PTFE Advanced Engineering Grade Plastic
Alro Plastics offers PTFE or TFE (polytetra-fluoroethylene), a very dense material at f 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 compared to other engineering-grade materials.
Mechanical properties of PTFE 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). PTFE is also offered in FDA compliant grades for food grade applications. Unfilled PTFE sheet, made from virgin PTFE resin, is extremely soft and formable. It is often used for chemical-resistant seals and gaskets.
