Features & Benefits

Materials Features: Extraction Resistant,
Good Color Stability,
Low Volatility,
Odorless,
Prevents Thermo-Oxidative Degradation
Product Features: It can be used in styrene polymers, particularly impact-modified polystyrenes, ABS, MBS, SB, and SBR latices, as well as in POM homo- and co-polymers. It is also very useful for the stabilization of polyurethanes, polyamides, thermoplastic polyesters, PVC, and other polymers. In addition to imparting thermostability to the finished polymer, it is effective as a chain stopper during PVC polymerization.
