NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to illuminating the world of industrial chemicals. Today, we focus on Lead Stearate, a versatile compound with significant industrial applications. Understanding its chemical nature and functional benefits is key to appreciating its role in modern manufacturing processes. From its physical characteristics to its performance enhancements, Lead Stearate is a compound worth exploring.

Lead Stearate, chemically known as Lead(II) octadecanoate or Lead distearate, is typically a greasy, wax-like solid or a fine white powder. Its chemical formula is C₃₆H₇₀O₄Pb, and it is largely insoluble in water but can dissolve slightly in organic solvents like ethanol and ether. The compound's melting point is around 103-110°C, and it decomposes before boiling. A crucial aspect of its specification is the Lead Oxide (PbO) content, typically around 27.5% ± 0.5%, and a low heating loss percentage, usually less than 0.3%. These precise specifications are critical for its efficacy in various applications, particularly as a lead stearate PVC stabilizer.

One of the most prominent applications of lead stearate in manufacturing is within the polymer industry, specifically as a heat stabilizer and lubricant for Polyvinyl Chloride (PVC). In PVC processing, it combats thermal degradation, which can occur at high processing temperatures. By neutralizing released HCl, it prevents the material from breaking down, ensuring the final product retains its intended properties and appearance. The benefits of lead stearate in PVC also include its role in enhancing light stability and minimizing initial staining, which are crucial for aesthetic quality in products like window frames and decorative films.

Furthermore, Lead Stearate serves as a lubricant in various industrial contexts. In paints and coatings, it acts as an anti-precipitation agent, ensuring uniform dispersion of pigments and preventing sedimentation. In the petroleum industry, it functions as a corrosion inhibitor. Its lubricating properties are also leveraged in the formulation of greases. The excellent lead stearate heat resistance and lubricating capabilities make it a valuable additive across these diverse sectors.

For businesses looking to source this chemical, understanding the market and reliable suppliers is essential. Many manufacturers seek a dependable lead stearate supplier China to ensure quality and competitive pricing. The availability of this product for purchase online has also increased accessibility for businesses worldwide.
