Application
Methyltin 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 moldnig process to produce differenct 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 that has toxic or low-toxic properties.
Methyl Tin MercaptideSW-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.
