AI Overview
UV Absorber 326 (often Tinuvin® 326) is a hydroxyphenyl benzotriazole-type UV absorber and light stabilizer used to prevent UV-induced degradation in plastics. It excels in protecting polyolefins (PE, PP) and engineering plastics from discoloration and embrittlement, featuring high heat stability and low volatility.
