There is generally some confusion concerning the basic principle difference in between probably the most standard grades of PTFE, generally referred to as Teflon: Virgin Grade, and Mechanical, or Reprocessed Grade. This details will help you comprehend these two sorts and their numerous applications, and consequently spend less you time researching the information.
Material and applications
PTFE ( polytetrafluoroethylene ) is typically a sort of plastic material most generally recognised since the producer name Teflon®. PTFE Fabric resins possess a ongoing temperatures rating of 260°C (500°F). mechanised components start to degrade above this point.
Both Virgin and mechanised grades are 100% PTFE product and have comparable substance properties. they are the two unfilled types of PTFE. Other sorts are on the marketplace with fillers such as carbon, bronze, or cyrstal glass to further improve performace for specific applications.
Mechanical PTFE is definitely an economical, reprocessed PTFE with slightly reduced bodily components than virgin grade. it may be referred to as "recycled" or "reclaimed". Reprocessed product is additional through the producing process; typically merely a tiny percentage however it varies. It is a whole great offer more economical than virgin. This could possibly be the grade employed for most applications, for much less demanding utilizes precisely where huge purity assets are not required, such as noncritical chemical, electrical, and mechanised applications. It carries an awesome offer better fixture on resistance and compressive durability than virgin grade. Not ideal for dishes contact.
Virgin PTFE is typically a increased grade, pure material, and is also a whole great offer more expensive. It is made without any recycled product added. It is chemically inert as an awesome offer as 500ºF, the instead best chemically resistant product available. Virgin carries an awesome offer better bodily components and retains versatility in reduced temperatures. It is typically an awesome electric powered insulator, with huge dielectric properties. It is FDA authorized and is also employed within your pharmaceutical, dishes and beverage, and make-up industries. It is generally employed for health care or electric powered applications. Virgin carries an awesome offer better friction characteristics, which could possibly be essential in some applications.
How would you already know in the event you have Virgin or mechanised PTFE Coated Fabric?
Distinguishing in between the two grades by sight is certainly not easy! in the direction of the naked eye, the two grades may glance identical.
Virgin grade is generally a purer bright when in comparison side-by-side, and should really really feel a whole great offer more smooth and slippery.
