Avient’s range of medical-grade polymers, colorants, and additives can enhance the safety and effectiveness of these devices while helping manufacturers mitigate risks when bringing products to market. Hand-held devices that can be color-coded for easy branding and identification. Hand-held devices that can be color-coded for easy branding and identification.

It creates different visual textures that can look like one color when viewed from a distance but, when viewed close-up, can appear to have a grading effect. Both polypropylene and polyester yarns in mono and three-color yarns can be spun on this line. Avient Corporation provides specialized and sustainable material solutions that transform customer challenges into opportunities, bringing new products to life for a better world.

Furthermore, it can be combined with polymer colorants where color design is desired in a mold release application. Limiting Damage: By acting as a lubricant, Evoluscend™ additive can help limit mold damage, supporting the longevity and quality of the mold and the plastic products Avient Corporation provides specialized and sustainable materials solutions that transform customer challenges into opportunities, bringing new products to life for a better world.Examples include:
