Teflon PTFE virgin and Mechanical Degrees, What's the difference?

Often there is some confusion about the difference between the most common types of PTFE, often referred to as Teflon: Virgin grade, and mechanical degrees or reprocessed. This information will help you to two of these species and their various applications and time-saving, information.

Materials and Applications

PTFE Tubing

PTFE (polytetrafluoroethylene) is a type of plastic most often as the brand name Teflon ®. PTFE resins are a continuousTemperature range of 260 ° C (500 ° F). Mechanical properties begin to deteriorate at this point.

Teflon PTFE virgin and Mechanical Degrees, What's the difference?

Both Virgin and the mechanical qualities are 100% PTFE and have similar chemical properties. These are the two types of unfilled PTFE. Other guys are improving with fillers such as coal, bronze, glass or performace for some applications.

Mechanical PTFE is a low cost, recycled PTFE with a little 'physical properties of lower-class virgin. It 'also known as"Recycling" or "liberated". The recycled material is added during the manufacturing process, usually a small percentage, but it's different. AND 'cheaper than virgin. This is the class for most of the applications are used for less demanding applications that require high purity materials, such as the critical chemical, electrical and mechanical applications. It has better wear resistance and compressive strength class virgin. Not suitable for contact with food.

Virgin PTFE is a higher grade,pure matter, and is more expensive. It 'was recorded without any recycled material. E 'chemically inert up to 500 º F, the best chemically resistant material. Virgin has better physical properties and retains flexibility at low temperatures. It 's a good electrical insulator with high dielectric properties. E 'approved by the FDA and is used in pharmaceutical, food and beverage, and cosmetics. Often in medical applications or electricity is used. Virgin has a betterfriction properties, which may be important in some applications.

How do you know if you have Virgin PTFE or mechanical?

The distinction between the two types of eyes is not easy! To the naked eye, the two types look identical.

Virgin class is often a pure white compared side-by-side, and should be more smooth and slippery.

PTFE is commonly known as Teflon ®, which is actually a DuPont trademark for its brandPTFE resin. Several trademarks are used by other manufacturers, such as Fluon ® and Dyneon ®.

If you like to ASTM D1710, ASTM specifications to see extruded polytetrafluoroethylene (PTFE) Rod, thick-walled tubes and basic shapes.
