The surface of polytetrafluoroethylene after sodium treatment is hydrophilic, which can be bonded with ordinary glue to expand its application range.
Manufactured through an extrusion molding process, suitable for thinner sheet applications with high production efficiency.
In fact, it involves bonding a fiberglass cloth to one surface of a PTFE skived sheet, giving it the ability to adhere to other surfaces and simultaneously overcoming the limitation of PTFE’s inability to be welded.
This is commonly used in the electronics industry, particularly in the flat panel display industry. Due to PTFE’s excellent high-temperature resistance and impact resistance, it effectively prevents conductive adhesive from overflowing and contaminating the substrate.
It comes in a variety of colors and serves for identification or decorative purposes. It is commonly used for wire harness classification, pipeline identification in the chemical industry, and as a decorative waterproof layer in high-end buildings.
The glass fiber content is typically 15-30%, which greatly improves the mechanical strength of the PTFE sheet, making it twice as strong as general-purpose PTFE sheets and allowing it to maintain dimensional stability under high-pressure conditions.
With a copper powder content of 20-40%, it exhibits excellent thermal conductivity, 5-10 times that of ordinary PTFE sheets, but its corrosion resistance is reduced, limiting its use to neutral corrosive media.
Typically, increasing the graphite content by 10-25% enhances the self-lubricating properties of general-purpose PTFE sheets, resulting in a very low coefficient of friction. However, it also leads to lower hardness, and the price is slightly higher than that of standard general-purpose PTFE sheets.
Key Features of PTFE Sheet
Demonstrates favorable compressive and creep resistance at ambient temperatures, though may soften under elevated temperatures, suitable for low-stress applications.
Coefficient of friction (COF) as low as 0.04, featuring a smooth surface with self-lubricating properties that eliminate the need for external lubricants.
Exhibits corrosion resistance capable of withstanding aggressive agents and the majority of chemical media (pH 0-14).
Operational range spans from -200°C to +260°C for sustained service, with short-term exposure tolerance up to 300°C.

Typical Application Scenarios for PTFE Sheets
The most classic application of PTFE skived sheets is as a lining for chemical reactors, because PTFE has excellent chemical inertness and hardly reacts with any chemical substances, making it resistant to strong acids, strong bases, and other corrosive liquids. After adhesive treatment, the PTFE skived sheet adheres tightly to the reactor, and our professional technology ensures that it will not detach, extending the service life of your chemical equipment.
Due to PTFE’s extremely low coefficient of friction (only 0.04) and excellent self-lubricating properties, it is widely used in the manufacture of sliding bearings, guide rails, and piston rings, which can reduce equipment wear and save on production costs.
After processing, PTFE sheets can be used as substrates for printed circuit boards (PCBs), insulating gaskets, etc. This is because PTFE has excellent insulation properties, high temperature resistance, and very low dielectric constant and loss factor, resulting in minimal signal transmission loss.
There are specialized medical-grade PTFE materials used in high-end medical equipment, such as sterile seals or artificial heart valves. There is also food-grade PTFE, specifically labeled as harmless to humans, which can be used as a lining for household baking utensils, such as non-stick pans and oven trays.

Teflon and PTFE are essentially the same thing, both referring to the material polytetrafluoroethylene. The difference is that Teflon is a registered trademark, originally owned by DuPont, and now owned by Chemours, an independent company spun off from DuPont.
- Difficult to Process, High Cost: Due to PTFE’s unique properties, it has an extremely high melting point and requires special processing techniques, like “cold pressing,” which is time-consuming and requires specialized equipment. This makes PTFE expensive and challenging to process.
- Poor Creep Resistance: Compared to materials like nylon and PEEK, PTFE has lower hardness and rigidity. In practical applications, if PTFE is continuously under pressure, it may permanently deform over time.
- Decomposes and Releases Toxins at High Temperatures: When PTFE is exposed to temperatures above 260°C for long periods, it begins to break down and release toxic substances. At temperatures exceeding 350°C, the decomposition process accelerates, releasing harmful fumes.
- Non-Biodegradable: PTFE’s high thermal stability prevents it from naturally degrading. Recycling PTFE requires high temperatures, which can release toxic by-products, leading to environmental pollution and potential harm to human health.
The lifespan of PTFE depends on its application environment. Under clean conditions and normal operating temperatures, PTFE can last for 10-50 years. However, if it operates under high pressure for extended periods, its lifespan will be significantly shorter, possibly only 7-8 years, or even 4-6 years. Of course, this also depends on the grade of the PTFE material.
Currently, there are two methods for recycling PTFE:
- Mechanical Recycling: PTFE is ground into fine powder, compacted, and then sintered at a high temperature of 370°C.
- Chemical Recycling (also known as Pyrolysis): When exposed to temperatures over 400°C, PTFE decomposes into tetrafluoroethylene monomers.
After receiving the goods, you can quickly perform an acceptance inspection. First, check if the PTFE sheet is milky white and free of color variations. Secondly, measure its volume and weight to calculate the density of the PTFE sheet. If the density is within 2.1-2.2 g/cm³, it is considered acceptable. If you have sufficient time, you can immerse it in concentrated sulfuric acid solvent, observe it for 24 hours, then remove and weigh it. Compare the weight to the weight upon receipt; if the change rate is no more than 1%, and there are no cracks on the surface, it is considered acceptable.
PTFE, commonly known as “the king of plastics,” boasts excellent overall performance and is suitable for most applications. It also has a long service life, lasting 10-50 years or more. We can develop customized solutions for your specific project, providing personalized professional service to address your concerns.
Yes, PTFE is available in different grades, including general-purpose, food-grade, and medical-grade. Each grade is suitable for different applications. Furthermore, the raw materials for PTFE also vary, with different brands available from manufacturers such as DuPont and Daikin. In addition, there is both pure PTFE and recycled PTFE.
If you’re simply cutting PTFE sheets, you can do it yourself. For thin sheets, you can score the surface with a utility knife and then easily break it apart by hand; for thicker sheets, you’ll need a saw. First, secure the sheet, then mark the cutting line, and finally, saw along the marked line. However, if your project is large and involves a significant amount of PTFE sheets, you’ll need to use a CNC machine for cutting. This will greatly improve efficiency, but it may increase your costs.

PTFE Sheets
Polytetrafluoroethylene sheets are mostly called PTFE sheets. Or, you may also call them Teflon sheets. Of course, the two names refer to the same product except that “Teflon” is PTFE made by DuPont.
Generally speaking, these sheets are made from fluorine and carbon bonds. That is where it derives the name Polytetrafluoroethylene.
Due to the strong carbon bonds, they are considered high molecular sheets. A reason they are common in many applications today.
Types of PTFE Sheets Available
You can use broad criteria to classify Teflon sheets. It is due to the wide customization options.
Ideally, you may want:
- PTFE sheets with adhesive – they have adhesive substrate on one surface
- Cut to size PTFE sheets – the PTFE are cut according to your specific requirements
- Sheets with varying thickness – you may choose the PTFE sheet 3mm thick or 100 mm thick
In short, the available options depend on unique customization options. More importantly, this will also determine the PTFE sheet price.
General Purpose PTFE Sheet Material
Of course, the customization makes the Teflon sheets suitable for very specific applications. However, you may choose general-purpose PTFE sheets.
| Property of PTFE Sheet Material | Rating |
| Tensile strength | Poor |
| UV resistant | Good |
| Hardness | Medium soft |
| Impact strength | Good |
| Dimensions | Varies but it can be 6 by 6 inches to 48 by 48 inches |
Glass Filled PTFE Sheets
If you are looking for sheets with improved mechanical strength, impact, and abrasion resistance, then go for those with glass fiber. In most cases, these sheets have about 25% glass fibers
Features of Polytetrafluoroethylene Sheets
There are many reasons to choose these sheets:
- High melting makes the resin perfect for most continued service
- At high temperatures, PTFE material will remain stable. The temperature range is -200°C to +260°C.
- Known for superior anti-stick properties
- Superior insulation properties
- Co-efficient of friction is relatively low
- Better corrosion resistance than standard plastic material
- They are hydrophobic – they tend to repel water
- Chemically inert
- Are FDA approved
- Sensitive to gamma radiation
At times, your virgin PTFE sheet will not offer all these features. A reason you must reinforce the PTFE material. These sheets are made from 100% pure Polytetrafluoroethylene resin.
Let’s compare two interesting sheets:
| Virgin PTFE Sheet | Mechanical PTFE Sheet |
| · Made from 100% pure Polytetrafluoroethylene resin
· High physical properties · Normal application · No additional additives |
· Made from reprocessed Polytetrafluoroethylene resin
· Low physical properties · High-performance applications · Filled with additives to improve the properties |
Forms in Which you can Ship PTFE Sheets
You can get these materials as either flat or rolled. The packaging methods depend on the sheet thickness.
In most cases, the PTFE sheet rolls have a thickness of less than 0.093″. Otherwise, rolling Polytetrafluoroethylene sheets with higher thicknesses is not recommended.
Uses
You can machine or fabricate the PTFE material sheet to make many parts such as:
- PTFE gaskets
- PTFE bushing
- PTFE lining
- PTFE sliding plate
- PTFE electrical insulation parts
- PTFE washers
