Lead Stearate (CAS 1072-35-1) is a compound that holds significant importance in the chemical industry, particularly for its role as a stabilizer in PVC (Polyvinyl Chloride) formulations. As a leading manufacturer and supplier, we are committed to providing insights into the properties that make Lead Stearate such a valuable industrial chemical. Understanding these characteristics is key for any formulator or procurement manager looking to optimize their production processes.

The primary function of Lead Stearate in PVC is to act as a heat stabilizer. PVC is inherently susceptible to thermal degradation when exposed to heat during processing. This degradation can manifest as discoloration, embrittlement, and loss of mechanical strength. Lead Stearate effectively counteracts these effects by scavenging the hydrogen chloride (HCl) released during thermal decomposition, thereby preventing autocatalytic degradation. This stabilizing action is crucial for achieving the desired longevity and performance in a wide array of PVC products, from pipes and window profiles to cables and films.

Beyond its exceptional heat stabilization capabilities, Lead Stearate also offers notable benefits in terms of light fastness and stain resistance. These properties are vital for PVC products that are exposed to environmental factors like sunlight and potential staining agents. The compound helps maintain the aesthetic appeal and structural integrity of the final product over time, which is a significant advantage for manufacturers. When you buy Lead Stearate for these applications, you are investing in enhanced product quality and customer satisfaction.

From a chemical standpoint, Lead Stearate typically presents as a white powder. Its physical form and chemical structure are optimized for dispersion within PVC matrices. The technical specifications, such as a melting point typically ranging from 98-110°C and a specific lead content, are critical parameters that our manufacturing process meticulously controls. These precise specifications ensure predictable performance and reliable results in your formulations.

For businesses seeking to source this vital additive, partnering with a reputable supplier is paramount. We, as a China-based manufacturer, ensure that every batch of Lead Stearate we produce meets rigorous quality standards. Our focus on consistent quality, coupled with competitive pricing and a reliable supply chain, makes us an ideal partner for companies worldwide.
