Yparex® 10403 is a family of maleic-anhydride-(MAH)-functionalized polyolefins, specifically a PE-based concentrate, designed for use as a compatibilizer and coupling agent in various applications. It is based on maleic anhydride-(MAH)-modified and functionalized polyolefin compounds, which make it an ideal coupling agent and compatibilizer.

Yparex® 10403 contains maleic anhydride grafted (MAH) polymer content and possesses a good melt flow index, making it suitable for processing by compounding, blown and cast film. It acts as a compatibilizer, coupling agent, and impact modifier for polyamide 6, resulting in a significant increase in notched and unnotched impact strength.
