Application
Methyl Tin Mercaptide Heat Stabilizer is currently the plastic heat stabilizer with the most excellent performance, which is very effective for the calendaring, extrusion, injection and blow molding process to produce different kinds of PVC products. It has good balancing of properties giving outstanding initial pigmenting property and excellent both initial and long-term stability. It is recommended to replace other plastic heat stabilizers .
Methyl Tin Mercaptide SW-MTM-S1-155 is a more economical tin stabilizer. It is recommended to use in hard PVC, esp for PVC pipe, profile and transparent cable.

Advantages
High Heat Stability
According to the appraisal of the international authoritative organs, Methyl Tin Mercaptide has the highest heat stability and best early-phase coloring among the organic tin heat stabilizers.
Small Dosage
At the same effect, Methyl Tin Mercaptide enjoys small dosage, 15-20% less than butyl tin and octyl tin, with generally 0.8-1.5 shares.
Excellent Performance
PVC products using Methyl Tin Mercaptide Heat Stabilizer enjoy high transparency and clean color shade.
