PE carrier defoaming masterbatch is a functional masterbatch based on polyethylene (PE) carrier, loaded with highly active moisture-absorbing components (mainly calcium oxide), dispersants and processing aids, compounded and pelletized under high shear. In PE injection molding, film blowing and extrusion, moisture in raw materials (especially recycled PE) causes bubbles, silver streaks, pinholes and surface defects, damaging appearance and mechanical strength. This masterbatch rapidly absorbs moisture during processing and converts it into inert substances. No pre-drying required—just mix and process, significantly improving yield and stability.
The key benefits of PE carrier defoaming masterbatch are remarkable: Effective moisture removal, which can completely eliminate bubbles, silver streaks, holes and surface blemishes caused by moisture, greatly reducing the scrap rate; excellent compatibility with PE, suitable for LDPE/LLDPE/HDPE and PE blends, without affecting transparency, gloss, toughness and tensile strength, and the transparent/food-grade grades have low haze and no migration; low dosage, the typical addition is 1%–3%, and the high-concentration grades can take effect at 0.5%–2%, with controllable cost; simplified process, eliminating drying equipment and procedures, mix-and-go processing, especially suitable for humid environments and recycled material production, significantly reducing energy consumption and labor costs; wide application, suitable for injection molding, film blowing, extrusion, recycled materials and other scenarios, and can be used for various PE products such as PE caps, food containers, packaging films, pipes, recycled pellets, etc.
Its typical specifications are for reference as follows: carrier is PE, active content is CaO (30%–70%, customizable), appearance is white/off-white pellets, addition ratio is 1%–3% (adjusted by moisture content), applicable temperature is 150–220℃, and the environmental protection grade can be selected as industrial grade or food contact grade. During use, the addition ratio can be adjusted according to the moisture content of the raw materials: 1.0%–2.0% for slightly moist virgin resin, 2.0%–3.0% for regular recycled PE, and 1.5%–2.5% for high-concentration grades in high moisture/humid environments. It can be directly mixed with PE resin uniformly and processed normally without drying.
