Light yellow oily transparent liquid, relative density 1.066 (20℃), melting point 8℃, flash point 227℃, refractive index 1.468~1.470, viscosity 50mPa (25℃). Insoluble in water, compatible with ethanol, benzene, acetone, ethyl acetate and other general organic solvents and most plasticizers
As a heat stabilizer for PVC, it is the earliest type of organotin heat stabilizer. Good lubricity, transparency and weather resistance, good compatibility with plasticizer, heat resistance is not as good as other kinds of organic tin stabilizer. The main soft transparent products or semi-soft products. It has synergistic effect when used with metal soap such as stearic acid barrier, barium stearate or epoxides. As a lubricant in hard products, it can also be used as a curing agent of silicone rubber and a catalyst for polyurethane synthesis.
