CAS 57583-35-4 Methyl Tin Mercaptide Liquid Methyltin Mercaptide For PVC Industry

 

Product Description

Methyltin mercaptide refers to a class of organotin compounds that are used as heat stabilizers in the PVC (polyvinyl chloride) industry. They are typically liquid or semi-solid substances composed of methyltin cations and mercaptide anions.

 

Description:

• Chemical Formula: The specific chemical formula of methyltin mercaptides can vary depending on the specific compound within this class. Examples include methyltin tris(2-ethylhexylmercaptoacetate) and methyltin tris(isooctylmercaptoacetate).
• Physical State: Methyltin mercaptides are usually liquids or semi-solids at room temperature. They may have a light color, ranging from pale yellow to amber.

Specifications:

Item	Specifications	Results
Appearance	Light yellow clear liquid	Conforms
Tin Content	≥19.0%	19.01%
Color (Pt-Co)	≤100	20
Specific Gravity (20°C)	1.17~1.19	1.170
Viscosity (25°CPa·S)	0.020~0.080	0.053

 

Features:

• Heat Stabilization: Methyltin mercaptides are primarily used as heat stabilizers in the production of PVC. They help prevent degradation of the polymer during processing and exposure to high temperatures, ensuring the durability and stability of PVC products.
• Synergistic Effect: Methyltin mercaptides are often used in combination with other stabilizers, such as organotin carboxylates or calcium-zinc stabilizers, to achieve optimal heat stabilization and provide improved performance.
• Compatibility: They exhibit good compatibility with PVC and other additives commonly used in PVC formulations.

Applications:

• PVC Industry: Methyltin mercaptides are widely utilized as heat stabilizers in the production of PVC-based products, including pipes, profiles, cables, films, and sheets. They help maintain the desired physical properties, color, and thermal stability of PVC during processing and subsequent use.
• Other Polymer Applications: In addition to PVC, methyltin mercaptides may find limited applications as heat stabilizers or additives in other polymer systems where heat stability and processing conditions are critical.
