Tribasic Lead Stearate (TBLS)

Product Description: Tribasic Lead Stearate (TBLS)

Tribasic Lead Stearate (TBLS) is a versatile chemical compound widely used as a heat stabilizer and lubricant in the processing of polyvinyl chloride (PVC) and other polymer-based materials. With its unique properties, TBLS offers excellent thermal stability, lubrication, and processing benefits, making it an essential additive in polymer formulations for various industrial applications.

Key Features:

Heat Stabilization: TBLS acts as an effective heat stabilizer, preventing thermal degradation of polymers during processing and prolonged exposure to elevated temperatures. It inhibits the formation of hydroperoxides and other reactive species, thereby preserving the mechanical and physical properties of the polymer.

Lubrication: TBLS 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: Tribasic 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: TBLS 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: Tribasic 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: TBLS 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: Tribasic Lead Stearate 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: TBLS 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 Tribasic 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 TBLS.

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

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

Tribasic Lead Stearate (TBLS) offers reliable heat stabilization and lubrication benefits in PVC and other polymer formulations, contributing to improved processing efficiency and product quality in various industrial applications. Trust in the performance and versatility of TBLS to enhance the properties and processing characteristics of your polymer products.
