Feature size, wall thickness, grade, stock condition, and measurement temperature determine whether it is practical. Critical dimensions and inspection conditions should be agreed before production.<\/p><\/div><\/details><details><summary>Which PTFE grade should I choose?<\/summary><div class=\"pt-answer\"><p>Virgin PTFE is often considered for chemical resistance and electrical insulation. Filled or modified grades may suit loaded, sliding, or sealing duties, but their exact chemical, wear, and electrical properties must be checked against supplier data.<\/p><\/div><\/details><details><summary>Can PTFE parts be bonded, printed, or coated?<\/summary><div class=\"pt-answer\"><p>PTFE has very low surface energy. Adhesion normally needs qualified preparation, such as chemical etching or a specialist plasma process, followed by testing with the actual adhesive, ink, or coating.<\/p><\/div><\/details><details><summary>Can PTFE be used at 260\u00b0C?<\/summary><div class=\"pt-answer\"><p>Some grades are rated for service up to about 260\u00b0C under specified conditions.
