I would like to ask about the application of calcium stearate in the chemical industry (such as plastics and rubber). For example, it can be used for lubrication in phenolic resins. Which industry's phenolic products use calcium stearate? Thanks for the answer
Used as heat stabilizer for polyvinyl chloride and lubricant for various plastic processing, release agent, etc. In hard products, the gelation speed can be increased by combining with basic lead salt and lead soap. It is also used in soft films and appliances that require nontoxicity, such as food packaging and medical equipment. It can also be used as a halogen absorber for polyethylene and polypropylene to eliminate the negative effects of residual catalyst on color and stability. Used as a plasticizer in rubber processing, it can soften natural rubber and synthetic rubber without having almost any effect on vulcanization. It is also used as a lubricant for polyolefin fibers and molding compounds, a thickening agent for grease, a waterproofing agent for textiles, a flattening agent for paint, and a plasticizer in the manufacture of plastic records. It is also used in pencil lead production and the pharmaceutical and spice industries. Phenolic plastic products: Molded plastic products, laminated products, foam plastic products, fiber products, cast products and packaging materials. Among them, the first three most commonly used pure phenolic resins are rarely processed into products individually due to shortcomings such as brittleness and poor mechanical strength. Generally, phenolic plastics are modified by adding a large amount of fillers to the resin. Different fillers are used to obtain different excellent properties and are used in different fields. Calcium stearate is one of the factory products. It can be said that most of them are added, and of course some are added with other stearates.
It is used as a lubricant in PVC processing and also acts as a stabilizer.
Can be used as stabilizer in chlorinated polyethylene rubber
