Melting range determination of semi-crystalline polymers according to EN ISO 3146
Melting range determination of semi-crystalline polymers according to EN ISO 3146
According to the official regulation EN ISO 3146, [1] polymers do usually not have a sharp melting point as known for low-molecular substances. Here, we demonstrate the feasibility to employ the M-565 for the melting range determination of semi-crystalline polymers by capillary tube method according to EN ISO 3146 (method A). Semi-crystalline poly(tetrafluoroethylene) (PTFE) was chosen as test compound for the melting range measurements. For the analyzed PTFE samples we report a narrow melting range between 322.9 ± 0.4 °C and 326.0 ± 0.1 °C. With the M-565 the melting process can be measured and recorded without modification of the instrument.
