Overview of pure and oily Teflon packing:
Pure and oily Teflon packing is one of the most important industrial equipment in the laboratory for sealing. This packing is also known as sealing yarn (PTFE). Teflon packing is made of Teflon fibers. The most important feature of Teflon sealing packing that distinguishes it; Obtain the necessary permits to work in a health environment. This industrial refractory is divided into two types in the structure: 1- Pure Teflon packing and 2- Oily Teflon packing.
1- Pure Teflon packing: This sealing packing is completely woven from pure Teflon fibers and has a very good chemical resistance as well as low coefficient of friction. Certain mechanical and static strengths are two other features mentioned for pure Teflon packing. But the most important issue is temperature tolerance; + 300 degrees Celsius is the amount of heat that this product can withstand. The most important applications of pure Teflon packing are the following:
The best choice in the field of sealing all types of engines, tanks and valves in sanitary environments
Used in food, pharmaceutical, centrifugal and piston pumps
2 – Teflon oil packing: In this type of Teflon packing, Teflon fiber is impregnated with silicone oil. Silicone oil is used to create lubrication and flexibility in this product. The presence of silicone oil prevents the shaft from deforming at high temperatures. Of course, the temperature tolerance of Teflon oil packing is 20 degrees Celsius higher than its prototype due to the presence of silicone oil and it is able to cover the heat well up to 320 degrees Celsius. The applications of oil Teflon packing are exactly the same as the applications and uses of pure Teflon packing that we discussed on this page.
