Tin stabilizers
Tin (organotin) stabilizers are among the most effective additives for preventing thermal degradation of PVC during the processing process. They provide exceptional transparency in finished products and high color stability, surpassing lead and calcium-zinc analogues in these parameters.
More
There are several types of tin stabilizers, and sulfur-containing derivatives are common in Russia and most countries, with the exception of the United States:
- Mono- and dimethyltin mercaptide: the most common type, providing excellent initial color reproduction and long-term stability.
- Mono- and di-octyltin mercaptide: characterized by low toxicity and approved for use in food-contact materials.
Advantages and Benefits
- Transparency: the above products are ideal for the production of transparent films and sheets, as they do not cause clouding.
- Thermal stability: effectively protect the polymer at high temperatures during extrusion and injection molding.
- Low dosage: high efficiency allows for lower dosages compared to other types of stabilizers.
- Safety: the above-mentioned organotin compounds are considered more environmentally friendly and have approval for food packaging and medical devices (octyltin in Europe, methyltin in many other countries).
Applications
- Packaging: Food containers, blisters, and shrink films.
- Medicine: Blood transfusion systems, catheters, and drug containers.
