(1) Excellent transparency The biggest advantage of organotin stabilizers is that they have excellent transparency. The PVC formulations using organotin stabilizers can obtain crystal-like products. Because of this, organotin can be used in bottles, containers, corrugated boards, various types of rigid packaging containers, hoses, profiles, films, etc.

(2) Excellent thermal stability In terms of thermal stability, there is no other type of thermal stabilizer that can surpass it. Therefore, it is the preferred stabilizer for rigid PVC, and some varieties have better performance in soft products. Applicable to all PVC homopolymers, such as emulsion, suspension and bulk PVC, as well as vinyl chloride copolymers, graft polymers and polymer blends.

(3) The product is non-toxic. Most organotin stabilizers are non-toxic, and the migration of organotin stabilizers in rigid PVC is extremely small. Therefore, organotin stabilizers are the preferred thermal stabilizers for food-contacting PVC. agent.

(4) Good compatibility The organic tin stabilizer has good compatibility with PVC, so there is generally no phenomenon of precipitation on the metal surface that is common in lead salt stabilizer and metal soap stabilizer systems.

(5) Poor lubricity Sulfur-containing tin stabilizers have slightly poor self-lubricating properties. Therefore, many commercially available sulfur-containing organotins are formulated with lubricants to prevent hot melt from adhering to processing equipment during processing. .

(6) Expensive cost Compared with other types of stabilizers, the comprehensive performance of organotin stabilizers is closer to the ideal stabilizer. But all organotin stabilizers, regardless of structure, have the major disadvantage of being much more expensive to manufacture than lead-based stabilizers or metal soap-based complexes. In recent years, the cost of its formulation has been reduced by adopting new synthesis techniques or reducing its use in formulations. In the 1970s, low-priced tin products were developed abroad, which reduced the tin content and reduced the price to a certain extent.
