methyl tin mercaptide

Methyl tin mercaptide Heat Stabilizer(or name:methyl tin stabilizer, pvc heat stabilizer, Organotin Heat Stabilizer; Me-Sn-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.
