The colorant is in the form of concentrate pellets added to the polymer pellets during the extrusion and melting process. This is where dope-dyeing and Avient’s colorant technology, along with Coloro’s colors, can help. Coloro is the future of color.

But beware: Matching colors on disparate materials, such as textiles and molded polymers, is not an easy task. In recent years, Tier suppliers have proposed designs featuring colored textiles in locations typically filled with hard polymer surfaces. Certainly though, automotive interior designers will need to stay abreast of advances in colorant technology for textiles and polymers to help them add the most sensory impact to a vehicle.
