Expanded Polytetrafluoroethylene - an overview ...

Table 5.12 summarizes the values of melting peak temperatures. There are two melting peaks, labeled 1 and 2. The high melting point of ePTFE crystal, around 380°C, seems to be related to the level of molecular chain orientation. The powder, raw tape (calendared sample), and uniaxial 5X drawn sample do not share this high melting point.

Polytetrafluoroethylene - an overview | ScienceDirect …

Polytetrafluoroethylene is a highly crystalline robust unique plastic with a high melting point. The material has a propensity to exhibit considerable elastic deformation under load. Consequently, in applications that require a frictionless surface and resistance to load, such as bearing surfaces, the deformation characteristics of PTFE are improved with the use of additives and fillers.

PTFE vs Teflon - Is there any real difference between …

2018-8-8 · PTFE is a synthetic polymer compound. It is a solid made of carbon and fluorine. Free radicals polymerize with tetrafluoroethylene to create the amazing substance, Polytetrafluoro Ethylene. The high melting point of PTFE makes it difficult to produce. Even when melting occurs, the consistency of the polymer is closer to gel than it is to water.
