Methyl Tin Mercaptide

CS18methyl tin mercaptide is a colorless or light yellow transparent liquid, and a weak acidic ester compound. It is solvable in most organic solvents, and if contacting water it will become turbid due to hydrolysis, and even its use performances will be affected. It is non-flammable and non-explosive and belongs to general chemical substance instead of state-regulated goods. T-CS11 is methyl tin mercaptide is an effective heat stabilizer and through the adjustment of inner structure it will render the product well combination of excellent property to inhibit the initial coloring and initial heat stability. It has strong anti-oxidation, can decompose peroxides and capture free radicals in the product, is compatible with PVC, and during the processing it never affects the physical and mechanical properties and processing features of polymer, The effective odor-removing technology renders the product extremely low bad odor and it is widely used in such PVC products as medical film, sheet.

FETURES

1. Excellent Thermal Stability

Processing Temperature Tolerance: PVC calendering film using methyl tin mercaptan maintain excellent stability even in high-temperature environments, allowing processing at higher temperatures without degradation.

2. Excellent Weather Resistance

UV Resistance: Methyl tin mercaptan absorbs and protects against UV rays, reducing aging, discoloration, and brittleness of PVC materials caused by sunlight exposure.

3. Improved Processability
4. Enhanced Mechanical Properties

Enhanced Toughness: Due to its thermal stabilizing effect, methyltin mercaptan helps maintain the toughness of PVC calendering film during temperature fluctuations and long-term use, preventing brittle cracking and fracturing.  

APPLICATIONS

Transparent and opaque soft products: plastic hoses, printed films, shrink films
