Cesa™ Tough™ A4R

Cesa™ Tough™ A4R by Avient (Formerly PolyOne) is an additive for recycling. This advanced polyolefin additive technology is developed to significantly enhance the environmental stress crack resistance (ESCR) of recycled high-density polyethylene (r-HDPE), enabling increased use of post-consumer recycled (PCR) content in demanding applications.

• It modifies polymer rheology and strengthens polymer architecture to improve resistance against degradation and stress cracking in aggressive service environments, while maintaining the recyclability of the material.
• It improves overall mechanical and processing properties by increasing melt flow by over 20% for enhanced processability, strain at break by more than 35% to reduce the risk of material failure, and impact strength by over 140% to extend product durability and service life.
• These enhancements allow manufacturers to push PCR content further without compromising performance, durability, or regulatory compliance.
• It is used in demanding applications such as cable jacketing, piping, and load-bearing packaging.
• Cesa™ Tough™ A4R meets EU regulations as well as sustainability goals.
