About Avient Avient Corporation (NYSE: AVNT) provides specialized and sustainable materials solutions that transform customer challenges into opportunities, bringing new products to life for a better world. They are based on management's expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements.

Working together to understand the unique requirements for the company’s conveyor application, the engineering team at Avient developed customized flat springs that provide more consistent quality and longer fatigue life than the original components, improving conveyor performance and longevity. THE IMPACT Not only did the Gordon Composites vibratory springs outperform the company’s originally specified spring components, they provided a number of additional benefits: Ready-to-install springs reduced labor and simplified installation Unlike alternative springs, Gordon Composites springs are factory machined to the required size and pre- drilled for a significant reduction in cutting and drilling processes and allowing valuable labor time to be allocated elsewhere.

Propellers made from polymer composites have a number of benefits over steel and aluminum alternatives, including improved impact resistance and vibration damping properties. And, because they are formed by injection molding, long fiber reinforced thermoplastics can be easily customized to specific design requirements.
