Coupling Agents / Compatibilizers

Coupling agents and compatibilizers are essential additives in the plastics industry, typically appearing as fine powders or liquids. Key features include improved mechanical properties, enhanced processability, and increased durability. Suitable for applications in automotive parts, packaging, and construction materials. 

Alternatives to coupling agents and compatibilizers include using higher concentrations of primary stabilizers alone. A notable trend in the industry is the increasing use of these agents in recycling processes to create value from mixed plastic waste. Sub-types include silanes, maleic anhydride grafted polymers, and epoxy-based compatibilizers.
