Methyl Tin Mercaptide Heat Stabilizer (called 181 for short) is currently the plastic heat stabilizer with the most excellent performance, which is very effective for the rolling, extrusion, and injection molding of hard PVC. Due to its high safety, it is especially applicable to food packing and hard PVC products (such as transparent fake materials, plate materials and heat contracting membranes). Moreover, it has been widely applied to plastic doors and windows, water pipes, decorating materials, so as to replace other plastic heat stabilizers that has high toxicity. Therefore it has been widely used in USA, Europe, Japan. Over the recent years, 181 has been applied in a large quantity. Because 181's stability is much better than other organic tin stabilizer,the relevant products have better performance. So it has been widely welcomed by many large-scale PVC-proccessing enterprises, becoming the key adjuvant in the processing of hard PVC.

Depending on its strong research and development capability, Hangzhou Shengxiang Chemical Co., Ltd. has developed the Methyl Tin Mercaptide Heat Stabilizer. According to the tests of authoritative research organs and relevant departments, every indexes of it has reached the domestic leading level.On the basis of the trial operation in the workshops of respective plastic-processing enterprises, its appearance, transparency, plastification,and heat stability conform to the those of exported same products.

[High Heat Stability]
According to the appraisal of the international authoritative organs, 181 Methyl Tin Mercaptide has the highest heat stability and best early-phase coloring among the organic tin heat stabilizers.

[Small Dosage]
At the same effect, 181 Methyl Tin Mercaptide enjoys small dosage, 15-20% less than butyl tin and octyl tin, with generally 0.8-1.5 shares.

[Reliable Safety]
Authorized by FDA for application as food packing materials with the maximal dosage of 2%.

[Excellent Performance]
PVC products using 181 Methyl Tin Mercaptide Heat Stabilizer enjoy high transparency and clean color shade.
