Structural properties between two types of PTFE subjected to heat treatment.

Abstract

Abstract
In this study two type of pure polytetrafluoroethylene (PTFE) (C2F4). China_UAE source prepared from solution cast as film and strip have been studied by structural properties (X-ray diffraction (XRD) and Differential Scanning Calorimetry (DSC).subjected to different temperature heating cycle. Both modifications show variation in the scattered X-ray intensity of the basal plane (100) as the temperature of heating cycle is changed .Moreover, the Enthalpy of each kinds is changed with difference of heat treatment .It seems that the product company of china is better than the product company of UAE in degree of crystallinity for this polymer .
Keywords: PTFE, degree of crystallinity, DSC
