Lead based Compound Stabilizer

Lead based composite stabilizer is a commonly used additive widely used in the plastic processing industry. It can improve the thermal stability and mechanical properties of plastics, and extend the service life of products.Lead based composite stabilizers are composed of lead salts and organic acid salts, with lead salts being the main stabilizer component. Lead salts can react with chlorides or acidic substances in plastics to form stable compounds. This compound can absorb and neutralize acidic substances in plastics, preventing their decomposition and production of harmful gases. At the same time, lead salts can also absorb and disperse heat energy in plastics, improving the thermal stability of plastics. Organic acid salts are auxiliary components of lead based composite stabilizers, which can enhance the stability of lead salts and reduce their toxicity. Organic acid salts can form more stable compounds with lead salts, thereby improving the effectiveness of stabilizers. At the same time, organic acid salts can also reduce the solubility of lead salts and reduce the risk of their release into the environment.
