Masterbatch-Explained By The Experts
Posted by sungbocoltds on August 30th, 2013
The industrial processes involve several components and each component has its own use. The production of plastics is one such process where several minute components are used. One such component is-Masterbatch, which is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape. Masterbatch allows the processor to colour raw polymer economically during the plastics manufacturing process.
How is masterbatch produced? Masterbatch manufacture is a two step process-gathering ingredients and then mixing them together by applying heat and shear to produce a homogenised pellet. Even distribution (dispersion) and development (breaking down) of the additives throughout the carrier are essential. This processing depends on several key elements: formulation, quality of raw materials, and quality of mixing and compounding plant. Finally you get masterbatch in many colours e.g. - white masterbatch, black masterbatch, coloured masterbatch etc.
Difference between masterbatch and pre-coloured resin A masterbatch is pre-dispersed concentrated color that is let down with natural polymer during moulding. With a precolor the entire polymer is compounded with the proper amount of color and delivered ready-to-use, eliminating metering and dispersion difficulties. A masterbatch offers economic advantages associated with resin purchasing and color obsolescence. Additionally, since masterbatches are not fully compounded most of the polymer used does not exhibit an additional heat history, potentially deteriorating the properties of some polymers.
Types of Masterbatch Polymer specific: Polymer specific masterbatch is produced using the same base polymer group as the type being used by the processor. Universal: Universal masterbatch employs a carrier system that is capable of carrying the high quantities of additives necessary to deliver the end use properties required as well as affording the essential compatibility required across a broad range of polymers.
For what kind of polymers masterbatch are used? For almost every known polymer! It is better to use resin specific masterbatches for engineering plastics in order to be able to retain the physical properties. Uses of masterbatch Masterbatch is used in the production of a variety of polymers. Injection moulding, blow moulding, profile extrusion, sheet extrusion, film extrusion, cast film, fibres and calendered sheet processes commonly employ masterbatch.
Where to get good quality masterbatch from? There are many different masterbatch manufacturers to choose from, so you should be able to find one that offers quality and service to match your exact requirements. Sungbo is one such company that is the leading manufacturer and supplier of high quality, filler white masterbatch (Calcium Carbonate concentrate) in South Korea. The masterbatch solutions provided by the company help you to create cost-effective packaging, consumer products and industrial goods, as well as enable to make injection, extrusion and other processes more efficient.
