Calcium Stearate

Product Advantage

Performance Enhancement: Through special processing technology, our industrial grade Calcium Stearate effectively improves product adhesion, lubricity, and thermal stability, directly boosting the quality and durability of end products for customers.

Strict Quality Control: From raw material procurement to finished product delivery, each batch undergoes rigorous inspection, ensuring consistent calcium content (6.5±0.5%) and low impurity levels, meeting the high standards of plastic and rubber manufacturers.

Advanced Production Process: Our unique synthesis method reduces heating decrement (≤3.0%) and enhances fineness (≥99.5% passing 0.075mm sieve), ensuring excellent dispersion and compatibility in various industrial applications.

Customized Services: We offer tailored specifications, including calcium content adjustment, particle size optimization, and packaging customization (e.g., 20kg/bag, bulk bags), to meet diverse application scenarios of industrial clients.

Efficient Bulk Delivery: Our global logistics network supports fast delivery of large orders, ensuring timely supply for industrial production lines, with flexible shipping terms (FOB, CIF) for overseas customers.

Calcium Stearate meets industrial use requirements with the following key parameters:

Product Uses

Coated Sand for Casting: As a critical additive in coated sand production, it improves adhesion between resin and sand grains, enhancing mold strength and demoldability. Widely used by casting enterprises for manufacturing cores for machinery parts and automotive components.

Plastic CPE Processing: Serves as a lubricant and heat stabilizer in chlorinated polyethylene (CPE) and related plastic processing, improving processing fluidity and surface smoothness. Suitable for plastic manufacturers producing industrial pipes, sheets, and modified plastics, enhancing weather resistance.

PVC Heat Stabilizers: Acts as an auxiliary heat stabilizer for PVC products, working with zinc soaps to neutralize hydrogen chloride from degradation. Ideal for PVC manufacturers producing construction profiles, packaging materials, and electrical insulation products, extending thermal stability.

Rubber Industry: Functions as a vulcanization activator and lubricant, promoting rubber vulcanization, reducing processing friction, and improving elasticity and anti-aging properties. Used by rubber product suppliers for producing industrial seals, tires, and rubber hoses.

Building Materials Waterproofing: Serves as a waterproofing agent in mortar, concrete, and other building materials, reducing water absorption and enhancing water resistance. Suitable for construction material manufacturers producing moisture-proof coatings and waterproof membranes for industrial and civil buildings.

Food-Grade Plastic Auxiliary: Due to its non-toxic property, it is used as a lubricant in food-grade plastic processing (e.g., plastic containers, packaging films), complying with food safety standards for customers in the food packaging industry.

FAQ
