Introduction of PTFE

Polytetrafluoroethylene (PTFE) is a high-performance synthetic fluoropolymer known for its exceptional chemical resistance, non-stick properties, and wide temperature range stability. PTFE is a type of plastic with remarkable characteristics that make it suitable for a variety of industrial, commercial, and consumer applications. It is commonly recognized by the brand name “Teflon,” which is often used to refer to PTFE coatings and materials.

Please note that PTFE does not exhibit significant shrinkage during molding, which is why the shrinkage rate is listed as “N/A.” Additionally, PTFE does not require drying prior to processing.

FAQ About PTFE Plastic Material

Teflon is a brand name associated with PTFE materials and coatings, but PTFE refers to the polymer itself.

PTFE’s non-stick properties arise from its extremely low coefficient of friction, preventing materials from adhering to its surface.
