A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%). B Calculated values *Derived data by calculation.
PCTFE is also used for laminating other polymers like PVC, polypropylene, PETG, APET etc. It is also used in tubes, valves, chemical tank liners, O-rings, seals and gaskets. [15] PCTFE is used to protect sensitive electronic components because of its excellent electrical resistance and water repulsion.
Melting point 195–265 °C (383–509 °F; 468–538 K) [ 1 ] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
The melting point for average commercial low-density polyethylene is typically 105 to 115 °C (221 to 239 °F). These temperatures vary strongly with the type of polyethylene, but the theoretical upper limit of melting of polyethylene is reported to be 144 to 146 °C (291 to 295 °F). Combustion typically occurs above 349 °C (660 °F).
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.

[3] [4] Furthermore, other molecules in the polymer solution, such as salts or proteins, can alter the cloud point temperature. [ 5 ] [ 6 ] Since PNIPA expels its liquid contents at a temperature near that of the human body , PNIPA copolymers have been investigated by many researchers for possible applications in tissue engineering [ 7 ] [ 8 ...
