MEDICAL DEVICE DISINFECTION—HOW TO PREVENT CRACKING AND CRAZING Understanding polymer performance is key to minimizing disinfectant-related failures DISINFECTANT-RELATED DAMAGE ON POLYMER HOUSINGS Strong chemicals used to reduce hospital- acquired infections can damage equipment and result in material failures, such as: • Stress cracking • Crazing • Discoloration CHEMICAL RESISTANCE REQUIREMENTS VARY BY ENVIRONMENT • Patient/exam rooms • Operating and radiology rooms • Reception areas • Home (patient equipment & devices) Healthcare devices must perform flawlessly in a myriad of challenging environments and engineers must be certain their devices can withstand increasingly potent disinfectants, which have begun to outstrip the performance of traditional polymers. Additionally, the wide variability of environments that medical devices might see, which can range from home to hospital, mean devices must be able to withstand varying disinfectant strengths, exposure levels and frequencies. Whether you are designing for a medical device housing or a surgical device in the operating room, we offer solutions to meet a wide variety of performance specifications and application needs.

These customizable color solutions enhance brand value and promote product differentiation for medical device, cosmetic, or pharmaceutical polymer applications. OnColor HC Plus Colorants have been tested across a wide range of medical polymers to provide added confidence in meeting these critical bio- compatibility standards. KEY CHARACTERISTICS • Polymer colorants formulated specifically for healthcare product applications • Meets and exceeds various material performance requirements including FDA 21 CFR, ISO 10993 and USP Class VI • HC Plus colorants certified for bio-compatibility • Available as pre-color, concentrate, masterbatch or Smartbatch™ combined colorant/additive solution • Wide range of colors, striking special effects and custom color matching MARKETS AND APPLICATIONS OnColor™ HC and HC Plus Colorants are an excellent choice for medical devices and parts, pharmaceutical or cosmetic packaging, and many other healthcare related polymer applications.
