Pinneberg/Germany, August 19th, 2021 – The ROWALID® EcoPA-B095A BLACK rCB masterbatch is a new product in this series. Its carrier material is based on high-quality post-industrial recycled polyamide. The colorant used is a recovered carbon black (rCB). A "green" substitute for industrial carbon black, this raw material gives plastics a black coloration, UV protection and opacity.
Recovered carbon black is obtained through the pyrolysis process: this is a thermal process in which used tires are heated up to between 250 and 750° C without the presence of oxygen and subsequently broken down into smaller molecules. This process typically produces a highly aromatic pyrolysis oil (approx. 45%), crude pyrolysis carbon black (approx. 33%), recycled steel (approx. 12%), and a non-condensable hydrocarbon gas (approx. 10%). By grinding and granulation, the crude pyrolysis carbon black can then be processed to recovered carbon black and further treated as required .
The new black masterbatch is ideally suited for applications in automotive engineering, electronics and electrical engineering, construction, and sports and leisure products.
