The product is Factory Supply Calcium Stearate with CAS 1592 - 23 - 0 and comes with the best price. Calcium stearate is a carboxylate of calcium, classified as a metal soap. It is a waxy white solid. Chemically, it is the double salt of stearic acid (CH₃(CH₂)₁₆COOH) and a small amount of palmitic acid (CH₃(CH₂)₁₄COOH) with calcium ions. The molecular formula is C₃₆H₇₀CaO₄.
It has a melting point in the range of 147 - 149 °C. In terms of solubility, it is poorly soluble in water, alcohol, and ether. It has a density of approximately 1.08 g/cm³. The product is usually available in powder form, and the particle size can be customized according to different requirements, commonly in the range of 10 - 80 mesh.
Calcium stearate has a wide range of applications in various industries. In the plastics industry, it is widely used as a lubricant, releasing agent, and acid scavenger. It can improve the flow characteristics of plastic materials during processing, prevent the adhesion of plastics to molds, and also neutralize acidic substances that may be generated during the processing of PVC and other plastics, thereby improving the stability and quality of plastic products.
In the rubber industry, it serves as an activator and softener. It can enhance the dispersion of fillers in rubber compounds, improve the physical properties of vulcanized rubber, such as tensile strength and elongation at break, and also reduce the viscosity of rubber compounds, making the processing easier.
In the paint and coating industry, it acts as a flatting agent and anti - settling agent. It can make the coating surface have a matte effect, and prevent the sedimentation of pigments and fillers in the coating, ensuring the uniformity and stability of the coating.
When using calcium stearate in the plastics industry, it can be added directly to the plastic resin during the mixing process. The recommended addition amount is usually 0.2% - 1.0% by weight, depending on the type of plastic and the specific processing requirements. For example, when processing PVC, a relatively higher addition amount may be required to achieve better lubrication and heat - stability effects.
In the rubber industry, it is added during the rubber mixing process. It should be uniformly dispersed in the rubber compound to ensure its full effect. The addition amount is generally 0.5% - 3% by weight.
In the paint and coating industry, it can be added during the preparation of the coating. It is usually dispersed in the coating system under high - speed stirring to ensure its uniform distribution. The addition amount is typically 0.1% - 1.5% by weight, depending on the desired flatting effect and anti - settling performance.
A plastic product manufacturing company was facing problems with poor mold release and rough surface finish in their injection - molded PVC products. After adding Factory Supply Calcium Stearate with a proper addition amount of 0.8% by weight, the mold release became much easier, and the surface of the products became smoother. The production efficiency increased by 20% due to reduced cleaning time of the molds, and the defective rate decreased from 5% to 1%.
A rubber tire manufacturer was struggling with the dispersion of carbon black in their rubber compounds, which led to inconsistent physical properties of the tires. By adding 1.5% calcium stearate during the mixing process, the carbon black was more uniformly dispersed. As a result, the tensile strength of the tires increased by 15%, and the wear resistance improved significantly, which extended the service life of the tires.
A paint factory wanted to produce a matte paint with good anti - settling performance. They added 0.5% calcium stearate to their coating formula. The resulting paint had a beautiful matte finish, and there was no obvious sedimentation after long - term storage, which met the market requirements and increased the market competitiveness of their products.
