Zinc Stearate

Product Advantage

Enhanced Product Performance: Through specialized wet or dry processes, our zinc stearate improves heat resistance, lubricity, and demolding properties of plastic, rubber, and coating products—directly boosting production efficiency for manufacturing enterprises.

Strict Quality Assurance: From raw material procurement to finished product delivery, every step undergoes rigorous inspection, ensuring consistent zinc content (10.3%-11.3%) and low impurity levels, meeting the high standards of chemical buyers.

Advanced Production Technology: Our unique double decomposition process reduces free acid and moisture content, resulting in stable performance in high-temperature industrial processes like plastic extrusion and rubber vulcanization.

Tailored Solutions: Offers customized specifications (e.g., fineness, zinc content, and packaging) for diverse applications—from PVC heat stabilizer for plastic pipes to rubber vulcanization activator for tires.

Fast Global Delivery: Equipped with an efficient logistics system, we ensure timely shipment of bulk zinc stearate to clients worldwide, supporting just-in-time production for plastic, rubber, and coating manufacturers.

Our zinc stearate adheres to industrial standards (HG/T3667-2012) with technical parameters optimized for applications like plastic processing and rubber manufacturing:

Product Uses

Plastic Industry: Serves as a top-tier PVC heat stabilizer, lubricant, and release agent for PVC, PS, and other plastics. Improves melt flow, surface smoothness, and demolding efficiency, widely used in plastic pipe manufacturers, sheet production, and injection-molded parts.

Rubber Industry: Acts as a vulcanization activator and plasticizer, promoting vulcanization and reducing compound friction. Enhances elasticity and tensile strength of tires, seals, and rubber hoses—ideal for tire manufacturers and rubber product enterprises.

Coated Abrasives: Functions as a coating additive for sandpaper and grinding tools, improving adhesion between abrasives and substrates. Enhances abrasion resistance and antistatic properties, prolonging tool lifespan for abrasive manufacturers.

Paper Industry: Used as a waterproofing agent and lubricant in coated paper, packaging paper, and specialty papers. Improves water resistance, surface smoothness, and printability, supporting paper manufacturers in upgrading product quality.

Paint & Coatings Industry: Serves as a drier, lubricant, and anti-sedimentation agent in industrial coatings, wood paints, and architectural coatings. Accelerates film drying, prevents pigment settling, and enhances leveling—trusted by coating manufacturers worldwide.

FAQ

Q: Is your zinc stearate non-toxic for industrial and consumer-related applications?

A: Yes, our product is non-toxic and non-hazardous, complying with global safety standards for plastic additives, rubber processing, and coatings—safe for use in consumer-facing products and industrial environments.

Q: What is the difference between wet process and dry process zinc stearate?

A: Wet process has a higher heating decrement (≤1.0%) and is ideal for plastic processing, while dry process (heating decrement ≤0.2%) performs better in high-temperature applications like rubber vulcanization. Our team can recommend the right grade for your needs.

Q: Can you provide customized packaging for bulk industrial orders?

A: Yes, we offer flexible packaging options, including 25kg bags, 1mt bulk bags, or even customized labels for chemical suppliers. Contact us to discuss quantity and logistics requirements.

Q: How should zinc stearate be stored to maintain its performance?

A: Store in a dry, ventilated, low-temperature area, away from heat sources and direct sunlight. Seal the container tightly to prevent moisture absorption—ensuring stability for industrial inventory management.
