Aluminium distearate

Buyers should prioritize the purity level (typically ≥98%), moisture content (usually <2%), and free fatty acid content. For specific applications like lubricants or plastics, the melting point (typically 145°C - 160°C) and metal content (Al percentage) are critical benchmarks for ensuring chemical stability and performance.

The fineness of the powder (measured in mesh size, e.g., 200-325 mesh) determines its dispersibility. For paints and coatings, a finer particle size is required to ensure a smooth finish and effective thickening, whereas for plastic processing, a standard mesh may suffice for lubrication and heat stabilization.

Suppliers must provide a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. If the product is intended for food-contact packaging or cosmetics, it must comply with FDA (US) or REACH (EU) regulations. Ensure the supplier follows ISO 9001 for quality management and ISO 14001 for environmental standards.

It is widely used as a thickening agent in greases and lubricants, a waterproofing agent in textiles and construction, and a flatting agent in paints. In the plastics industry, it serves as an effective internal lubricant and heat stabilizer for PVC and other polymers.

The primary risks include quality inconsistency between samples and bulk orders and moisture absorption during sea transit. To mitigate this, insist on vacuum-sealed or moisture-proof double-layer PE packaging and consider hiring a third-party inspector like SGS or Intertek to verify the chemical composition before shipment.

Focus on volume-based pricing tiers; for example, ordering in full container loads (FCL) can reduce unit costs by 10-15% compared to LCL. Additionally, negotiate payment terms such as 30% deposit and 70% against the Bill of Lading (B/L) to protect your cash flow and ensure the supplier meets the shipping deadline.

Although it is generally classified as a non-hazardous chemical, it is a fine powder that is combustible. Ensure the shipping documents clearly state it is 'Non-Hazardous' to avoid unnecessary customs delays, and request that the cargo be stored in a cool, dry, and well-ventilated area on the vessel, away from oxidizing agents.

Utilize the secured payment services provided by Made-in-China.com to ensure funds are only released upon proof of shipment. Always verify the supplier's Business License and Export Permit to ensure they are a legitimate manufacturer rather than an unlicensed middleman, which reduces the risk of legal complications.
