Partners seek to improve processing of glittery effects pigments.

Merck KGaA and the Indian materials engineering firm Steer are collaborating on a processing technology to enhance the use of special effects pigments, such as those based on mica particles, in plastics.

Steer’s twin rotating screw extrusion technology may eliminate this problem through the precise application of forces to the resin.
