High-performance hindered phenolic antioxidant offering exceptional thermal and oxidative stability.
Excellent compatibility with polyolefins, including polyethylene (PE) and polypropylene (PP).
Low volatility and high melting point ensure minimal loss during high-temperature processing.
Effective in both melt-phase and long-term aging protection, extending product service life.
Non-staining and low-color formation, suitable for light-colored and demanding aesthetic applications.
Polypropylene (PP) fibers and nonwovens for automotive interiors and hygiene products.
Blown and cast polyethylene (PE) films used in packaging and agricultural applications.
Injection-molded PP and HDPE components in household appliances and consumer goods.
Rotomolded tanks and large PE/PP parts requiring extended thermal stability during processing.
Cable compounds and insulation materials where long-term electrical integrity is critical.
