Gray Defoaming Functional Masterbatch Product Code: PE-300– Non-Toxic and Eco-Friendly
This defoaming masterbatch is an innovative functional additive specifically engineered to address persistent moisture-related foaming issues during the processing of PS (polystyrene) products. Formulated using nanotechnology, it incorporates inorganic nano-powders and moisture-absorbing agents into an organic polymer base, resulting in a uniformly dispersed organic-inorganic nanocomposite masterbatch.
When blended into the plastic matrix, it effectively captures and eliminates moisture throughout the molding process. It exhibits excellent compatibility with polyethylene (PE) and polypropylene (PP) resins. Suitable for use with both virgin and recycled materials—including moisture-affected plastics—this product helps enhance product quality, increase production yield, improve processing efficiency, and reduce energy consumption. It is non-toxic, non-irritating, and environmentally safe.
Applications
Ideal for a variety of polyethylene (PE) and polypropylene (PP) molding processes, including blow molding and injection molding.
