PTFE is most definitely an industrial material. It’s perhaps the toughest material that can be cut with a CO2 laser, offering great resilience against the oils, acids, heat and frictional processes that frequently occur in manufacturing and engineering processes.
Manufactured boards of PTFE, in thicknesses of up to 10mm, are available in very large sheet sizes, and are well priced alternatives to mild steel for prototyping, and easily machined with a laser. They are frequently used to produce very long lasting gaskets and electrical insulators.
We can cut and engrave PTFE up to 10mm. It cuts very cleanly, albeit slowly, leaving no sticky residue.
