For procurement managers and R&D scientists in the chemical and plastics industries, sourcing reliable raw materials like Calcium Stearate is a critical step in ensuring product quality and manufacturing efficiency. This guide aims to provide valuable insights for buyers looking to purchase industrial-grade Calcium Stearate, particularly for its extensive use in PVC applications and as a component in waterproof home chemicals. As a prominent manufacturer and supplier based in China, we emphasize the importance of understanding product specifications and supplier credentials.

When evaluating Calcium Stearate, buyers should pay close attention to its physical and chemical properties. The common appearance is a fine white powder, and its chemical formula, Ca(C17H35COO)2, signifies its composition. Key technical specifications to inquire about from potential suppliers include metal oxide content (typically around 6.5%), heating loss (moisture content, ideally below 3.0%), free acid content (stearic acid, kept to a minimum, e.g., <=1.0%), specific gravity, melting point, and sieve fineness (ensuring a high percentage passes through a 0.075 mm sieve, often >=99.0%). These metrics directly impact the product's performance as a PVC stabilizer and lubricant.

For procurement professionals, selecting the right supplier is as important as selecting the right product. When considering purchasing Calcium Stearate from China, look for manufacturers and trading companies with a proven track record. Verification of business licenses, independent audits, and high ratings from previous buyers are strong indicators of reliability. Companies that have been Gold Members since 2014 and have participated in trade shows often demonstrate a commitment to transparency and market engagement. We encourage you to compare suppliers and inquire about their import/export rights and buyer repeat rates.

The price of Calcium Stearate can vary based on volume and supplier. It is advisable to request quotes for different quantities to understand the cost-effectiveness for your production scale. For instance, prices may differ significantly between purchasing 1-19,999 kg and larger orders of 20,000+ kg. Customization options should also be explored; many suppliers offer tailored product specifications to meet unique application needs, whether for enhanced PVC processing or specific formulations in waterproof home chemicals.
