(PresseBox) - Pinneberg/Germany, August 7th, 2014 ? ROWA Masterbatch, the specialist for polymer specific colour, additive and multifunctional masterbatches, proves expertise: the Pinneberg-sited company is one of the few manufacturers who has been producing a high quality PA nigrosine masterbatch for many years. This colour masterbatch is particularly suitable for black colouration of glass-fibre-reinforced nylon grades used in automotive engine parts. As the manufacturer of the PA nigrosine masterbatch, the company is not only a supplier of the automotive industry, it also supplies a number of established nylon manufacturers and compounders.
Carbon black is the traditional colourant ? also in the automotive industry. However, carbon black can interfere with the mechanical properties and material behaviour during injection moulding. Therefore, soluble colourants are preferred for applications ?under the hood?. This includes nigrosine: these complex dyes are incorporated into a polymer matrix where they can dissolve. The colourant, with the Color Index Solvent Black 7, readily dissolves and thus provides a number of advantages compared to carbon black, particularly for glass-fibre-reinforced nylon: the surfaces of the parts have a high gloss level while the mechanical properties, such as the impact resistance, remain unchanged. Furthermore, nigrosine promotes complete filling of the mould because it does not increase the melting temperature of the polymer.
ROWA Masterbatch also attaches great importance to the subject of environmental protection: The company only uses state of the art low emission nigrosine grades. Needless to say, that the extensive product portfolio of the Pinneberg-based manufacturer also includes a large selection of recipes containing conventional carbon black grades.
