how do you distinguish between RPTFE and PTFE?
Update Time:2017-08-16
The colors are somewhat different, PTFE white, transparent, RTFE pink,.RPTFE enhanced, and more resistant to temperature.
RPTFE belongs to the enhanced processing of PTFE material, in the polymer structure and some additives content and PTFE difference.
We can make an infrared spectra of pure PTFE powder or film, and then the material or product scraping a flaking do the infrared spectral analysis, estimation of the infrared spectra of RPTFE have obvious difference spectrum and pure PTFE, should be more than PTFE. If some absorption region of compactness of the same or similar, these two kinds of material density also have the difference, the density of RPTFE may be a little higher.
Due to the addition of a certain amount of glass fiber during the manufacture of RPTFE, the infrared absorption of this part is different from that of pure PTFE.
R means Reinforced, which is used to enhance PTFE with Glass Fiber.
