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.

A dedicated team is able to scientifically investigate details of the recycling process, understand the degradation and behavior of polymers, and develop the right additive and color masterbatches to increase the performance of PCRs and guarantee high recyclability of the final article.

COLORANTS & ADDITIVES FOR HEALTHCARE Essential polymer solutions for critical healthcare applications WHEN MATERIAL EXPERTISE IS CRITICAL AESTHETIC APPEAL Regulatory compliant and approved masterbatch colors use custom polymer colorants to achieve any shade SPECIAL EFFECTS Enhance your brand and stand apart with pearlescent, metallic, iridescent, fluorescent or thermo-chromatic effects SOLID TO LIQUID SOLUTIONS Choose from a full range of available color solutions, from liquid color to solid product forms ANTIMICROBIALS Efficacy performance and regulatory requirements are met in a wide range of resins compatible with Withstand™ antimicrobial technology SURFACE ENERGY MODIFICATION Additive technologies such as low retention, hydrophobic, lubricious, light diffusion, or anti-stat provide desired surface manipulation Materials used for today’s medical devices, parts and pharmaceutical packaging contribute significantly to performance and, in turn, to a patient’s health and well-being.
