Choosing the right Masterbatch for different plastic products is a process that requires comprehensive consideration of many factors.
First, consider the type of resin of the plastic product. Because the carrier resin of Masterbatch needs to have good compatibility with the base resin of the plastic product. For example, for polyolefin plastic products, such as polyethylene (PE) and polypropylene (PP) products, it is best to choose Masterbatch with PE or PP as the carrier resin. If the compatibility is not good, Masterbatch cannot be well dispersed in the plastic matrix during processing, resulting in uneven color, surface spots and other defects. For example, when producing plastic chairs made of PP material, Masterbatch with PP carrier can ensure that the color is uniform and firmly attached to the surface of the chair.
Secondly, the application environment is also an important consideration. If the plastic product is used outdoors, such as outdoor trash cans, plastic decorative panels for building exterior walls, etc., it is necessary to choose Masterbatch with good weather resistance. These Masterbatches are added with special pigments and additives to maintain color stability in harsh environments such as long-term sun exposure, rain, and wind. For example, Masterbatch containing light-resistant and heat-resistant pigments can effectively prevent fading and discoloration in outdoor environments.
Coloring requirements should not be ignored either. For some plastic products that require high gloss, such as plastic toys and high-end plastic packaging, Masterbatch that can provide high gloss effects should be selected. The pigments and formulas of this Masterbatch can make the surface of plastic products smooth and shiny, improving the appearance quality of the product. For plastic products that require matte effects, such as some interior decoration parts with texture requirements, the corresponding matte Masterbatch should be used.
In addition, for plastic products with special functional requirements, it is also necessary to consider whether Masterbatch can meet these requirements. For example, in food packaging plastic products, Masterbatch that meets food hygiene standards and has good migration resistance should be selected to prevent the components in the Masterbatch from migrating into the food. In the plastic casing of electronic and electrical products, it may be necessary to select Masterbatch with anti-static properties to avoid static electricity from damaging electronic components.
