Plastic desiccant masterbatch is a new functional masterbatch developed to eliminate moisture of recycled polyethylene and recycled polypropylene. The recycled polyethylene (PE) or recycled polypropylene (PP) usually contains a certain amount of moisture. If the moisture is not removed during the processing of the product, there will be bubbles or watermarks and even holes on the surface of the product, which will affect the beauty and performance of the product, even causes the processing failure, the product is scrapped. Adding a small amount of Desiccant masterbatch with the material can absorb moisture Before plastic molding, All the process of production without drying, and can be directly molded. Desiccant masterbatch is an environmentally friendly, energy-saving, convenient use of a new functional masterbatch.

Our company desiccant masterbatch is divided into general-type and special type. General type Desiccant color is gray-white, all kinds of PE or PP plastic products can be applied. The special type is a black pellet, contains antioxidants, that is specially developed for anti-oxidation requirements of plastic products and functional masterbatch. Such as cables, black pipes, and other black plastic products.
