PTFE, known in full as polytetrafluoroethylene, is a synthetic fluoropolymer applied in many areas. The compound was discovered in the late 1930s and has since then developed a wide range of applications. PTFE is used to manufacture various types of products, including Teflex filled PTFE gaskets and sheets. This post covers PTFE gasket sheets.
What is a gasket?
A gasket is a sealing product used to fill the space between a couple or more mating surfaces. It can also be defined as a combination of materials fastened between separate mechanical members of a flanged joint that produces the weakest link. The role of a gasket is to help prevent leakages from getting into or between joined objects under compression. These sealing products are usually made using deformable materials. The materials often come in the form of rinks or sheets, depending on the areas of application.
Gaskets can be manufactured from a wide range of materials. One of the most common forms of gasket materials is PTFE. PTFE gaskets are some of the most popular types of gasket sealants on the market.
Advantages of PTFE gaskets
PTFE gaskets offer a wide range of advantages. For instance, they provide superior chemical resistance. PTFE gaskets are also highly durable. The only elements capable of attacking PTFE gaskets are metals made from molten alkali and fluorine gas. Another benefit of PTFE gaskets is that they offer superior leak protection. PTFE gaskets offer low leaking rates, which makes them a great sealant.
Additionally, gaskets made from PTFE feature very dense sealing properties. This is why PTFE sealants are applied in a wide range of industries and areas. It is also worth mentioning that PTFE gaskets, whether rings or sheets, tend to adapt perfectly to the flange and are highly chemical resistant.
The downsides of PTFE gaskets
While PTFE gasket sheets and other PTFE sealing products are beneficial, they also suffer significant downsides. One of the downsides is that PTFE gaskets offer limited temperature resistance. They are also prone to creep.
Where to get the best PTFE gasket sheets
You can purchase PTFE gasket sheets online or offline. While online stores are highly advantageous, they are associated with a lot of risks. Regardless, there are some legitimate online stores where you can get high-quality PTFE gasket sheets. When it comes to the best place to purchase PTFE gasket sheets, the trick is to consider a company that works with or produces a wide range of PTFE products. This way, you can be sure that you are getting high-quality products and the company has ample experience. Teflex is one of the leading PTFE product brands on the market. It offers the best PTFE gasket rings and sheets for a wide range of applications.
Conclusion
Other than PTFE gaskets, the market features several different types of gaskets. They include rubber, graphite, and fiber-reinforced gaskets. These types of gaskets fall in the same category as PTFE gaskets as they are all non-metallic gaskets. There are also metallic types of gaskets. They can also be categorized based on their shape and form.
