PTFE stands for polytetrafluoroethylene, a fluorocarbon-based polymer. The mechanical properties of PTFE are low compared to other plastics and can be used over a wide temperature range of -73 ° C to 204 ° C. Mechanical properties are usually enhanced by the addition of fillers. Filled PTFE generally retains its excellent chemical and thermal properties, while fillers improve mechanical strength, stability and abrasion resistance. It has excellent thermal and electrical insulation properties and low coefficient of friction.
Teflon is very dense and can not be processed by melting. PTFE tubing must be compressed and sintered to form a useful shape. PTFE is easy to process on all standard equipment, including state-of-the-art CNC machining equipment. Teflon can be cut, drilled, milled and turned using standard tools. Occasionally more stringent tolerances are required, but usually not necessary. PTFE is very flexible and allows the machining of parts to suit most working dimensions.
PTFE tubing easy to process, affordable, long service life. Parts made from this unique plastic are often used for mechanisms that rotate or slide due to the low coefficient of friction and abrasion resistance of PTFE. Like most plastics, parts do not require surface treatment and can stay in good condition for a long time. This unique plastic is non-tacky, moisture and chemical resistant, and has a high strength-to-weight ratio. It is easy to process, has excellent dielectric properties and high melting point.
