Key Performance Features
YIHOO AO PEPQ is a bisphosphate-structured phosphite ester antioxidant, featuring excellent compatibility with base materials and other additives, low volatility, strong hydrolysis resistance, and high thermal stability. Its thermogravimetric decomposition temperature reaches up to 350 °C; it effectively inhibits color yellowing during high-temperature processing and stabilizes the melt flow index of the treated materials. When compounded with hindered phenolic antioxidants, this product delivers outstanding synergistic effects.
Applicable Materials & Dosage
Widely applicable to polyolefins and olefin copolymers (e.g., HDPE, LLDPE, polypropylene, polybutene, EVA copolymers), as well as engineering plastics such as polycarbonate, polyacetal, and polyamide. Also suitable for polyesters, styrenic homopolymers and copolymers, adhesives, natural and synthetic tackifiers, and elastomers (e.g., BR, SEBS, SBS) and other organic substrates.Recommended dosage: 0.1% – 0.5% |
