Teflon plastic (PTFE) is a type of plastic that has excellent heat resistance, chemical resistance, and abrasion resistance. This material has high chemical resistance and self-lubricating properties and is often used for bearing components, plastic gears, seal rings, etc.
The continuous use temperature is 260°C and the melting point is 327°C. Teflon (PTFE) resin has high cold resistance and maintains its durability even in low temperature environments down to -250°C. Although it can be used over a wide temperature range, it is also a material whose volume changes significantly with temperature. When incorporated into a product, it may expand and become incompatible depending on the temperature. In this case it will shrink, but will return to its original size once cooled. Teflon resin (PTFE) is a material that is easy to cut, but it is prone to burrs, so post-processing is required. Particular attention should be paid to the quality when polishing the holes through which the liquid passes.
Mechanical Strength of Teflon (PTFE) Plastic
Teflon resin (PTFE) has excellent impact resistance (Izod impact strength 150 to 160 J/m). It won't crack or chip on impact, but it is easily deformed by impact and may leave a dent if dropped.
Heat resistance
Teflon (PTFE) is one of the most heat-resistant plastic materials, with a continuous use temperature of 260°C. It can be used at temperatures as low as -250°C.
Fireproof
Teflon plastic (PTFE) has a molecular structure that makes it difficult for it to combine with oxygen, making it a fire-resistant material that does not easily spread fire.
Slipperiness
Teflon plastic (PTFE) has a low coefficient of friction between plastics, making it easy to slide. It has excellent abrasion resistance and is used in sliding parts.

Precautions for use and handling of Teflon plastic (PTFE)
Since the dimensions are easily affected by temperature, the temperature must be adjusted before assembly. As the material is prone to burrs, post-processing is required.
2. Purpose
Food machinery, medical equipment parts, semiconductor equipment, liquid crystal related parts, rollers, scientific equipment.
3. Examples of use of Teflon (PTFE) processed products
1. Medical industry
Teflon (PTFE) is a type of plastic with excellent chemical resistance. It is resistant to many chemicals and has excellent heat resistance, making it suitable for high-temperature sterilization and cleaning, and for products used in medical settings. Examples include analytical equipment parts, artificial heart parts, tubing for hemodialysis systems, catheter parts, and endoscope parts. In some cases, syringes and tubes that were previously made from rubber or silicone are being changed to Teflon (PTFE) plastic.
2. Processing machinery
Teflon (PTFE) plastic is non-stick, waterproof, and oil-resistant, making it difficult for most substances to adhere to it. It has releasability (easy to peel off even if sticky) and does not leave behind highly viscous substances, so it is used in food manufacturing processes, machine printing, and mechanical parts such as mixers. Another benefit is that its non-stick properties make the cleaning process easier after use.
3. Semiconductor machinery and equipment
Teflon (PTFE) resin is primarily used in semiconductor manufacturing equipment, including chemical tanks, piping, pipe fittings, wafer carriers, valves, pumps, bellows, and diaphragms. Various chemicals are used in the semiconductor manufacturing process, including strong acids and strong alkalis, so parts exposed to these chemicals are made of Teflon (PTFE) resin, which has high chemical resistance.
