Zheng Bang’s PSA-100 Free Radical Scavenger is a high-purity compound of 2,6-di-tert-butyl-4-methylphenol, which is widely used as an inhibitor in the polymerization of styrene, butadiene and other monomers. It can also act as an antioxidant in polymers and oils, and a stabilizer in various organic compounds. As an inhibitor, PSA-100 traps free radicals that could lead to chain termination and crosslinking during polymerization. This results in a more controlled and efficient polymerization process with improved molecular weight distribution and reduced gel formation.
