Uses

 

Catalyst: catalyst Dibutyltin Maleate is Widely used as a tin catalyst in organic synthesis reactions, such as polymerization and esterification reactions.
Heat stabilizer: Heat stabilizer used for polyvinyl chloride (PVC), especially hard transparent products (such as pipes and plates). Its advantages include excellent heat resistance and transparency, preventing the product from yellowing during high-temperature processing; using it in combination with barium soap, cadmium soap or epoxy compounds can enhance the stabilizing effect; using it in combination with dibutyltin laurate can improve transparency.
