What is organic tin?

(1) Excellent Transparency The greatest advantage of organic tin stabilizers is the excellent transparency, the use of organic tin stabilizer PVC formula, can be crystal-like products. Because of this, organic tin can be used for bottles, containers, corrugated board, various types of rigid packaging containers, hoses, profiles, films and so on.

(2) Exceptional thermal stability There is currently no other type of thermal stabilizer that can be used in thermal 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.

 

(3) product non-toxic Most organic tin stabilizer is non-toxic, combined with organotin stabilizer in the hard PVC in the migration is minimal, therefore, organotin stabilizer is the preferred food contact with PVC heat stabilizer.

 

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

 

(5) Lubricant Poor sulfur-containing tin stabilizers are somewhat 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.

 

(6) Cost is expensive Compared with other types of stabilizers, the overall performance of organotin stabilizer 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.
