Besides coloring, there are many other advantage of Additive Masterbatches. They result in increasing effectiveness against Fungi, Yeast, Algae and Bacteria. In addition, they also deliver more strength to plastic. Other properties are scratch resistance, strength enhancer, and brightener etc. The only thing one needs to take care of is to choose a reliable supplier of Masterbatches. A thorough research is much needed for this job and today internet opens up many possibilities for further research that would actually help in finding the best supplier.
