Product Function


PP/AS/ABS Injection Molding

PP/AS/ABS injection molding masterbatch is used in plastic processing to improve the coloring and properties of plastics.

Type and Characteristics


  • PP injection molding masterbatch: PP (polypropylene) injection molding masterbatch has good weather resistance, heat resistance, and chemical stability, and is suitable for fields such as household goods, automotive industry, packaging industry, etc.

    AS injection molding masterbatch: AS (acrylonitrile styrene copolymer) injection molding masterbatch has high transparency and glossiness, and is commonly used to make transparent or semi transparent plastic products.

    ABS injection molding masterbatch: ABS (acrylonitrile butadiene styrene copolymer) injection molding masterbatch has excellent comprehensive performance and good impact resistance, and is widely used in home appliances, electronic products and other fields


Function and Application

  • Coloring function: By adding color masterbatch, plastic products can have various colors to meet different appearance requirements.

    Enhanced performance: Some masterbatch can enhance the mechanical properties, heat resistance, weather resistance, etc. of plastics, such as PP injection molded flame retardant masterbatch can improve the flame retardant performance of plastic products.

    Improving processing performance: Some masterbatch can improve the processing performance of plastics, such as PPA masterbatch, which can reduce the adhesion of plastic films and improve production efficiency.

Common Problems and Solutions

  • Dispersion issue: Uneven dispersion of masterbatch in plastic can cause problems such as color spots on the surface of the product. The solution includes selecting appropriate dispersants, controlling the particle size and dosage of masterbatch, etc.

    Heat resistance issue: During high-temperature processing, the coloring agent in the masterbatch may decompose, affecting the color and quality of the product. Colorants with high heat resistance should be selected.

    Migration issue: Some pigments may migrate out of plastic products, causing color pollution or other problems. The use of pigment products with potential migration should be avoided based on the actual application needs of the product.


Safety and Environmental Protection

  • Injection molding masterbatch should comply with relevant safety standards and environmental requirements, such as RoHS directive, to ensure that the product is harmless to human health and the environment during use.

In summary, PP/AS/ABS injection molding masterbatch plays an important role in plastic processing, which can improve the properties, appearance, and processing performance of plastics and meet the needs of different fields.
