IV Modifier Masterbatch offered by us is designed and manufactured by making use of premium-grade raw materials and the latest technology. During extrusion, increases the intrinsic viscosity of PET scrap material. When PET scrap material is employed in the manufacture of PET straps, the strength of the straps decreases, and strap splitting occurs. IV Modifier Masterbatch helps to increase the mechanical qualities of the product. This is also used to improve melt strength by increasing molecular weight. This is very effective and economical and safe to use.
