PTFE, poly-tetra-fluoro-ethylene, or Teflon®—its best-known brand name—is a durable plastic-based material that is extremely heat-resistant and has very low friction coefficients.
The material is resistant to hot oils and gasoline, as well as a wide range of acids and alkalis, making PTFE suitable for products where the material is subjected to a variety of stresses.
Customizable materialFor products with high standards
We often see PTFE seals in high-performance products where the material is subjected to high temperatures and exposure to multiple chemicals. PTFE is commonly found in products such as slide rails, gaskets, washers, O-rings, tubes, and turned parts across a wide range of industries.
The material is FDA 177.1550-certified and is therefore suitable for use in the food industry, medical devices, and cleanroom products. The material is commonly used in the automotive, transportation, electronics, and chemical engineering industries.
PTFE can be filled with either carbon or glass to impart different properties to the material. Carbon-filled PTFE is a material with greater mechanical strength and wear resistance. Glass-filled PTFE provides better compression resistance and reduced deformation under pressure.
The material can also be reinforced with various types of fiber reinforcements to, for example, reduce its elasticity. The material can be reinforced with glass, aramid, and carbon fiber reinforcements.
Laminating PTFE can be problematic due to the low friction and greasy surface that are typical of this material. For this reason, we also process PTFE with an etched surface, which is better suited for bonding with double-sided adhesives and glues.
