YT-181 Methyl tin Mercaptide Stabilizers


YT-181 is an efficient general-purpose methyltin based heat stabilizer which is suitable to be used in calendaring, extrusion, injection and blow molding process to produce food-contact PVC and its polymers such as rigid clear PVC sheet, plate, pipe, bottle and other profiles as well as flexible clear film, etc.. It has good balance of properties giving outstanding initial pigmenting property and excellent both initial and long-term stability, which is required in manufacturing of high performance PVC, particularly for rigid sheet and film applications. By introducing high efficiency deodorization technology, odor of YT-181 is very weak. It can be applied to produce PVC packaging materials in contact with food and drug directly, and provide much more excellent processing performance than other toxic or low-toxic addictives.


YT-181 is a clear colorless or pale yellow liquid with weak odor. It is soluble in most organic solvents. It will hydrolyze in contact with water and become hazy or cloudy, which will severely affect its performance.

Packed in polytetrafluoroethylene (PTFE) lined iron drums or polypropylene drums of 220kg net each. Other packaging is also available upon request.


Store in dry and well-ventilated places. Seal the drum immediately to protect product from contacting with moister and air after use. Avoid contact with water. When handling the product, operators should wear suitable protective clothing. In case accidentally contact with skin, flush with water immediately.

It is recommended to use plastic, stainless steel of glass containers instead of common iron ones to store and transfer the product. Please refer to “Material Safely Data Sheet” (MSDS).
