What functions should the functional masterbatch have?

The functional masterbatch is a masterbatch containing a functional auxiliary component other than color. The specific function depends entirely on the active ingredients contained. These features can be easily divided into three main categories:

The first category: to improve the processing properties of plastic molding.

For example, processing aid masterbatch for reducing die fouling and eliminating melt fracture; cooling masterbatch for lowering molding processing temperature; dry masterbatch for absorbing moisture in raw material; smooth masterbatch for releasing molded parts; preventing film Anti-slip masterbatch that slips during winding; anti-blocking masterbatch to prevent adhesion between film and film when film is unwound; saves masterbatch for color change cleaning materials, etc.; It not only facilitates the operation of the forming process, but also improves the quality of the product, while also improving production efficiency and reducing energy consumption.

The second category: improving the physical and chemical properties of plastics.

For example, the anti-oxidation masterbatch for improving the heat aging property, suppressing the yellowing of the part; the anti-aging masterbatch for improving the weather resistance of the finished part; the nucleating masterbatch or the antireflective masterbatch for improving the rigidity or transparency of the molded part; Toughened masterbatch for mechanical properties; smooth masterbatch for reducing the surface friction coefficient of molded parts; open masterbatch for reducing the opening torque of caps; thermally conductive masterbatch for improving the thermal conductivity of plastic parts; conductive masterbatch for improving electrical conductivity, improved The mechanical properties of plastics and the cost of filling the masterbatch and so on.

The third category: increase product application functions.

Such as antistatic masterbatch to reduce the surface resistance of molded parts; flame retardant masterbatch to improve the fire resistance of materials; antibacterial masterbatch to increase the antimicrobial resistance of plastics; improve the barrier of penetration of gases (such as oxygen, carbon dioxide, water vapor) by plastic packaging materials Masterbatch; degradable masterbatch to reduce plastic pollution; deodorant masterbatch to remove odor; flavor-enhancing masterbatch to add flavor to plastic; anti-fog drop masterbatch to reduce fog on inner surface of food packaging film; prevent electronic components Rust anti-rust masterbatch; laser masterbatch that provides laser coding effect; matt masterbatch that provides matte effect or even matte effect, foaming masterbatch that provides weight loss, heat insulation, sound insulation and shock absorption;

The above are the three main functions of the functional masterbatch.
