PTFE
Shop qualified PTFE sheets, rods and parts. PTFE is a kind of engineering plastics, and the chemical name of PTFE is polytetrafluoroethylene. It is non-toxic under normal conditions. PTFE also known as Teflon, is a synthetic polymer material that is resistant to alkalis, acids and organic solvents. The coefficient of friction of PTFE is very low, so it is often used as a coating for the inner layer of non-stick pans and water pipes.
What is PTFE？
PTFE is a polymer chemical material containing polytetrafluoroethylene. WIt is widely used in packaging, electronics and electricity, chemical energy, corrosion-resistant materials .
What is the features of PTFE？
Excellent corrosion resistance, able to withstand in addition to molten alkali metals;
It has strong insulation resistance and is not affected by the environment and frequency, and the volume resistance can reach 1018 ohm cm;
PTFE material also has excellent high and low temperature resistance, little change in temperature, wide temperature range, usable working temperature -190℃～+250℃;
PTFE material has unique self-lubricating property and has the smallest coefficient of friction among plastics;
PTFE material has a prominent surface that is not sticky;
PTFE material also has good atmospheric aging resistance, radiation resistance and low permeability, and its surface properties remain unchanged after long-term exposure to the atmosphere;
PTFE has non combustibility , the oxygen limit index is below 90, if the open flame is removed, the PTFE material will not continue to burn.
What are PTFE used for？
Due to the above characteristics of PTFE material, it has a wide range of uses. Usually we make PTFE sheets, PTFE tubes, PTFE rods, PTFE films, various special-shaped parts, and can also be formed by pushing or extrusion for high temperature. When you need the PTFE products ,just tell us your detailed request , we will give a prompt attention and good offer .

Is Teflon and PTFE the same thing？
Teflon is another name for polytetrafluoroethylene, and many clients also call it Teflon, because Teflon is a registered trademark of DuPont, and polytetrafluoroethylene plastic was invented by DuPont in the United States, so many people later called it Teflon.
Is PTFE harmful to humans？
PTFE is a high and low temperature resistant engineering plastic. Qualified and impurity-free PTFE will not cause any allergic reaction to people, and it will not be toxic. High temperature decomposition of any plastic will be toxic. PTFE is known as the king of plastics. The decomposition temperature is around 400 degrees. Generally, it is almost non-toxic within 200 degrees, and 327 degrees is its melting temperature.
What is characters of PTFE sheets and rods？
PTFE sheets and rods can be used in a wide range of temperature -200 degree to +260 degree .
They are basically resiatnt to all chemicals except some fluorides and alkaline metals.
PTFE sheets and rods have excellent mechanical properties including corrosion resiatnace especially for bending and winging applications.
They have outstanding flame retardance , which conforms to ASTM D635 and D470 test procedures .
They have insulating properties and extremely low water absorption .
Any points need to be attentioned when process the PTFE sheets？
When the PTFE sheet is milled by CNC machine , it is very easy to form burrs on the edge of the board, so some special methods must be used for processing.
First ,the knife is milled in a counterclockwise direction, which can effectively reduce the burr, or customize the knife with the opposite pattern to the conventional milling cutter; Secondly ,the phenolic fiber board is sandwiched between the plate and the plate; Thirdly , if with a die punch , the edge is very smooth to achieve the ideal processing state.
Is PTFE FDA approved?
Yes, PTFE (polytetrafluoroethylene) is approved by the FDA for use in food-contact applications. PTFE is a type of plastic that is known for its non-stick properties and is often used to coat cookware and other kitchen appliances.
Does PTFE leach into food?
No, PTFE is a non-toxic material and does not leach into food. However, it should be noted that PTFE can decompose if heated to high temperatures, which can potentially result in the release of toxic gases. Therefore, care should be taken to ensure that PTFE-coated cookware is not overheated.
