Dibasic Lead Stearate (DBLS)

Product Description: Dibasic Lead Stearate (DBLS)

Dibasic Lead Stearate (DBLS) is a versatile chemical compound widely used as a heat stabilizer and lubricant in the manufacturing of PVC (polyvinyl chloride) products, rubber compounds, and various other applications in the plastics and rubber industries. With its unique properties, DBLS offers excellent thermal stability, lubrication, and processing benefits, making it an essential additive in polymer formulations.

Key Features:

Heat Stabilization: Dibasic Lead Stearate acts as an effective heat stabilizer, preventing the degradation of polymers during processing and prolonged exposure to elevated temperatures. It inhibits thermal degradation reactions, such as thermal oxidation and chain scission, preserving the mechanical and physical properties of the polymer.

Lubrication: DBLS exhibits excellent lubricating properties, reducing friction and enhancing the flow properties of polymer melts during processing. It facilitates smooth extrusion, molding, and calendering operations, improving processing efficiency and product quality.

Good Gelation Efficiency: Dibasic Lead Stearate demonstrates good gelation efficiency, promoting fusion and homogenization of PVC resin blends, resulting in uniform dispersion of additives and fillers and improved mechanical properties in finished products.

Synergistic Effects: DBLS often functions synergistically with other heat stabilizers, antioxidants, and lubricants in polymer formulations, enhancing overall performance and cost-effectiveness while reducing the need for higher loading levels of individual additives.

Compatibility: Dibasic Lead Stearate exhibits excellent compatibility with PVC resins and other polymer matrices, ensuring uniform distribution and effective dispersion throughout the polymer matrix, thereby maximizing its stabilizing and lubricating effects.

Applications:

PVC Processing: Dibasic Lead Stearate is widely used as a heat stabilizer and lubricant in the processing of PVC products, including rigid PVC pipes, profiles, cables, sheets, and films. It improves melt flow properties, reduces melt viscosity, and prevents thermal degradation during extrusion, injection molding, and calendaring operations.

Rubber Compounding: DBLS is employed as a lubricant and processing aid in the compounding of rubber formulations, including natural rubber (NR), synthetic rubbers (SBR, NBR, EPDM), and thermoplastic elastomers (TPEs). It facilitates mixing, reduces friction, and enhances dispersion of fillers and additives, resulting in improved processing and mechanical properties in rubber products.

Other Applications: Dibasic Lead Stearate finds applications in various other industries, including coatings, adhesives, lubricants, and cosmetics, where its heat stabilization, lubrication, and compatibility properties are beneficial.

Safety Considerations:

Proper handling and storage procedures should be followed when working with Dibasic Lead Stearate to minimize exposure and ensure worker safety.

Personal protective equipment (PPE), including gloves, goggles, and protective clothing, should be worn during handling and processing of DBLS.

Adequate ventilation should be provided in processing areas to prevent inhalation of fumes or dust particles.

Spills or leaks of Dibasic Lead Stearate should be promptly cleaned up and disposed of according to local regulations and guidelines.

Dibasic Lead Stearate (DBLS) is a versatile additive that provides heat stabilization, lubrication, and processing benefits in PVC and rubber formulations, contributing to improved product quality, processing efficiency, and performance in various industrial applications. Trust in the reliability and effectiveness of DBLS to enhance the properties and processing characteristics of your polymer products.
