PTFE, short for polytetrafluoroethylene, is a synthetic fluoropolymer derived from tetrafluoroethylene. This high-performance engineering plastic features outstanding non-stick performance, superb heat and chemical resistance, plus an ultra-low friction coefficient, and it covers a wide array of uses:
Non-stick kitchenware
It serves as the mainstream non-stick coating for frying pans, flat griddles and baking sheets.
Industrial manufacturing
Thanks to its chemical inertness and anti-adhesive traits, PTFE is adopted for lining pipes, storage tanks and vessels. It also creates smooth non-stick surfaces on conveyor belts and chute liners.
Electrical insulation
With superior dielectric properties, PTFE perfectly insulates wires, cables and connectors for diverse electronic and electrical equipment.
Sealing components
Its tolerance to harsh chemicals and high temperatures makes it ideal for fabricating seals, gaskets and O-rings in automotive, aerospace and machinery industries.
Medical devices
Owing to great biocompatibility, low friction and corrosion resistance, PTFE is made into catheters, surgical tools and prosthetic implants.
Filtration industry
Hydrophobic and chemically stable PTFE membranes and filters are widely used in air purification and water treatment systems.
