Masterbatch 0.1~3mm granular solid made up of particle size. 0.1mm (100 µ m) particles of powder 1~10 µ m as a fine powder 0.1~1 µ m for powders; 3mm particles of broken solid blocks. Size is smaller, more compact the mixture. Smaller but the same solid particle size, particle easier absorption between Pellet, the Pellet, and the other a mixture of solid particles, it is not easy to open, also difficult to disperse in the plastic melts.
