Heat stabilizer - organic tin

Exceptional thermal stability There is currently no other type of heat stabilizer in excess of heat stability. Therefore, it is the preferred PVC rigid stabilizer, some varieties in the soft products in the performance is also better. Suitable for all PVC homopolymers, such as emulsions, suspensions and bulk PVC, as well as vinyl chloride copolymers, grafted polymers and blended polymers.

Product non-toxic Most organotin stabilizers are non-toxic, combined with the migration of organotin stabilizers in hard PVC, so the organotin stabilizer is the preferred heat stabilizer for PVC in contact with food.

Good compatibility with organic tin stabilizers and PVC compatibility is good, so generally do not appear as a lead salt stabilizer, metal soap stabilizer system commonly found in the metal surface precipitation phenomenon.

Lubricant poorly sulfur-containing tin stabilizers are slightly less self-lubricating, so many commercially available sulfur-containing organotin are formulated with lubricants to prevent hot melt from adhering to the processing equipment during processing.

High cost Compared with other types of stabilizers, the overall performance of organotin stabilizers is closer to the ideal stabilizer. However, all organotin stabilizers, regardless of their structure, have a major drawback that manufacturing costs are much higher than lead-based stabilizers or metallic soap-based complexes.

In recent years, the cost of formulation has been reduced by the use of new synthetic techniques, or by reducing its use in formulations. 70 years, foreign developed low-cost tin products, reducing the tin content, but also to a certain extent, the price can be reduced.
