Off-white Desiccant Masterbatch
Desiccant masterbatch also named defoaming masterbatch/moisture absorber, as the new functional masterbatch removing moisture generated during the production processing when we use the recycled PE/PP materials. We simply mix it with raw materials before starting production process without drying process, which can reduce production cost and save labor. To solve all the surface problems of bubbles, moire, and cracks caused by moisture, which can improve the production efficiency and reduce energy consumption.
Product Description
Comprising PE wax and paraffin wax to improve dispersion, the defoamer masterbatch is effective in eliminating moisture (absorbing 20%), moire, and air bubbles in recycled resin. With a CaO content of 70%-80%, it is offered in three colors—white, grey, and black—achievable through the addition of pigment powder. The price hierarchy for the defoamer masterbatch is: White > Grey > Black.
