Composition of Carbon Black MasterbatchIn accordance with international classification, China has more than 30
varieties. Mainly divided into rubber and non-rubber two categories. In
the rubber carbon black is mainly wear-resistant carbon black, can
effectively improve the wear resistance of rubber tires; in non-rubber
carbon black, only a few carbon black can really be used as black
masterbatch.
plastic color masterbatchThe carrier is a substance that carries carbon black. Generally, raw
material of the carrier and the final plastic product are the same. This
made the black masterbatch and plastic material blend better. For
example, for polyethylene plastic products, the carrier of black
masterbatch is polyethylene.
The specific gravity of Carbon black is about 2g / cm. Cause the carbon
black particle size is small, the performance density is small, seemed
fluffy and light. To smooth processing, carbon black has to be wet
first. Thi choice of wetting agent is critical. In order to reduce the
cost, a large number of companies using white oil or paraffin products,
which will seriously affect the strength of processed products.
Mainly divided into organic dispersant and inorganic dispersant two
categories. High-grade black masterbatch using organic dispersant,
mainly used for those products that needing higher environmental
requirements, such as drip irrigation products. Low-grade black
masterbatch using inorganic dispersant, commonly used calcium carbonate.
