When even harder plastics are measured, instruments with sharper indenters and stronger forces such as Rockwell hardness testers are used. When heated (for example, for molding), the individual chains slip, causing plastic flow. These cross bonds prevent the individual chains from slipping, thus preventing plastic flow when heat is added.

Examples include: • Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint • Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility Avient employs approximately 9,300 associates and is certified ACC Responsible Care® and a founding member of the Alliance to End Plastic Waste. Our customers value the breadth of our solutions as we can tap into a broad array of raw materials to solve their specific needs. Our formulation expertise supports material science decisions, while our processing expertise guides customers to use the materials properly.
