CHEMICAL NAME : Methyl Tin Mercaptide

FORMULA : C22H44O4S2Sn

CAS NO. : 57583-35-4

 

Description:

Mercaptan methyl tin is just one of the three type of Organotin. It is a clear, clear, and also thick liquid with good compatibility with PVC. It works with weak polar oils such as C8-C12 fatty alcohol, C8-C12 fat, phosphite fatty alcohol ester, and also oil. It is non-flammable and has a reduced freezing point, it is a viscous fluid even at-20 ℃.

Applications:

Methyltin mercaptide or DMTEHTG is an organotin compound. It is a colorless, transparent, low-odor liquid that can be used as an additive in plastics.Methyltin mercaptide is characterized by its high heat stability, particularly good early coloring and is used as a heat stabilizer for hard and soft PVC. It stabilizes rigid polyvinyl chloride polymers and vinyl copolymers, which can be used in food packaging.

Methyltin mercaptide stabilizers are a good choice for blow molding formulations, as well as for vinyls that are rigid and clear when contact with food cannot be ruled out and when a reduced stabilizer smell is desired during processing or in the final product.
