With robust raw material testing and a comprehensive change control policy, these medical-grade concentrates and pre-colored formulations can help minimize risk and avoid non-compliance. Materials can also be enhanced with functional additives to meet stringent product performance requirements. Processing conditions can cause material properties to shift from the values stated in the information.

Cesa™ Unify™ A4R Polyolefin Compatibilizer for Enhanced Recycling RECYCLED MATERIAL IN A CHANGING MARKET Legislation globally is driving change towards increased quantities of post-consumer recycled (PCR) materials, further encouraged by the implementation of usage targets and new tariffs. Both legislation and industry goals have created an increased demand for recycled material across the plastics industry, but especially within the packaging market. Processing conditions can cause material properties to shift from the values stated in the information.

They can also be part of the chemical foaming process, achieving a material expansion of up to 50%. They can improve cable insulation and electrical properties and reduce overall material usage and cable weight. Processing conditions can cause material properties to shift from the values stated in the information.

Biopolymers may be manufactured from renewable materials such as corn and sugar cane and can be biodegradable, meaning they degrade under biological—mainly microbial—conditions. The pigments and ingredients contained in Avient’s bio colorants have been tested in independent laboratories who assessed the compliancy of those materials according to standard EN 13432 for content of heavy metals, and toxicity to plants. Processing conditions can cause material properties to shift from the values stated in the information.
