Cadmium organic salts, commercially cadmium stearate or cadmium laurate containing 1 - 16% cadmium, are the most effective stabilizer for polymers especially for PVC and its related products to develops good initial colour and clarity as well as to retard the degradation against heat and UV. These stabilizers allow high temperature process. These compounds are forbidden in food packaging applications. However, They are not replaced with other stabilizer for outdoor applications such as profiles, pipes, hoses and electrical insulation of the same effectiveness.
