Dibasic Lead Stearate: Key Properties for PVC Stabilization
Dibasic Lead Stearate (CAS 56189-09-4) is a crucial additive in the chemical industry, particularly for enhancing the performance of Polyvinyl Chloride (PVC). As a leading manufacturer and supplier, understanding its key properties is vital for procurement managers and R&D scientists looking to optimize their formulations. This article delves into the essential characteristics that make Dibasic Lead Stearate indispensable.
Firstly, Dibasic Lead Stearate is renowned for its exceptional heat stabilization capabilities. During the processing of PVC, which often involves high temperatures, the material can degrade. Dibasic Lead Stearate acts as a scavenger for the hydrochloric acid (HCl) released during this process, effectively neutralizing it and preventing autocatalytic degradation of the polymer chain. This property is critical for producing durable PVC products such as pipes, profiles, and cables. For companies looking to buy reliable PVC stabilizers, Dibasic Lead Stearate offers a proven solution.
Secondly, its role as a lubricant is equally significant. Dibasic Lead Stearate provides both internal and external lubrication for PVC. Internal lubrication reduces the friction between polymer chains, leading to lower melt viscosity and improved processability. External lubrication reduces friction between the polymer melt and processing equipment, preventing sticking and ensuring smoother extrusion or molding. This dual lubrication effect is highly valued by product formulators seeking to improve manufacturing efficiency and product finish.
Furthermore, the compound offers good water resistance and electrical insulation properties. These attributes make it particularly suitable for applications like wire and cable jacketing, where protection against moisture and electrical current is paramount. The consistent quality and supply from manufacturers like us ensure that these properties are reliably delivered in every batch.
The physical appearance of Dibasic Lead Stearate is typically a white powder, with a specific chemical formula (C36H70O6Pb2) and CAS number (56189-09-4). Its solubility characteristics are also important; it is generally insoluble in water but soluble in organic solvents when heated, often forming gels upon cooling. This behavior is a key consideration when incorporating it into various formulations.
