The refractive index is1.48-1.59,basically in line the PP,PE refractive index of 1.43-1.63 When the adding amount is 5-30%,the transparency is not affected,essentially the same with new material film(the thickness of the membrane is in 0.01mm-0.02mm).The masterbatch has small proportion,good heat sealing and tensile strength.The latest synthetic multiple blending transparent filler formula has basically eliminated the HDPE white stem phenomenon in blowing film.The product has a vast market and great application potential.High transparent filler masterbatch can be applied to thermoplastic polyolefin,such as PP,LDPE,HDPE,LLDPE,EVA,PVC,biodegradable plastics and recycled plastic,etc.For example,film tableware,plate,sheet,pipe,profiles,extrusion,injection molding,stretch film,etc.The product has good intermiscibility with these plastics.
