Introduction
Revonox® 501 belongs to the benzofuranone family, and optimally combines carbon-centered radical scavenger and primary antioxidant function in one molecule. Being a multi-functional antioxidant, Revonox® 501 provides outstanding performance in a variety of polymers such as PP, PE, PBT, styrenics and adhesives, especially for engineering plastics. Its superior effectiveness over conventional antioxidant systems is particularly pronounced in improved melt flow index (MFI) control, good color maintenance, and long-term thermal stabilization.
Applications
Revonox® 501 can be applied as a high efficient melt processing stabilizer system in polyolefins, styrenics and olefin-copolymers. Revonox® 501 can be blended with hindered phenolic and phosphate-based antioxidants to provide synergistic effect. A dosage of Revonox® 501 as low as 50-100 ppm secures a stable MFI performance, along with reduced yellowing.
