Mar 06, 2013 · Teflon molecules do not cross-link. Cross-links tie molecules together. Without these cross-links Teflon molecules are free to move around. Under stress, Teflon will creep. The high coefficient of expansion and stress creep properties often makes the goal of tight machining tolerances a futile exercise.

Abstract. Further results on the frictional properties of Teflon-steel interfaces in sliding bearings are reported. Values of the breakaway (static) and sliding coefficients of friction of woven Teflon in contact with polished stainless steel for sliding velocities of up to 10 in./sec (254 mm/s) and bearing pressure of 6,500 and 10,000 psi (44.9 and 69 MPa) are reported. Reduce friction and provide long-lasting lubrication with the dry lube PTFE spray from WD-40. This formula dries quickly and resists dirt and dust. WD-40 Dry Lube Spray is great for door and window tracks, slides, belts, rollers and hinges.
Teflon™ mechanical properties are low compared to other plastics, but its properties remain at a useful level over a wide temperature range of of -100°F to +400°F (-73°C to 204°C). Mechanical properties are often enhanced by adding fillers (see paragraph below). It has excellent thermal and electrical insulation properties and a low coefficient of friction.…

PTFE FDA / WRAS: WHITE-250⁰C to +250⁰C – A Virgin PTFE free flow granular resin used in a multi-purpose role with an excellent combination of handleability, processability, machinability and end use properties. Meets the FDA regulation under code 21CFR 177.1550 and EU Directive 10/20
Unlike PTFE/Teflon-type non stick coatings that require high heat assistance for curing, Wearlon is room temperature cure industrial non-stick coating. No heat is required. Now, a tough non stick can be applied any time, anywhere. Wearlon is a water based, low VOC, environmentally friendly, silicone-epoxy coating.
When a dielectric is placed between charged plates, the polarization of the medium produces an electric field opposing the field of the charges on the plate. The dielectric constant k is defined to reflect the amount of reduction of effective electric field as shown below.

Its properties also make it useful as a component in the production of Gore-Tex. PTFE (Teflon) is hydrophobic, meaning it easily repels and shreds water AND it is also oleophobic and shreds oil in the same way it repels water. Both types of these liquids has difficulty in adhering to a PTFE surface.
Dec 03, 2012 · It is cheaper than PLA and it also can be recycled, but contrary to PLA, it is made out of oil (the production of 1 Kg of ABS requires about 2 Kg of oil, see the wikipedia ). Obviously it also comes in many colors, including transparent as PLA (but can be made even with some acetone finish, see below).
