And whether they shove off from shore in a kayak, canoe, raft, or SUP, they all want high-quality, durable, lightweight equipment that they can count on to perform flawlessly for their specific needs. Our wide range of advanced polymers and composites give you the freedom to innovate, add strength without weight, and create fresh designs that offer great performance yet remain economical to produce. Some of the information arises from laboratory work with small-scale equipment which may not provide a reliable indication of performance or properties obtained or obtainable on larger-scale equipment.

Avient is fully committed to increasing opportunities to expand the use of recycled polymers, addressing any barriers that arise either during the recycling process or when customers want to incorporate PCR content into existing or new applications,” said Norbert Merklein, vice president and general manager for the Europe, Middle East and Africa regions of Color, Additives and Inks at Avient.
