OnFlex™ LO Low VOC/ Fog Thermoplastic Elastomers OnColor™ FX Special Effect Colorants Human Health & Safety Solutions that directly protect and preserve human health (e.g., Hygiene & Personal Protective Equipment (PPE) and medical devices) Mevopur™ Polyolefin-based Formulations and Masterbatches Versaflex™ HC Thermoplastic Elastomers Contains Recycle Content: Incorporates post-consumer or post-industrial recycle content. ColorMatrix™ Optica™ Toners Blue toners and colorants work to correct and reduce the yellowing or color variation that typically occurs during the recycling process. Mevopur™ ProTect Oxygen Scavenger extends shelf life for PET pharma packaging by limiting oxygen (O2) degradation for drugs and nutraceuticals stored in bottles, even in transparent mono-layer versions.

Figure 18 shows how Versaflex™ CE 3320-70 TPE resists staining from rubbing against blue jean material containing dye. Figure 18: Blue jean stain resistance testing UTILIZING ENGINEERING SIMULATIONS Engineering simulations with advanced computer software can be used to evaluate a variety of product performance criteria and address important questions related to ergonomic design.

Mevopur™ Healthcare Colorants and Formulations: a range of medical grade concentrates and pre-colored formulations for a wide range of polymers used in applications such as remote patient monitoring, circulating blood contact, and invasive devices, with pre-tested biocompatibility according to ISO 10993, change control in place, production certified to ISO 13485-2016 and DMF/MAF files available

Also, the natural color for high-performance thermoplastics is yellow or brown, which makes achieving blues and grays much harder.
