Temp decomposition of pvc
Web20 Dec 2015 · Flexible PVC film starts to soften at 60C/140F. This is due to its plasticizer content. The softer the film, the more plasticizer, the lower temp it melts at. So if your film will only be exposed to a heat environment below 60C/140F, flexible PVC film is a good choice. If you need a great film that will resist more heat than that, virtually all ... WebAfter exposure to temperatures up to 600 °C, the properties of geopolymer mortar containing BLWA reduced more than that of the control mortar due to the thermal degradation of BLWA at high temperatures. ...
