2013年8月1日 · Dynamic mechanical and tensile tests show that PTFE’s Tg is located at ca. −103 °C. Polytetrafluoroethylene (PTFE) has been used for many years in different application fields due to its outstanding chemical and physical properties.
Polytetrafluoroethylene - Wikipedia
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] . The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4]

PolytetraflonTM- PTFE - ElringKlinger Engineered Plastics
Polytetraflon TM PTFE (polytetrafluoroethylene) is the name given to a straight-chain, linear, semi-crystalline polymer consisting of fluorine and carbon. PTFE, modified PTFE, and the PTFE compounds produced from it have an array of impressive properties that provide the ideal solution to certain technical problems.
Properties of Polytetrafluoroethylene (PTFE) - Matmake
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. It is a high-performance plastic known for its non-stick properties and resistance to chemical and thermal conditions. PTFE is commonly recognized by the brand name Teflon, which is often used for non-stick coatings in cookware.
PTFE: Polytetrafluoroethylene - NETZSCH Polymers - Group
The DSC curve of the PTFE sample exhibits two overlapping peaks around 20°C. The peaks were sharper in the 2nd heating (green) than they were in the 1st heating (blue) with peak temperatures of 23°C and 32°C.
