Technical facts about color masterbatches
Since their introduction in the 1960s the color masterbatches has steadily penetrated the traditional colored compound market. It is a solid concentrate of color and/or performance enhancing additives such as anti-static, UV stabiliser, metal deactivator, etc., that is added to a base polymer to impart these attributes. It is usually supplied in granular form, either as pellets similar in size to most polymers or as miniature pellets, known as micro granules. Alternatively, they can be delivered in 'rough cut' form - a mixture of small shreds and chunks. Two main types are offered - polymer specific and universal. Polymer specific masterbatch is produced using the same base polymer group. Universal they 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. Universal ones are normally readily ...
