CLEVELAND – 2017年10月31日 – PolyOne today launched OnColor™ Brilliant Metallic Colorants, a striking new line of special effect masterbatches that finally meet the need for paint replacement and premium surface finish. Our customers across multiple industries have been looking for a paint-free solution with no tradeoffs, which drove us to develop this new masterbatch.

Using a specific masterbatch enables proper charging. Together with the fiber denier, gram weight, and number of layers, this masterbatch ensures the middle layer of the filter can effectively trap smaller particles.

This allows our customers the choice of a masterbatch concentrate or pre-colored material that best fits their production process, yet still offers the benefits of our ‘Controlled, Consistent, Compliant’ customized solutions.”  NOTE: On 2020年7月1日, PolyOne and Clariant Masterbatches joined together as Avient, a new kind of materials company focused on conquering customer challenges and unlocking the potential for innovation and sustainability around the globe.

Compared to traditional dyes, the new super black masterbatch colorants for PA and PET fibers are a more sustainable solution. New super black colors also feature a 30 to 60 percent lower addition rate compared with conventional black masterbatch.

Liquid and solid masterbatch colorants differentiate exterior lights—often without adding enormous cost Solid masterbatch colorants
