PTFE Properties andRod, Tubing

PTFE ( PTFE Rod, PTFE Tubing) is many plastic material is one of the most stable heat of a kind of plastic, In **0cases not happen metamorphism. Therefore, in this case, PTFE still keep it most of the properties. In **0 its performance began to appear the phenomenon of depreciation. so, in the fluorocarbon & plastic, PTFE (PTFE Rod, PTFE Tubing) Won the reputation of plastic king. PTFE (PTFE Sheet, PTFE Rod, PTFE Tubing) is a thermoplastic polymer, which is a white solid at room temperature, with a density of about 2.3 g/cm3 . Its mechanical properties degrade gradually at temperatures above −*9 (−**0 ). PTFE (PTFE Sheet, PTFE Rod, PTFE Tubing) gains its properties from the aggregate effect of carbon-fluorine bonds, as do all fluorocarbons. PTFE is a thermoplastic polymer, which is a white solid at room temperature, with a density of about ***0 kg/m3. According to DuPont, its melting point is **0 K (**7 ; **0 ). Its mechanical properties degrade gradually at temperatures above **4 K (−*9 ; −**0 ). PTFE (PTFE Sheet, PTFE Rod, PTFE Tubing) gains its properties from the aggregate effect of carbon-fluorine bonds, as do all fluorocarbons. The only chemicals known to affect these carbon-fluorine bonds are certain alkali metals and most highly reactive fluorinating agents. The coefficient of friction of plastics is usually measured against polished steel. PTFE (PTFE Sheet, PTFE Rod, PTFE Tubing) coefficient of friction is 0.*5 to 0.*0, which is the third-lowest of any known solid material (BAM being the first, with a coefficient of friction of 0.*2; diamond-like carbon being second-lowest at 0.*5). PTFE (PTFE Sheet, PTFE Rod, PTFE Tubing) resistance to van der Waals forces means that it is the only known surface to which a gecko cannot stick. PTFE has excellent dielectric properties. This is especially true at high radio frequencies, making it suitable for use as an insulator in cables and connector assemblies and as a material for printed circuit boards used at microwave frequencies. Combined with its high melting temperature, this makes it the material of choice as a high-performance substitute for the weaker and lower melting point polyethylene that is commonly used in low-cost applications. Because of its chemical inertness, PTFE (PTFE Sheet, PTFE Rod, PTFE Tubing) cannot be cross-linked like an elastomer. Therefore, it has no "memory" and is subject to creep. This is advantageous when used as a seal, because the material creeps a small amount to conform to the mating surface. However, to keep the seal from creeping too much, fillers are used, which can also improve wear resistance and reduce friction. Sometimes, metal springs apply continuous force to PTFE seals to give good contact, while permitting a beneficially low percentage of creep.
