The molecular formula of aluminum distearate is C₃₆H₇₁AlO₅ , appearing as a white powder. Its density reaches 1.045 g/cm³ , with a melting point of 165~175 °C Its unique feature lies in its combination of the coordination stability of aluminum ions and the lubricity of stearic acid chains, enabling it to deliver outstanding performance across a wide range of applications. In manufacturing, JiaDeLe employs… High-end The process is meticulously engineered to ensure product purity. 、 Heavy metal levels fully comply with safety standards, giving customers greater peace of mind.
Application scenarios
In the rubber and plastics industry, aluminum distearate is a versatile agent, serving as… PVC Non-toxic heat stabilizer, at temperatures up to 180℃ In high-temperature environments, it can effectively inhibit HCl Degradation extends the service life of the product. 20% The above is particularly suitable for products with extremely high safety requirements, such as food-grade cling film and injection-molded components for children’s toys. ；
In the field of architectural waterproofing, it is sufficient to add to the waterproof coating 0.5%-1% , it can form a dense hydrophobic film, reducing the water absorption of concrete. Effectively enhance Water resistance provides a reliable guarantee for the waterproofing performance of buildings.
In the cosmetics industry, as an oil-in-water emulsifier, it can stabilize emulsion systems for up to 6 Months, commonly found in cream‑based products such as sunscreen and hand cream, not only enhance product stability but also improve the smoothness of the skin feel, delivering a superior user experience.
(2) Zinc stearate: for rubber and plastic processing “ High-efficiency lubricant ”
Jiadele employs a melt‑process to produce zinc stearate, with a zinc content of 10.3 %-11. 3% Between, the melting point is 120℃±5℃ . In polystyrene, ABS In resin processing, it demonstrates exceptional performance. The long carbon chains in its molecular structure significantly reduce the melt viscosity of the resin, minimize mold friction, and increase the extrusion rate. Very big It enhances performance while also preventing surface scratches on the molded parts, making it particularly well-suited for injection molding of precision electronic components and providing robust support for the high‑precision manufacturing of electronic products.
Application scenarios
In the plastics processing industry, zinc stearate is used as a mold release agent for PE During film production, the amount of slip agent can be reduced, lowering the film’s surface friction coefficient to 0.2 Below, the resulting film is smoother and more uniform;
In the rubber products industry, it serves as a vulcanization activator, accelerating sulfur crosslinking, shortening vulcanization time, and enhancing tensile strength; it is commonly used in the manufacture of rubber components such as sealing rings and conveyor belts.
In the coatings and inks industry, it serves as a matting agent, enabling precise control of film gloss while enhancing pigment dispersion and preventing settling and layering, thereby elevating the quality of coatings and inks to a higher level.
(3) Barium stearate: for high-temperature applications “ Long-Lasting Guardian ”
The melting point of barium stearate is > 210 °C Among alkaline earth metal stearates, it exhibits the best long-term heat stability. Jia De Le Production barium stearate, with a barium content of 20% +0.4 % , and it is free from sulfide contamination. When used in conjunction with cadmium soaps and zinc soaps, it can enable… PVC The product is in 70℃ Stable under humid and hot conditions 5000 For more than an hour, it provides reliable stability assurance for the product’s long-term use.
Application Scene
In the field of high-temperature cables, barium stearate is used as a stabilizer for… PVC Insulating layer, capable of withstanding 150℃ The prolonged high-temperature exposure significantly reduces the risk of insulation failure due to aging, making it ideally suited for applications such as automotive wiring harnesses and industrial equipment cables that demand superior heat resistance and insulation performance.
In the field of transparent products, when compounded with lead-based stabilizers, it can enhance… PC The light transmittance of the sheet reaches 90% In addition, it simultaneously inhibits yellowing and is commonly used in products with stringent requirements for transmittance and stability, such as optical lenses and lamp shades.
In the field of mechanical lubrication, after being formulated into a high-temperature grease, it… 200℃ It maintains colloidal stability under operating conditions and, when used for lubricating bearings in metallurgical equipment or injection-molding machine screws, can… Effective Reduce wear and extend the service life of mechanical equipment.
