SperseStab™ TNPP

1 of 26 products in this brand
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.

Functions: Antioxidant, Heat Stabilizer, Stabilizer

Compatible Polymers & Resins: Nitrile Butadiene Rubber (NBR), Polyethylenes (PE), Polypropylenes (PP), Polystyrenes (PS), Styrene Butadiene Rubber (SBR), Styrene Butadiene Styrene (SBS)

Features: Cost Effective, Good Thermal Stability, Low Color Formation, Low Migration, Non-Staining, Non-discoloring, Prevents Gel Formation

Synonyms: Tris (4-Nonylphenyl)Phosphite, Tris(P-Nonylphenyl)Phosphite
