SperseStab™ TNPP is a liquid phosphite antioxidant and thermal stabilizer for use in elastomers, including SBR, NBR, and SIS. It is highly effective in light-colored solutions and emulsion-polymerized elastomers. It is extremely efficient at preventing gel formation during polymerization, processing, and long-term heat aging. Additionally, this cost-effective process stabilizer finds application in thermoplastic polymers such as polyethylene, polypropylene, polystyrene, and ABS.
