Light stabilizing additives, especially highly effective ones, are likely to suffer from uneven distribution during the blending process. A common practice is to pre-blend the additives into master batches (MB), a type of target material granules with relatively higher concentration of the featured additive, or additive combinations. Apart from more even distribution, the adoption of master batches greatly reduces dust formation which causes waste and worse, pollution.

Our master batches are widely used in functional film, artificial turf, plastic woven bags etc.

General Composition

Generally, light stabilizing master batches are designed to be resistant against UV. Therefore the majority combine at least antioxidants and light stabilizers. Most antioxidants and most light stabilizers are suitable for preparing master batches.
