Aflas® O-Rings
Aflas® O-rings are a copolymer of tetrafluoroethylene (TFE, FEPM) and propylene with a fluorine content of approximately 54%, also known as TFE/P. The product provides effective sealing, preventing leaks of both liquid and gaseous fluids. It guarantees high performance, reliability and durability in harsh conditions across various industrial applications.
Aflas® O-rings - Advantages and properties
The Aflas® O-ring is an elastomeric compound characterized by excellent performance and properties. It prevents medium leaks in environments under varying pressures and temperatures. Discover its advantages and properties, here they are:
Chemical compatibility
TFE/P O-rings are a specialized type of seal resistant to degradation caused by aggressive chemicals. Thanks to the combination of a tetrafluoroethylene and propylene copolymer characterized by very good chemical resistance, it is used in demanding industrial conditions. The polymer structure composed of fluorinated and hydrocarbon segments provides appropriate resistance to various chemicals. The product has good resistance to brake fluids, shows resistance to petroleum, oils (including synthetic, vegetable, gear oils), acids and alkalis.
Withstands high temperatures
This type of sealing rings is characterized by a wide operating temperature range, which is from 25° C to +230° C. Due to the presence of fluorine atoms in the polymer, Aflas O-rings perform excellently in high-temperature applications, which significantly affects their service life.
Resistance to aging
The O-rings are insensitive to oxidative attack, allowing them to maintain performance over a long time.
Electrical insulating properties
TFE/P sealing rings have the ability to effectively resist electrical current.
Resistance to steam and amine corrosion
Resistant to amine corrosion inhibitors and steam corrosion, which allows them to be used in applications where sealing rings come into contact with hot steam.
Moreover, TFE/P rubber is resistant to petroleum, vacuum, and also exhibits excellent resistance to ozone and weathering. It shows a low level of deformation, therefore it retains its shape and sealing effectiveness even under pressure. Additionally, it is characterized by low gas permeability.
Aflas® O-rings - Applications
Aflas O-rings, thanks to their thermal and chemical resistance, perform excellently in many industrial applications. The sealing rings are made of high-quality materials that have the ability to withstand harsh conditions in industries such as:
-
chemical processing (pump seals, mixers, valves)
-
automotive industry (seals of fuel injectors, turbocharger hoses)
-
oil and gas (drilling tools, valves)
-
power generation (steam installations and hot steam)
-
pharmaceutical sector (liquid transport systems, cleaning systems)
-
mining and drilling sector
-
food processing
O-rings resistant to steam, acids and bases available in the Power Rubber store
Aflas® TFE / P O-rings are sealing rings that are characterized by very good chemical resistance due to a wide range of chemical substances (resistant to engine oils, phosphate esters, amines, steam and hot water, acids, alkalis, etc.). Our products are extremely durable and also provide reliable sealing in industries operating in high-temperature environments and/or with corrosive chemicals.
Chemical, thermal and steam resistance makes TFE/P an alternative to O-rings made of fluorocarbon rubber FKM (Viton®). They provide better resistance to alkalis, amines, acids, gases, H2S (hydrogen sulfide) vapor and radiation.
