A filler masterbatch, also known as a filler compound or filler additive, is a specialized additive used in plastic manufacturing processes to enhance the properties and reduce the cost of plastic products. It is composed of a carrier resin and a high percentage of inorganic fillers, such as calcium carbonate, talc, or other minerals.

Fillers used in filler masterbatch are typically inorganic materials, chosen for their specific properties and cost-effectiveness. Common fillers include calcium carbonate, talc, kaolin, glass fibers, and more. The selection of fillers depends on the desired properties, such as improved stiffness, dimensional stability, impact resistance, or cost reduction.
The carrier resin used in the filler masterbatch should be compatible with the base resin of the plastic product. Common carrier resins include polyethylene (PE), polypropylene (PP), polystyrene (PS), and others. Compatibility ensures proper dispersion of the fillers and avoids any compatibility issues with the base resin.
Effective dispersion of the fillers within the carrier resin is essential for uniform distribution and optimal performance. Techniques such as melt mixing, extrusion, or compounding are employed to ensure proper dispersion and prevent agglomeration of the fillers.
The loading level of fillers in the masterbatch can vary depending on the desired properties and cost considerations. Higher filler loading levels can lead to greater cost reduction but may impact certain properties of the plastic, such as impact strength or transparency.
Filler masterbatch is used to improve various mechanical properties of the plastic, such as stiffness, dimensional stability, and impact resistance. The addition of fillers can increase the rigidity of the plastic, reduce shrinkage, and improve resistance to stress and deformation.
Filler masterbatch is widely used to reduce the cost of plastic products by replacing a portion of the expensive base resin with more economical fillers. By utilizing fillers, manufacturers can achieve cost savings while maintaining acceptable performance levels.
Filler masterbatch finds applications in a wide range of industries, including automotive, construction, packaging, and consumer goods. It can be used in various plastic manufacturing processes, such as extrusion, injection molding, blow molding, and others.
While filler masterbatch offers several advantages, it is important to consider its potential impact on other properties of the plastic. Depending on the specific filler and loading level, there may be some trade-offs in properties such as transparency, tensile strength, or processability. It is essential to perform compatibility testing and evaluate the overall performance of the plastic product.
