TRIS(77-86-1) as a heat stabilizer for polyvinyl chloride

The synergistic effect of TRIS(77-86-1) and 1,3-dimethyl-6-aminopyrazine as the heat stabilizer of polyvinyl chloride was studied by static thermal aging, dehydrochlorination and dynamic thermal stability experiments. The results show that PVC has the best static and dynamic thermal stability when used together with TRIS(77-86-1) with 2: 1, and is superior to the effect of pentaerythritol and DMAU, diethanolamine and DMAU.
