinds of chemical solvents corrosion, high temperature resistance up to 320ºC, FFKM perflurane parts have been in many industries with nearly 40 years of practical application experience.
The basic concept of perflurane O-rings
Perflurane O-ring is a kind of sealing element with high performance. It is mainly made of perflurane rubber material, which has excellent chemical resistance, high temperature resistance and low temperature flexibility.
Material property
Chemical resistance: It can resist the erosion of most chemical substances, including strong acids, strong alkalis, strong oxidants and so on. For example, in a variety of highly corrosive chemical production environments, it can maintain stable performance and will not be easily damaged by corrosion.
High temperature resistance: It can work stably for a long time under the temperature environment of up to 300ºC or even higher. Whether it is in the high-temperature industrial furnace equipment, or in the sealing parts of high-temperature components such as automotive engines, it can play a reliable sealing role.
Low temperature flexibility: at very low temperatures, it can still maintain good elasticity and sealing performance, and can generally be used normally at -40 ° C or even lower temperatures.
The following are some common product parameters of perflurane O-rings:
1. Size parameters
Inner diameter: can range from a few millimeters to hundreds of millimeters, common specifications such as 10mm, 20mm, 50mm, etc., can meet the sealing needs of different equipment interfaces.
Section diameter: Usually between 1mm and 10mm is more common, such as 2mm, 3mm, 5mm, etc., different section diameters are suitable for different sealing pressure requirements.
2. Physical performance parameters
Hardness: Shore hardness is generally between 50A and 90A, according to the specific application scenario and sealing requirements to choose, the harder O-ring is suitable for high pressure sealing, the softer is better when sealing irregular surfaces.
Tensile strength: usually around 5MPa to 20MPa, with good tensile resistance, to ensure that it is not easy to be pulled during installation and use.
Elongation at break: generally can reach 100% to 500%, so that it has good elasticity and flexibility, can adapt to a variety of different installation conditions and deformation in the working environment.
Three, temperature performance parameters
Long-term use temperature range: it can usually work stably between -40 ° C and +300 ° C, and O-rings made of some specially formulated perflurane materials can even be used for a short time at higher temperatures.
Instant temperature resistance: it can withstand temperature shocks of up to 350 ° C or even higher in a short time without immediate damage, ensuring reliability in some special conditions.
Fourth, chemical resistance parameters
It has good tolerance to various strong acids and bases, such as being able to be used in sulfuric acid (98% concentration), hydrochloric acid (37% concentration), sodium hydroxide (50% concentration) and other environments for a long time without being corroded.
It also has strong resistance to various organic solvents such as acetone, toluene, ethanol, etc., and has minimal changes in size and performance after soaking in these solvents.
5. Compression permanent deformation parameters
Under the specified temperature and pressure conditions, after a certain period of compression, its compression permanent deformation rate is low, generally between 10% and 30% (according to different test standards and conditions vary), which ensures that it can always maintain good elasticity and sealing effect in the long-term sealing process.
Seal application and typical application conditions include:
Chemical industry: Used for the sealing of various chemical pipelines, valves, reactors and other equipment, to ensure that there will be no leakage problems in the chemical production process, to ensure production safety and environmental safety.
