PET flame retardants

Transparent PET Film FR ER-F5100

ER-F5100(offered as masterbatch MB-PT110 with 10% ER-F5100) is a novel halogen-free flame retardant specifically developed for transparent PET films. With just a 1.5% addition, it can achieve UL94-VTM-0 at 0.050 mm thickness. Compared to traditional flame retardants for transparent PET films, the required FR dosage has been significantly reduced from 25% to 1.5%, greatly reducing costs. Additionally, ER-F5100 requires no special treatment prior to use. The applications of transparent FR PET films include: insulating tapes, printing, electronic products, etc.
