From your common frying pan to industrial chemical handling equipment, PTFE is a synthetic polymer that is found in numerous types of products. While it is common, PTFE is notoriously hard to bond so choosing the right adhesive and applying it correctly is imperative.
PTFE or polytetrafluoroethylene is a synthetic high-performance polymer known for its non-stick properties. In more common terms, it is referred to as Teflon®. It is a high-density material with electrical insulation properties. It also has great resistance to high temperatures and many chemicals.
Because of these properties, PTFE is often used in harsh environments or more extreme applications. One of the most well-known applications for PTFE is non-stick pans, but it is also commonly used in electrical components, chemical processing equipment, pipework, and seals and gaskets.
While PTFE's non-stick properties and high chemical resistance make it great for applications where many other materials would fail, those same properties make it much harder to bond with an adhesive. PTFE also has a low surface energy that contributes to its bonding difficulties.
Together, all these properties can decrease the effectiveness of adhesives. Adhesives are more likely to struggle to penetrate and adhere to the surface, especially in more trying environments. As a result, lasting and high-strength bonds can be difficult to form and bond failure may occur. While gluing Teflon can pose a challenge, it doesn't mean it is impossible. There are some PTFE adhesives available that will form bonds with proper surface preparation or the right primer.
While the best glue for PTFE will vary from application to application, there are some products you can test for your application. Permabond has a couple of adhesives that it says can bond PTFE including TA, TA, TA, and TA. These acrylic adhesives have toughened formulas that are better suited for materials with low surface energy. Depending on the specific application, Infinity Bond MMA 500 may also be a potential option. It is made specifically for bonding difficult plastics.
Keep in mind that while these PTFE adhesives are available, they may not work for your specific needs. Some of these adhesives may not be able to form bonds with a shear strength above two newtons, especially in more challenging conditions. Always test the adhesive to see how it performs in your bonding environment to avoid unforeseen bond failure. If you are not sure where to begin, we may be able to provide you with more guidance or a product recommendation.
Finding the right Teflon adhesive is just the beginning. Before you can even test the adhesive, always begin by implementing proper safety standards such as wearing protective clothing and working in a well-ventilated area as needed.
The next step is prepping the surfaces that will be bonded. Because PTFE is generally more difficult to bond, surface preparation is even more important. The exact procedures vary from product to product, so always follow the manufacturer's instructions for the best results.
Surface preparation for gluing PTFE often involves cleaning or degreasing the substrates to start. The PTFE will often need to be chemically etched "pickled" with fluorocarbon etchants such as Tetra-Etch. Unfortunately, corona treatment, plasma treatment, and abrading the surface are almost no help when it comes to trying to bond the non-stick surface. In many cases, a primer will also be recommended.
Because it is so difficult to get lasting and strong bonds when gluing PTFE, you should not only follow the recommended surface preparation procedures to a T, but also test the adhesive in the bonding environment. A product that works initially may fail when exposed to stress in its normal environment.
When you are done applying the PTFE glue, make sure you tightly seal and properly store any remaining product. Adhesives that are not stored correctly or that are used past their shelf life date may be ineffective.
Adhesive tapes are often essential in both household and industrial settings. There are a variety of tapes available on the market, but one of the most versatile is PTFE (Teflon) adhesive tape.
This type of tape has a wide range of applications, and it can be used for both temporary and permanent fixes. If you’re looking for an adhesive tape that can handle a variety of tasks, then PTFE is the right choice for you. In this article, we’ll discuss everything you need to know about PTFE adhesive tapes.
Teflon is a brand name for a synthetic polymer known as polytetrafluoroethylene (PTFE). Teflon was first discovered in by Roy J. Plunkett at DuPont when he observed that a fluorocarbon-based material had unexpectedly solidified.

Teflon is known for its extreme durability and resistance to chemicals, heat, and friction. These properties make it an ideal material for a wide range of applications, including non-stick cookware, electrical insulation, and automotive parts.
Teflon or PTFE adhesive tapes are made from a material called polytetrafluoroethylene, or PTFE for short. This synthetic fluoropolymer is known for its non-stick properties, making it an ideal choice for a variety of applications.
Teflon adhesive tapes are available in a variety of widths and lengths and can be customized to meet the specific needs of each application. Teflon adhesive tapes are also available in a variety of colours, including clear, white, and black. Teflon adhesive tapes are made by bonding PTFE to a suitable substrate, such as cloth, paper, or metal foil.
Teflon (PTFE) adhesive tapes have a number of excellent properties that make them ideal for a variety of applications. Some of the most important characteristics of Teflon adhesive tapes include:
PTFE adhesive tape can protect polybag and shrink wrap equipment by forming a protective barrier that also acts as an adhesive. The tape has different sizes to fit your needs, so you’ll be able to protect these items from any potential damage with ease.
Their adhesive can last twice as long as acrylic adhesives. It can withstand temperatures from -73°C to 260 °C, which means it’s perfect for any cold-weather application and won’t fail you in the middle of winter.
The list of PTFE adhesive tape benefits is endless. It’s an ideal choice for any application that requires a robust, reliable, and versatile cohesive force to keep things stuck together—from industrial machinery to construction equipment or even food storage containers!
PTFE zone tape is an innovative new product that’s perfect for any application that requires a reliable adhesive force. Zone tapes have a PTFE coated woven glass surface with a one-sided etched treatment for edge tapes, leaving an open area of usable fabric absent of adhesive. This gives users the ability to heat-seal, laser-cut, or die-cut without adhesive contamination! PTFE zone tape is also perfect for gaskets or used as a release liner in laminating processes.
Skived PTFE tape is made by slicing a very thin layer of PTFE from a block of the Teflon material. This tape is used in applications that require an incredibly thin PTFE tape, such as in the electronics industry.
Skived PTFE tape has a wide range of uses, including electrical insulation tape, masking tape for circuit board plating, and more. It is used for the high-temperature resisting, acid-resisting, and alkali resistant shielding of low surface friction on heating panels as well as protection from electrical insulation applications that meet class H requirements. This material is also removed cleanly after use.
Teflon adhesive tapes are used in a variety of industries, from aerospace to electronics. Some of the applications where they are widely used are:
Before you apply the PTFE adhesive tape, it is important to clean the surface. The surface should be clean, dry, and free of debris.
To apply the tape, start at one end and slowly wrap it around the surface. Be sure to overlap the edges of the tape by at least 1/8″. Once the tape is applied, use a roller or your fingers to smooth out any bubbles. For best results, allow the tape to cure for 24 hours before use.
At Canada Plastics & Belting Inc., we carry a wide range of PTFE adhesive tapes. We specialize in bespoke-cut tapes, and we design and cut tape orders to the precise demands of our clients. We offer customized cutting and slitting services, so you can buy exactly what you need.
