What fluoroelastomer examples are used in chemical processing?
Hey there! As a supplier of fluoroelastomer examples, I'm super stoked to chat with you about the various fluoroelastomers used in chemical processing. Fluoroelastomers are a group of synthetic rubbers that are known for their excellent resistance to heat, chemicals, and oils. These properties make them a top choice in many chemical processing applications. Let's dive right in and explore some of the most common fluoroelastomer examples used in this field.
Viton: The Heavy - Hitter in Chemical Processing
Viton is probably one of the most well - known fluoroelastomers out there. It's a brand of fluoroelastomer produced by Chemours. Viton has an outstanding resistance to a wide range of chemicals, including acids, bases, and solvents. In chemical processing plants, it's often used in seals, gaskets, and O - rings.
For instance, in the production of petrochemicals, where there are harsh chemicals and high temperatures, Viton seals ensure that there are no leaks in pipes and equipment. It can withstand temperatures up to 200 - 230°C continuously and even higher in short - term exposures. This heat resistance is crucial as many chemical reactions take place at elevated temperatures.
Another great thing about Viton is its resistance to swelling. When it comes into contact with chemicals, it doesn't absorb them and swell up, which could lead to a loss of seal integrity. This makes it reliable for long - term use in chemical processing environments.
Kalrez: High - Performance for Extreme Conditions
Kalrez is a perfluoroelastomer (FFKM) from DuPont. It's like the superhero of fluoroelastomers when it comes to extreme chemical and temperature resistance. In chemical processing, especially in high - purity and aggressive chemical applications, Kalrez is the go - to material.
In semiconductor manufacturing, where ultra - pure chemicals are used, Kalrez seals prevent any contamination. It can resist almost all chemicals, including strong oxidizing agents like fuming nitric acid. The high - purity nature of Kalrez also means that it doesn't release any particles that could contaminate the sensitive semiconductor wafers.
When it comes to temperature, Kalrez can handle even higher temperatures than Viton. It can operate at temperatures up to 327°C, which is pretty amazing. This makes it suitable for chemical reactions that occur at extremely high temperatures, such as in some specialized chemical synthesis processes.
Fluorosilicone Elastomers
Fluorosilicone elastomers are another interesting group of fluoroelastomers. They offer a unique combination of properties. You can check out more about Fluorosilicone Elastomer on our website.
These elastomers have good resistance to fuels, oils, and some chemicals, along with excellent low - temperature flexibility. In chemical processing, they can be used in applications where there are both chemical exposure and low - temperature requirements.
For example, in some refrigeration systems in chemical plants that use certain chemical refrigerants, fluorosilicone elastomers can be used in seals. Their low - temperature flexibility ensures that the seals remain effective even in cold environments, while their chemical resistance protects them from the refrigerants.
There are also specialized types of fluorosilicone elastomers. Conductive Fluorosilicone Rubber is one such type. It has the added property of electrical conductivity. In chemical processing, this can be useful in applications where static electricity needs to be dissipated, such as in some powder handling processes where a build - up of static could be a safety hazard.
Adhesive Fluorosilicone Rubber is another variant. It has good adhesive properties, which can be handy in bonding different parts in chemical processing equipment, like attaching gaskets to metal surfaces securely.
Technoflon: Italian Excellence in Chemical Resistance
Technoflon is a fluoroelastomer produced by Solvay. It offers a high level of chemical resistance, similar to Viton but with some unique features. It has good resistance to a variety of organic solvents and can be used in applications where there is a need for resistance to both chemicals and ozone.
In the pharmaceutical industry, which is part of chemical processing in a way, Technoflon can be used in equipment seals. The production of pharmaceuticals often involves the use of organic solvents and strict hygiene requirements. Technoflon's chemical resistance ensures that it can withstand the solvents used in the manufacturing process, and its low - extractable nature makes it suitable for use in a clean and hygienic environment.
Choosing the Right Fluoroelastomer
When selecting a fluoroelastomer for chemical processing, there are several factors to consider. First, you need to think about the chemicals that the elastomer will come into contact with. Different fluoroelastomers have different levels of resistance to various chemicals. For example, if you're dealing with strong acids, Kalrez might be a better choice than some other fluoroelastomers.
Temperature is another crucial factor. If the application involves high - temperature processes, you'll need an elastomer with good heat resistance like Viton or Kalrez. Low - temperature applications, on the other hand, call for elastomers with good low - temperature flexibility like fluorosilicone elastomers.
Cost is also a consideration. Some high - performance fluoroelastomers like Kalrez are more expensive than others. You need to balance the performance requirements with the budget.
