PTFE (polytetrafluoroethylene) Fluorocarbon coatings are a coating that must be sintered at 725°F to form a thin film which makes it great for corrosion resistance, low friction and good release qualities. This thin coating works great for acid resistance, bear surfaces, and as a mold release for various resins.
PTFE is chemical inert to most chemicals and solvents except very strong alkali solutions. Most coating applications are 1 to 5 mils DFT. This coating can be used in applications as high as 550°F continuously and intermittently up to 600°F. With use temperature as low as minus 450°F, PTFE coatings work great in cyrogentic applications.
We have applied PTFE coatings on needles, rollers, chemical tanks, pipes, heat seals, molds and many other products. Some of DuPont's TEFLON®s, Whitford's XYLAN®s as well as other manufacturer's coatings contain PTFE for the above types of applications.
