What does organotin stabilizer do to pvc

Organotin stabilizer (tin thioglycolate) can replace the unstable Cl atom on the polymer, so that the PVC resin has long-term stability and initial color retention12 . The stabilization mechanism of tin thioglycolate is that S atoms can replace unstable Cl atoms, thus inhibiting the formation of conjugated polyenes. Organotin stabilizer is one of the most…
