Product Description

Product Description

Methyl Tin Mercaptide Description

Methyl tin mercaptide is one of the three kinds of Organotin(methyl tin, butyl tin, and Octyl Tin). As a transparent, clear, and viscous liquid, it exhibits excellent compatibility with polyvinyl chloride (PVC). Serving as a critical heat stabilizer in PVC processing, it boasts superior pre-stability and post-stability, while also enhancing the transparency of the final product. Furthermore, it demonstrates high compatibility with other additives and raw materials, and its weather resistance outperforms that of other metal-based heat stabilizers.
This compound is compatible with weakly polar oils, including C8-C12 fatty alcohols, C8-C12 fatty acids, fatty alcohol phosphites, and various mineral oils. Non-flammable by nature, it features a low freezing point—remaining a viscous liquid even at temperatures as low as -20 ℃.
Owing to its straightforward production process and cost-effectiveness, methyl tin mercaptide stands out as one of the most promising organotin products for PVC processing methods such as extrusion, calendering, blow molding, and injection molding.

Advantages of Methyl Tin Mercaptide

1. Excellent Heat Stabilizer Properties: Ensures optimal stability during the PVC processing under heat.

2. Excellent transparency: Endows PVC products with high – level clarity.

3. Non-toxic: It is safe and environmentally friendly.

4. Outstanding Compatibility: Blends well with other additives and raw materials in PVC production.

5. Better Liquidity: Facilitates smooth processing of PVC materials

6. Strong Resistance to Scaling: Minimizes scaling issues during production.
