Polytetrafluoroethylene (PTFE) sheets, also known as Teflon or Fluon, are sheets made from polytetrafluoroethylene resin.
Feature
Temperature Resistance: Can be used continuously over a temperature range from -180℃ to +250℃. It remains non-brittle at low temperatures and maintains stable performance at high temperatures.
Chemical Stability: With the exception of molten sodium metal and liquid fluorine, it is resistant to corrosion by all other chemicals, including strong acids, strong bases, and aqua regia. It remains unchanged even when boiled in water.
Electrical Insulation: Possesses excellent electrical insulation performance, with a low dielectric constant and low dielectric loss, as well as high dielectric strength.
Low coefficient of friction: The coefficient of friction is extremely low, offering excellent self-lubricating properties and minimal wear.
Non-stick property: The surface tension is extremely low, preventing any substances from adhering to it, making cleaning and demolding easy.
Weather resistance: Excellent resistance to ultraviolet radiation and atmospheric conditions, making it resistant to aging or degradation.
Flame retardancy: Exhibits excellent flame retardancy and is not easily combustible.Specifications
Molded boards: Common size specifications include 400mm×400mm and 500mm×500mm, with thicknesses ranging from 3mm to 120mm.
Turning plates: The width typically ranges from 50 mm to 2200 mm, and the thickness is between 0.3 mm and 8 mm.Application areas
Chemical industry: Used as linings for equipment such as reactors, pipelines, and valves, as well as for seals and lubricants, to resist the corrosion of various corrosive media.
Electrical and electronic fields: It can be used as an insulating layer for wires and cables, as well as insulating components for electrical instruments and meters, leveraging its excellent electrical insulation properties.
Mechanical field: Used as a lubricant and wear-resistant material for bearings, sliders, guide rails, and other components, reducing friction and wear.
Medical field: Due to its non-toxicity and physiological inertness, it can be used for long-term implantation as artificial blood vessels and organ replacements, and is also employed in sealing and insulating components of medical devices.
Aerospace field: Due to their excellent performance, they are used in the manufacture of aircraft and spacecraft components, such as seals and insulating materials.
In the construction field, it is often used as stair treads or sliding guides, leveraging its low coefficient of friction and weather resistance.

FAQ
Can I take a sample for testing?
Yes, samples can be sent for testing before placing a bulk order.
Do you have a pre-shipment inspection procedure?
Yes, we always test the product before delivery.
Can I have my own custom-made product?
Yes. We can provide OEM and ODM services, including design, logos, packaging, and more.
What’s the difference between CBN grinding wheels and diamond grinding wheels?
CBN (cubic boron nitride) is suitable for grinding high-hardness alloy steels;
Diamond grinding wheels are suitable for grinding brittle materials such as cemented carbides and ceramics.
