May 1, 2017 · TG and DSC curve of PTFE fibers are depicted in Figure 4. The melting point (T m ), crystallization temperature (T c ) and the decomposition temperature (T d ) were noted on the DSC and TG curves. The T d was defined as the point at which the mass loss was 5%.

Polytetrafluoroethylene (PTFE)-based matrix composites filled with glass fibers (GF) and graphite (GR) were prepared by an internal mixer and molded using a compression mold to produce test...

Figures 3 to 5 display the resulting curves of the DSC, DMA and rotational rheometer measurements. The DMA measurement (figure 3) shows that the elastic modulus of the polymer amounts to almost 6500 MPa at -160°C. It decreases by more than half of its initial value during heating to -100°C.

In the following, a PTFE sample was measured with DSC, DMA and rotational rheometry. These three methods go hand in hand: DSC provides information about the ther - mal properties of a material, DMA and rheometry offer the possibility to obtain (among others) the viscoelastic properties of the sample by evaluating the response to

Structure and properties of polytetrafluoroethylene (PTFE) fibers were characterized thoroughly by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy,...

DSC analysis of PTFE specimens (heating rate: 10 ° C/min). In this work, the effects of crystallinity on the LPV (short for the limiting PV) value and tribological behaviors were investigated...

Apr 10, 2020 · DSC experiments are performed to study the crystallization kinetics of PTFE. A heat flux DSC apparatus Q10 from TA instruments was used for the different calorimetric measurements. Nascent PTFE samples were first melted at 375 °C for 300 s and then cooled down at various cooling rates.

One of the tools proven to address these needs is differential scanning calorimetry (DSC). This tool features many powerful techniques for studying polymer thermal properties and provides essential information to the polymer industry and end users of polymer-based products.

The deformation mechanism and phase transition behavior of polytetrafluoroethylene (PTFE) under stretching conditions (25, 50, 100 °C) were investigated by using differential scanning calorimetry (DSC), small angle X-ray scattering (SAXS), and X-ray diffraction (XRD).

... temperature associated with the thermal stability of the investigated PTFE is evidenced by the TG curves and DrTG (derived from TG) and occurs until reaching around 453ºC, as shown in Figure...
