FOILING COUNTERFEITERS WITH SPECIALIZED COLOR & ADDITIVE MASTERBATCHES CASE STUDY: COLOR, ADDITIVES & INKS Challe nge Accepted. THE SOLUTION The Avient team proposed multiple solutions—including a laser-marking additive, an authentication additive, and colorant—bundled into a single Smartbatch™ concentrate. The concentrate also included the required color for the manufacturer’s branding and an additive for UV protection.

Sales Director of Color and Additives Asia, 2011 to 2014. See Note 13, Income Taxes, for additional detail. Our additive concentrates encompass a wide variety of performance and process enhancing characteristics and are commonly categorized by the function that they perform, including UV light stabilization and blocking, antimicrobial, anti-static, blowing or foaming, antioxidant, lubricant, oxygen and visible light blocking and productivity enhancement.

Newer molding equipment provides additional options for transferring from injection boost (first-stage Injection) to the pack and hold phase. In addition, the material hardness is a factor. The addition of a slight surface texture to the mold can help to mask possible surface blemishes in the molded article.

See Note 13, Income Taxes, for additional detail. Color, Additives and Inks Color, Additives and Inks is a leading formulator of specialized custom color and additive concentrates in solid and liquid form for thermoplastics, dispersions for thermosets, as well as specialty inks. Our additive concentrates encompass a wide variety of performance and process enhancing characteristics and are commonly categorized by the function that they perform, including UV light stabilization and blocking, antimicrobial, anti-static, blowing or foaming, antioxidant, lubricant, oxygen and visible light blocking and productivity enhancement.

Last year we were excited to launch two additional resource groups. See Note 12, Income Taxes, for additional detail. Our additive concentrates encompass a wide variety of performance and process enhancing characteristics and are commonly categorized by the function that they perform, including UV light stabilization and blocking, antimicrobial, anti-static, blowing or foaming, antioxidant, lubricant, oxygen and visible light blocking and productivity enhancement.

These antibacterial and antifungal additives reduce growth of bacteria, mold and fungus on the surface and through the thickness of the plastic part. WithStand antimicrobial additives can be combined with colorants or other functional additives in a single masterbatch or liquid solution to get the exact performance needed. ANTIMICROBIALS FOR PLASTICS Effective in reducing bacterial growth across a range of polymer resins Bacteria does not attach to surface of part molded with WithStand Bacteria attaches to surface of part molded without WithStand Side View Molded with antimicrobial additives Molded without antimicrobial additives
