  • Applications

    Octyltin tris(2-ethylhexyl thioglycolate) (CAS 27107-89-7) is an organotin mercaptide complex used primarily as a heat stabilizer for polyvinyl chloride (PVC) and related thermoplastic polymers, helping to suppress dehydrochlorination and discoloration during high-temperature processing. It is also employed as a processing stabilizer and additive in polymer formulations to enhance thermal stability and durability of coatings, inks, and adhesive systems based on plastics. In electronics-related applications, it serves as a stabilizing component in polymer insulation such as cable jackets. Additionally, it may function as a catalyst or co-catalyst in certain polymerization or curing processes.
