🧪Product Overview

Methyl tin stabilizers are highly efficient organic tin-based PVC heat stabilizers with the following core advantages:

Outstanding Performance: Significantly superior to traditional organic tin stabilizers in terms of stability, transparency, compatibility, and weather resistance, particularly suitable for high-transparency rigid PVC products.

Safe and Non-Toxic: Complies with stringent standards such as the EU RoHS and US FDA, making it suitable for safety-sensitive applications such as food packaging (e.g., cling film, beverage bottles), pharmaceutical packaging, and drinking water pipes.

Cost-Effective: Requires 15–20% less dosage than comparable products to achieve the same performance, thereby reducing overall costs.

🔬 Key Specifications

Chemical Type: Methyl tin thiolates (such as dimethyl tin/monomethyl tin derivatives)

Appearance: Transparent homogeneous liquid, free of visible impurities

Tin Content: ≥19.2%, ensuring high thermal stability performance (high active ingredient content, enhancing cost-effectiveness)
