PTFE, Poly-Tetra-Fluoro-Ethylene or Teflon® as is the most known trade name, is a tough plastic based material and is extremely temperature resistant with very low friction values.
The material is persistent against heated oils and petrol as well as a big set of acids and alkalis, which makes the PTFE well suited for products where multiple stresses will be put to the material.
We often see seals in PTFE in high demand products where temperatures and multiple chemicals will stress the material. Frequently seen products in various industries are PTFE is slide rails, gaskets, spacers, O-rings, tubes and turned products.
The material is FDA 177.1550 graded and is therefore suited in food industry, medical technology, and clean room products. Also frequently seen in automotive-, transportation,- electronics- and chemical technology industries.
A PTFE material may be acquired coal- and glass filled to bring forth other properties in the material. A carbon filled PTFE is a more mechanical and durable material. A glass filled PTFE contributes to a more compression resistant material and the material becomes less deformable under pressure. The material may also be reinforced with different fiber-inlays to, for example, decrease the materials elasticity. The material may be reinforced with glass,- aramide- and carbon fiber.
To laminate a PTFE may be problematic with the typical low friction and greasy surface the material is typical for. That is why we convert PTFE with an etched surface that is better suited for attaching double-sided adhesive and glue.
