Black masterbatch is a cornerstone in the plastics industry, providing essential colour and functional properties to a wide range of plastic products. Despite the evolution of new technologies and materials, black masterbatch remains highly popular due to its versatility, cost-effectiveness, and unique properties. This blog will explore what black masterbatch is, its brief history, why it remains popular, and its various applications.
What is Black Masterbatch?
Black masterbatch is a concentrated mixture of carbon black, carrier resin, and various additives that are used to impart colour and enhance the properties of plastic products. It is widely used in the plastics industry to colour plastic resins and improve their mechanical, electrical, and UV-resistant properties.
A Brief History of Black Masterbatch
The history of black masterbatch dates back to the early 20th century when the use of synthetic polymers began to revolutionise manufacturing. Initially, black pigments like carbon black were directly mixed with polymers to achieve the desired colour. However, this method had limitations, including inconsistent colour dispersion and difficulties in handling and processing.
The development of masterbatch technology provided a solution. By pre-dispersing pigments in a carrier resin, manufacturers could achieve more consistent and high-quality colour distribution. This innovation not only improved the aesthetic quality of plastic products but also enhanced their performance characteristics.
Why is Black Masterbatch Still Popular?
