Stearic Acid 1838 Lubricant High-Performance Lubrication

Features

Excellent lubrication performance: Stearic acid 1838 molecules have a long carbon chain structure. During the lubrication process, they can form a uniform and tough lubricating film on the surface of the object.

This lubricating film can significantly reduce the friction coefficient and reduce the wear between moving parts. It can effectively play a lubricating role and extend the service life of the equipment regardless of high load or high-speed operation. For example, in metal processing, it can make the cutting process smoother and reduce the wear of the tool.

Good thermal stability: Under high temperature environment, stearic acid 1838 has good thermal stability and is not easy to decompose or volatilize.

Generally, it can maintain stable lubrication performance within the temperature range of 150℃ - 200℃, which makes it suitable for some processing processes with high temperature requirements, such as high-temperature extrusion molding of plastics, to ensure the durability of the lubrication effect during the processing.

Strong compatibility with a variety of materials: It can be well compatible with a variety of materials, including various types of plastics (such as polyethylene, polypropylene, polyvinyl chloride, etc.), rubber and metal.

In plastic processing, it can be evenly dispersed in the plastic matrix without affecting the basic properties of the plastic, while improving its processing performance; in metal processing, it can closely bond with the metal surface to form effective lubrication protection.

High chemical stability: Stearic acid 1838 has a certain chemical stability and is not easy to react with other chemicals. Under normal use and storage conditions, it can maintain its own chemical properties and will not deteriorate quickly due to contact with oxygen, moisture, etc. in the air, thus ensuring the reliability of its lubrication performance.

Application areas

Plastic processing industry: As an important lubricant in plastic processing, stearic acid 1838 can improve the fluidity of plastic melt, reduce its viscosity, and make plastic easier to shape. In injection molding, blow molding, extrusion and other processes, it can reduce the friction between plastic and processing equipment, prevent plastic from sticking to the mold, and improve the surface quality and production efficiency of plastic products.

For example, when producing plastic pipes, adding stearic acid 1838 can make the pipe surface smoother and the dimensional accuracy higher.

Rubber processing industry: Stearic acid 1838 can be used as a softener and lubricant during rubber mixing. It can reduce the hardness of rubber, increase the plasticity and flexibility of rubber, and make rubber easier to mix, calender and mold. At the same time, it can also improve the demoulding performance of rubber products, reduce the adhesion between rubber products and molds, and improve the qualified rate of products.

Metal processing industry: It can be used as a lubricant and rust inhibitor in metal cutting, stamping, rolling and other processing processes. It can form a protective film on the metal surface, reduce the friction and wear between the metal and the tool and mold, improve the processing accuracy and surface quality, and has a certain anti-rust ability to protect the metal surface from oxidation corrosion.

Other fields: In the coating, ink and other industries, stearic acid 1838 can also be used as an additive to improve the leveling, dispersibility and wear resistance of coatings and inks, and improve the quality and performance of products.

Precautions

Storage conditions: It should be stored in a cool, dry and well-ventilated warehouse to avoid moisture and direct sunlight.

Stearic acid 1838 is highly hygroscopic, and moisture may affect its lubrication performance and compatibility with other materials. At the same time, keep away from fire and heat sources to prevent fire or product deterioration due to high temperature.

Safety of use: Although stearic acid 1838 is generally considered to be low-toxic, it is still necessary to pay attention to protection during operation.

Avoid direct contact with skin and eyes. If accidentally contacted, rinse with plenty of water immediately and seek medical attention in time. It is recommended to wear personal protective equipment such as protective gloves, masks and goggles during operation to ensure safety.

Amount control: When using stearic acid 1838, the amount of addition needs to be strictly controlled. Too little addition may not achieve the ideal lubrication effect, while too much addition may have a negative impact on the performance of the product, such as reducing the mechanical properties of plastic products.

The specific amount of addition should be adjusted according to different application areas and product requirements, usually between 0.5% - 2%.

In combination with other additives: In practical applications, stearic acid 1838 is often used in combination with other additives (such as stabilizers, plasticizers, antioxidants, etc.).

Attention should be paid to the interaction between these additives to avoid adverse reactions that affect the performance and quality of the product. Before use, it is best to conduct sufficient tests and evaluations to determine the best additive formula.
