Regular monitoring of our emissions to air from all of our sites is a part of environmental management at Avient. All Avient manufacturing facilities comply with applicable regulatory requirements regarding emissions limits and hold valid air permits where required. While conventional air emissions are a critical and a highlyinfluential topic in some industrial sectors, as a specialty formulator of purchased materials, Avient’s conventional air emission levels from legacy operations are de minimis and not material.

A weak, less elastomeric material will creep more than a higher strength, more resilient material. Flexural modulus measures the materials’ resistance to bending, and hardness measures the materials’ resistance to penetration. Generally, higher hardness materials have better abrasion resistance.
