Stearic Acid 1842 Lubricant Premium Quality Lubricant for Polymers
Features
Excellent lubrication performance: Stearic acid 1842 molecules have a typical long-chain fatty acid structure, which enables them to effectively reduce the internal friction between molecules in the polymer system.
During the polymer processing process, it can form an isolation layer between polymer molecular chains, reduce the entanglement and interaction between molecular chains, thereby significantly improving the fluidity of the polymer melt, reducing energy consumption during processing, and improving production efficiency.
For example, in plastic extrusion processing, it can make the material pass through the screw and die more smoothly, reducing equipment wear.
Good thermal stability: Within the common polymer processing temperature range (such as 150℃ - 230℃), stearic acid 1842 has good thermal stability and is not easy to decompose or volatilize.
This means that it can continuously and stably play a lubricating role throughout the entire processing process, and will not lose its effect due to temperature increase, ensuring the stability of the processing process and the consistency of product quality.
Good compatibility with polymers: It is well compatible with a variety of polymers such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS) and engineering plastics.
It can be evenly dispersed in the polymer matrix to form a stable system, which will not have an adverse effect on the basic physical and chemical properties of the polymer, and at the same time enhance the processing performance of the polymer and the surface quality of the product.
Auxiliary demoulding function: Stearic acid 1842 also has a certain auxiliary demoulding effect in polymer processing. It can reduce the adhesion between the plastic product and the mold, make the product easier to remove from the mold, reduce deformation and breakage during demoulding, and improve the product's qualified rate and production efficiency.
Application field
Plastic industry: widely used in the production of various plastic products, such as injection molding, extrusion, blow molding and other processes.
In PVC products, it can be used as an internal lubricant to improve plasticization performance, improve the flexibility and surface finish of the product; in PE and PP products, it can improve melt fluidity, reduce surface defects, and improve the molding quality of the product.
At the same time, it is also suitable for the production of plastic films, sheets, pipes, etc., to enhance their processing performance and product quality.
Rubber industry: In the rubber processing process, stearic acid 1842 can be used as a softener and lubricant. It can reduce the viscosity of rubber, make the mixing process easier, and improve the plasticity and processing performance of rubber.
In addition, it can also improve the demoulding performance of rubber products, improve production efficiency, and promote the vulcanization process of rubber to a certain extent.
Other polymer-related fields: In products containing polymer components such as coatings and inks, stearic acid 1842 can also be used as an additive to improve the fluidity, leveling and coating properties of the products, and improve the printing effect and product quality.
Precautions
Addition amount control: Although stearic acid 1842 has many benefits for polymer processing, the addition amount needs to be strictly controlled.
Excessive addition may lead to a decrease in the mechanical properties of polymer products, such as reduced tensile strength and hardness, and may also affect the thermal stability and aging resistance of the products. The specific addition amount should be adjusted according to the type of polymer, processing technology and product requirements, and the general addition amount is between 0.1% and 1.5%.
Storage conditions: It should be stored in a cool, dry, well-ventilated environment, away from moisture and direct sunlight. Stearic acid 1842 is highly hygroscopic, and moisture may affect its lubrication properties and compatibility with polymers; long-term exposure to high temperatures and sunlight may cause it to oxidize and deteriorate, reducing product quality.
Interaction with other additives: In practical applications, stearic acid 1842 is usually used in combination with other additives such as stabilizers, plasticizers, antioxidants, etc.
Attention should be paid to the interaction between these additives. Some additives may react chemically with stearic acid 1842, affecting its lubrication effect or the function of other additives. Therefore, sufficient testing and evaluation should be carried out before use to determine the best additive formula.
Safety protection: When handling stearic acid 1842, appropriate protective equipment such as gloves, masks and goggles should be worn to avoid direct contact with skin and eyes. Although it is generally considered to be of low toxicity, long-term or large-scale contact may have certain effects on human health. Hands and exposed parts should be washed promptly after handling.
