Colourtone Masterbatch

Universal masterbatches are normally readily available from stock, in small quantities and are cost effective if used correctly. However, in terms of compatibility, they are a compromise and processing difficulties can arise with some materials and engineering polymers that may have to be pre-dried. They are not recommended for use at high dosage levels as the appearance or physical properties of the final product may be adversely affected.

Polymer specific masterbatch, which can be pre-dried with the host polymer, may be added at high loading without compatibility problems. However, there may be some limitations on the range of colours achievable and not all engineering polymers lend themselves to conversion to masterbatch.
