PIB (Poly ISO Butylene) Description : PT-60-PIB is an average molecular Poly Isobutylene based masterbatch based on polyolefins. It contains the blend of Poly-Iso-Butylene & Special additive dispersed in the polymer matrix, made in the state of the art plant to give excellent performance in extreme climatic conditions. PIB Masterbatch is mainly used in LLDPE / LDPE self adhesive Stretch Film, Cling Film, & Wrap Film (either Blown Film or Cast Film) and it is available in granule form. PIB master batch is available in the granule form which is very easy to handle as against the direct dosing of PIBliquid which is very difficult & tedious to handle due to high viscosity. Our PIBmaster batch distributes very uniformly over the entire film imparting the strength & tackiness properties to the film with self adhesive properties. And this property of the film helps to bind the packages together with proper grip. In multi-layer films, PIB master batch, is used only in one layer, that is the upper layer and the adding ratio is determined by the film thickness and on the layer to be used. Specifications : Appearance : Natural translucent pellet Active ingredient : 60 % (+ / -1%) Compatibility : LDPE , LLDPE, PP, EVAetc. Addition Levels : Cling films made from our PIB master batch are most economical and the quality of the film coverage increases on stretching. The loading of PIBmaster batch varies from 3% to 8% depending upon the type of the film plant (Blown or Cast Line) installed. We suggest the following addition level based on the test results from outdoor weathering tests and from practical experience: Blown Film Application : 6 to 8 % Cast Film Application : 3 to 4 % The above dosages are for guidance only. Actual condition may vary from film to film, process to process and also upon the thickness of the film and its specific uses.
