SPECIALTY ENGINEERED MATERIALS PRODUCT SELECTION GUIDE The product design and material specification process can be daunting. From material selection to technical support, we’re here to help you drive your product from concept to reality. Processing conditions can cause material properties to shift from the values stated in the information.

PRODUCT BULLETIN Cesa™ Nox A4R Additives for Recycling Polyolefin Antioxidant for Enhanced Recycling RECYCLED MATERIAL IN A CHANGING MARKET Legislation globally is driving change towards increased quantities of post-consumer recycled materials (PCR), further encouraged by the implementation of usage targets and new tariffs. Protecting PCR from degradation in this way can help achieve higher quality levels of recyclate and better end-use products and improve the quality of the overall recycling stream due to its long term stabilizing effect. Processing conditions can cause material properties to shift from the values stated in the information.

Consistency and reliability in those materials are imperative for components designed to heal or even save lives.
