Methyl Tin Mercaptide Introduction

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 ℃.
Methyltin is the most possible organotin product in the field of PVC extrusion, calendering, impact molding and shot molding due to its easy process and affordable.

• Chinese Name: 硫醇甲基锡

• English Name: Methyl Tin Mercaptide

• Chemical Structure Chemical Formula: C31H60O6S3Sn AND C22H44O4S2Sn

• CAS NO: 57583-35-4 <20% & 57583-34-3 <80%

• Synonyms:Methyl tin mercaptide PVC Heat Stabilizer, Methyl tin isooctyl mercaptoacetate stabilizers, Methyl tin Heat Stabilizer, Organotin Heat Stabilizer,Methyl tin mercaptide

  

Mercaptan Methyl Tin Heat stabilizer is the very best stable range. The production approach is as follows: Steel Tin is methylated with chloromethane under the action of temperature level 210-240 ℃, stress 1.0-1.3 MPA as well as Amine Phase-transfer catalyst, after disproportionation response, the material of trimethyltin chloride was regulated to be less than 0.1%, and then responded with isooctyl mercaptoacetate. Organotin commercial selections are generally separated into methyl tin, butyl tin and also Octyl Tin. As a result of its easy procedure, low cost and exceptional performance, Methyltin is one of the most prospective organotin item. Applied to PVC extrusion, calendering, impact molding as well as shot molding of various products, with superb initial coloring, transparency and thermal security, polyvinyl chloride is an essential additive for thin movies, sheets, plates, granular materials, pipelines, installations and also accounts.

The mix of dimethyl Tin Mercaptan and also Methyl Tin Mercaptan is primarily made use of in commercial products. The weight ratio of Mercaptan to dimethyl Tin Mercaptan is 20:80, and also the stability of Mercaptan is exceptional, dimethyl Tin Mercaptan displays better late security. Methyl Tin Mercaptan is approved by United States FDA (21CFR 178.2010) and also BGA (II A, 4C). It can be used in food product packaging products and also water pipes. As a result of its excellent performance, it can be utilized in the processing of food-grade tough transparent items with high processing needs.
