Applications

Zinc stearate finds applications in numerous industries due to its versatile properties:

Plastics and Rubber Industry

Lubrication and Processing Aid: In plastics and rubber, zinc stearate acts as a lubricant, reducing friction during processing. For instance, in PVC production, zinc stearate helps maintain material consistency and flow.
Heat Stabilizer: Zinc stearate serves as a heat stabilizer, preventing the thermal degradation of PVC during processing.

Textile Industry

Polishing Agent: Zinc stearate is a crucial polishing agent in textiles, giving fabrics a smooth, glossy finish.

Paints and Enamels

Matting Agent: In paints and enamels, zinc stearate acts as a matting agent, achieving a uniform, matte finish.

Packaging and Storage

Packaging Options: Typically packed in 20 kg bags, 400 kg ton bags for powder, and 25 kg bags for granules. Custom packaging solutions can meet specific requirements.
Storage Conditions: Stored in a cool, dry place, away from sunlight and moisture, to prevent caking and ensure it remains free-flowing and easy to use.
