BANKASTAB® MT-620 Heat Stabilizer is a highly efficient Liquid Methyl Tin Mercaptide designed to stabilize Rigid Polyvinyl Chloride and Flexible Polyvinyl Chloride copolymers.


BANKASTAB® MT-620 provides good early colour as well as excellent dynamic processing stability. Its good residual stability also allows for the efficient use of rerind. This non lubricating stabilizer has proven to be 15% to 20% more effective when compared on an equal part basis to Octhyl Tin Mercaptide and Butyl Tin Mercaptide stabilizers in clear rigid PVC bottle and rigid/ soft film formulations.


BANKASTAB® MT-620 is suitable for food packaging applications as defined by BGA, FDA, REACH and other regulatory agency worldwide.
