OnColor™ Color Concentrates for Non-Phtalate PVC Formulations Plasticizers are a major component in PVC formulations. There are different chemistries, including formulations that contain phthalates and non-phthalate plasticizers. Due to the rise in non-phthalate plasticizer demand, Avient offers a range of color concentrates suitable for these formulations.

Additionally, plastic prefilled syringes can be color-coded for easy identification and customized to meet specific opacities in polypropylene (PP) resin, while laser marking additives can help create precise, solvent-free markings.  Formulated with pre-tested raw materials, this range of additives helps enhance the performance and functionality of plastics used in medical devices and pharmaceutical packaging and mitigate the risk of non-compliance.

Plastics are a preferred material for IVD devices and kit components due to their inherent properties, customizability, and lightweight nature. Find out how part design can reduce stress in molded plastic parts and improve ESCR in your products
