pvc heat stabilizer (w-181)

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).
