Description

Strontium Dioleate is a metal soap derived from strontium and oleic acid, functioning as a versatile organometallic compound. This product is valued for its role as a heat stabilizer and lubricant, particularly in polymer processing where it enhances thermal stability and processing characteristics. It serves as a critical additive for industries involved in PVC manufacturing, lubricant formulation, and the production of specialized greases and coatings, addressing key needs for performance and longevity in finished products.

Application

• PVC Heat Stabilizer: A primary component in mixed-metal stabilizer systems for rigid and flexible PVC, effectively scavenging hydrochloric acid generated during thermal processing to prevent polymer degradation.
• Polymer Processing Aid & Lubricant: Acts as an internal and external lubricant in various polymer compounds, improving flow properties, reducing melt viscosity, and preventing sticking to processing equipment.
• Grease Thickener & Modifier: Used in the formulation of complex soap-based greases, contributing to texture, water resistance, and thermal stability.
• Paint & Coating Drier: Functions as a secondary drier (through-stratifier) in oil-based paints and coatings, promoting uniform drying through the film layer.
• Waterproofing Agent: Imparts hydrophobic properties to textiles, papers, and construction materials.
• Catalyst & Reaction Intermediate: Serves as a catalyst or precursor in various organic synthesis and cross-linking reactions.

Quality Control

Our Strontium Dioleate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for metal content, acid value, moisture, and other critical parameters. Certificates of Analysis (COA) are provided with every shipment to guarantee traceability, consistency, and compliance with agreed-upon standards.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to minimize exposure to atmospheric humidity.
