Phenothiazine Prills

Phenothiazine Prills by WeylChem International acts as a radical scavenger/antioxidant. It is available as yellow to greenish prills. It can be used at high temperatures and under oxygen-free conditions. It increases lifetime of synthetic rubber (chloroprene) in order to improve their durability. Addition of 200-3000 ppm of Phenothiazine Prills is sufficient in most cases to inhibit premature polymerization of acrylic acid, methacrylic acid, acrylates and vinyl compounds and thereby increases their stability during production and storage.
