Americhem Inc., Cuyahoga Falls, Ohio, has launched a new line of highly concentrated, low-aniline, nigrosine black nylon masterbatches suited to automotive under-hood and other applications where retention of physical properties is important. They are also compatible with glass-filled nylon and can be combined with carbon blacks to achieve UV stability while maintaining physical properties.
Available in concentrations up to 40% in nylon 6 and 66, the nigrosine black masterbatches boast advantages over carbon black dispersions. Besides minimizing negative impact on physical properties, they provide a deep jet black, higher gloss, and minimal stress whitening compared with carbon blacks.
