Properties of PTFE tapes

Properties of PTFE tapes

PTFE adhesive tapes are well known for their properties and applications. They are made with a synthetic polymer that can withstand temperatures ranging from -40°F to 350°F. PTFE tapes are also resistant to  corrosion, aging, chemicals and are used in high bar applications such as fuel injection systems. Moreover, PTFE tapes are both hydrophobic and oleophobic, which means that they are water resistant and cleanup is easier and more thorough. Finally, they are very easy to remove or reapply and they don’t leave any residues on surfaces.

There exist three different types of PTFE tapes. First, you have the PTFE fabric tape, coated with woven fiberglass. Its high dielectric strength and high temperature resistance is perfect for food applications and heat sealing.

Then, you have the PTFE adhesive tape, coated with woven fiberglass and acrylic adhesive. With a low dielectric strength and temperature resistance, it is mostly used for non-stick applications. They are very practical and easy to remove.

And finally, you have the PTFE coated glass tape, made with woven fiberglass and silicone adhesive. It has a higher dielectric strength than the PTFE fabric and the same heat resistance. It is used on smooth surfaces for non-stick and low friction applications.

Nowadays, PTFE Impregnated fiberglass tapes can be used in a wide range of industries. For PVC window manufacturing, they are applied to the weld plates to allow rapid heat transfer. In food processes, they enable the adhesion and transformation of ingredients like tortillas, bacon and cookies. In the manufacturing of packaging and plastic bags, they help with shrink film, blister packs, forms and much more.  Finally, they are perfect to insulate cables and connector assemblies in electronics. They can also be useful for hookup wires, coaxial cables and printed circuit boards.
