Examples include:
• Dyneema®, the world’s strongest fiber™, enables unmatched levels of performance and
protection for end-use applications, including ballistic personal protection, marine and
sustainable infrastructure and outdoor sports
• 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 is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic
Waste and certified Great Place to Work®.
