Used as a heat stabilizer in polyvinyl chloride (PVC) plastics to prevent degradation during processing. It helps maintain the color and structural integrity of PVC products when exposed to high temperatures. Also functions as a lubricant and release agent in plastic and rubber manufacturing. Occasionally used in the production of candles, coatings, and printing inks to improve water resistance and texture. Its use is limited due to the toxicity of cadmium, and it has been largely replaced by safer alternatives in many applications.
