Masterbatches By Saraswathi Plastic Industries

In order to modify the appearance and improve the performance properties of polymers, such as LDPE, EVA, PP, PET, etc, various kinds of additives are incorporated into the plastic during the melt extrusion process. However, additives come in all forms, such as powders, liquids, granules. Also, polymers may be in power, flake or pellet forms. Therefore, it is very difficult to add and disperse the various forms of additives accurately to make a uniform plastic formulation.
A master batch, which is a concentrated uniform dispersion of the additives in the form of a plastic pellet, is used to achieve the proper concentration and dispersion of the additives. The master batch is prepared by dry blending, melt mixing and pelletization processes using the appropriate commercially available plastic compounding equipments. The additive master batch is prepared in a carrier resin compatible with the final plastic product.

This material is available in the following grades:
(1) Low Cost Black Master batch-PE Based
(2) Tailor Made Fillers and Master batch As Per The Customers Requirement
