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.
