Description

Zinc Adipate is a white, crystalline salt of adipic acid and zinc, widely recognized for its utility as a heat stabilizer and lubricant in polymer formulations. Its primary commercial value lies in its ability to enhance the thermal stability and processing characteristics of various plastics, particularly polyvinyl chloride (PVC), without compromising clarity or performance. This compound is essential for manufacturers in the plastics, polymer additives, and specialty chemical industries seeking to improve product longevity and processing efficiency.

Application

• Primary Heat Stabilizer for PVC: Used in rigid and flexible PVC formulations, including pipes, profiles, cables, and films, to prevent thermal degradation during processing and extend service life.
• Lubricant and Processing Aid: Acts as an internal/external lubricant in polymer processing, improving flow properties and reducing sticking to metal surfaces.
• Synergistic Co-stabilizer: Often used in combination with other metal soaps (e.g., calcium/zinc systems) to enhance overall stabilization performance, especially in applications requiring low toxicity.
• Catalyst and Curing Agent: Employed as a catalyst in certain polyester resin systems and as a curing agent for epoxy resins.
• Additive for Engineering Plastics: Imparts improved thermal and light stability to other engineering polymers beyond PVC.
• Corrosion Inhibitor Precursor: Serves as a source of zinc in the formulation of corrosion-inhibiting pigments for coatings.

Quality Control

Our Zinc Adipate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high performance. We provide material that meets typical industrial-grade specifications, with key parameters including zinc content, adipic acid content, moisture, and particle size distribution. A Certificate of Analysis (COA) detailing purity, assay, and relevant physical-chemical properties is available for every shipment upon request, ensuring full traceability and compliance with your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to minimize exposure to atmospheric humidity, which can lead to caking or reduced efficacy.
