CYANOX 2777 is a highly effective antioxidant phosphite blend that provides superior processing and long term thermal protection for polymers. As a free flowing white powder with a melting point of 166-171°C, CYANOX 2777 has low odor and color contribution and is highly resistant to discoloration and gas fading. CYANOX 2777 demonstrates excellent gas fade resistance for polyolefins as indicated by the low yellowness index values for LLDPE film and tape after NOx exposure. These properties of CYANOX 2777 make it very suitable for applications in the Advanced Materials industry where long term thermal and oxidative stability of polymers is important. CYANOX 2777 at 0.09-0.12% concentration provides effective protection against degradation for polyamides, styrenics, polyurethanes, polyesters and other polymers commonly used in the Advanced Materials industry.
