PTFE or TFE (polytetra-fluoroethylene), is a very dense material having a density of 2.13 – 2.19 grams/cc. PTFE is well known for its chemical resistance. It is insoluble in all organics with the exception of a few exotics. Electrical properties are excellent. Impact strength is high but its resistance to wear, tensile strength and creep resistance are low in comparison to other engineering materials.
Mechanical properties can be improved by adding fillers such as glass fibers, bronze, carbon, and graphite. PTFE has an extremely low coefficient of friction. Very few materials will stick to it. It has useful properties from cryogenic temperatures up to 260oC (550oF).
Pharmaceutical and biopharmaceutical manufacturing facilities depend on PTFE components to allow them to the flexibility to produce multiple products while meeting needs for product purity, cleaning, wear and low maintenance costs.
PTFE is available in FDA compliant grades.
