Industrial Uses

1. Performance Chemicals

  • Catalyst in Polymerization: Acts as a heat stabilizer and catalyst in the production of polyvinyl chloride (PVC) and other polymers.
  • Intermediate: Used in synthesis processes where metallic soaps are needed to modify physical properties of materials.

2. Construction

  • PVC Pipes & Profiles: Employed as a heat stabilizer in PVC compounds used for window profiles, electrical conduits, and pipes.
  • Thermal Stabilization: Enhances resistance to heat degradation during the processing of construction-grade plastics.

3. Paints, Coating & Adhesives

  • Lubricating Agent: Acts as a lubricant and stabilizer in sealant formulations, particularly in PVC-based or rubber-based sealants.
  • Processing Aid: Facilitates smooth blending and dispersion of other additives in adhesive formulations.

4. Polymers & Resins

  • Heat Stabilizer in PVC: One of the traditional stabilizers for rigid PVC products, such as cable insulation, pipes, and window profiles.
  • Lubricant: Functions as an internal and external lubricant in plastic compounding processes.
