Masterbatch is liquid of solid additive for plastic that is used for coloring or imparting different properties to plastic. It is a concentrated mixture of additives and pigments that are encapsulated in the heat process to carrier resin that is then cooled and then cut into granular shapes. Processors use masterbatch to economically color raw polymer in the plastic manufacturing process.
Masterbatch is preferred by many because it is less expensive compared to buying a material that is fully compounded. Such a material is not only expensive, but can also be less open to product color variability. The concentrates are also preferred over compounding raw materials on site because they do not have dispersion issues of additives and colorants as it is the case with the compounding process. They might require longer lead times and more storage space, but masterbatches are still advantageous in more ways than one. They offer excellent coverage power and dispersion so they are able to meet requirements for various end user applications and resins. Below are some of the benefits black masterbatch offers to final products.
· Excellent mechanical properties offering better tear and impact resistance and balance stiffness
· Excellent dyeing power
· Enhances appropriate stretching
· Suitable and compliant even for food packaging
· When combined with latest additives, black masterbatch offers thermal stability, UV radiation protection, electrical conductivity, bactericidal effects and flame propagation resistance, heat dissipation and thermal conductivity
These benefits are what makes black masterbatch excellent solution for different segments. Some of the segments that benefit and use the black concentrates include:
· Agriculture for irrigation pipes, agricultural tarpaulins and mulching purposes
· Automotive for technical parts production through polymer engineering
· Electric for electronics such as mixers, blenders, washing machines, coffee machines, vacuum cleaners, TVs and DVDs among many other items
· Packaging for blowing film, flatting film, coatings, injecting and blowing sheets and direct contact with fatty foods and dairy products
· Shoes for the production of blankets and EVA soles
· Raffia for the production of sacks meant for wheat flour, sugar, animal feed and raffia as well as other plasticulture applications
· Fibers to get multifilament and monofilaments
· Construction for wires, cables, geomembranes, hoses, plugs, profiles and fittings, corrugated tubes and water tanks
There are so many masterbatch manufacturers today and you would need to choose a reliable one to have a good experience purchasing and using the concentrates that you needs. Some of the questions that you should ask before placing your order are;
· What will I use the masterbatch for?
· Is it going to get in touch with potable water?
· Is FDA approval necessary?
· What directives need to be adhered to?
· Is it necessary that it is free from heavy metals?
· Does it need additives to enhance performance?
· Is it for outdoor or indoor use?
