PTFE Properties
 

PTFE's high PTFE Lined valve makes it ideal for laboratory environments as containers, magnetic stirrer coatings, and as tubing for highly corrosive chemicals such as hydrofluoric acid, which will dissolve glass containers.PTFE is also widely used as a thread seal tape in plumbing applications, largely replacing paste thread dope.PTFE grafts can be used to bypass stenotic arteries in peripheral vascular disease, if a suitable autologous vein graft is not available.PTFE can be used to prevent insects climbing up surfaces painted with the material. PTFE is so slippery that insects cannot get a grip and tend to fall off. For example PTFE is used to prevent ants climbing out of formicaria.
