Mechanical PTFE is an economical, reprocessed PTFE with slightly lower physical properties than virgin grade. It is also referred to as “recycled” or “reclaimed”. Reprocessed material is added during the manufacturing process; usually a small percentage but it varies. It is more economical than virgin.
This is the grade used for most applications, for less demanding uses where high purity materials are not required, such as noncritical chemical, electrical, and mechanical applications. It has better wear resistance and compressive strength than virgin grade. Not suitable for food contact.
