摘要: Abstract Promising effects of DOPO-PEPA (DP), an environmental-friendly flame retardant, on the processing polyethylene terephthalate (PET) are studied via rheological experiments. DP reveals profound melt stabilization and lubrication even at low concentrations (~1 wt%). Mechanical characterization PET films confirms that direct addition powder to during extrusion has no adverse if exposed elevated temperatures for prolonged periods. This property is particularly interesting high-temperature applications, instance flexible power electronics, where mechanical flexibility should not be compromised by using a process stabilizer.
