What is Calcium Stearate?

Calcium stearate is additionally referred to as calcium octadecate. White light crystalline powder. Chemical formula (C17H35COO)2Ca. Molecular weight 607.00. Melting point 179 ~ 180 ℃, broken down by high heat. Insoluble in water, cool ethanol as well as ether, soluble in hot benzene, toluene and also turpentine, somewhat soluble in warm ethanol as well as ether. It is disintegrated right into stearic acid as well as the corresponding calcium salt with strong acid. Absorbs water in the air. Not resistant to lipolytic microbes. Pyrolysis creates stearyl ketone and hydrocarbons. Safe. Matching oleates are commonly combined in industrial products. Utilized as stabilizer and lubricating substance for polyvinyl chloride; as halogen absorber in polyethylene as well as polypropylene; lube for polyolefin fibers as well as molded products; lubricating substance and also release agent for phenolic, amino and various other thermosetting plastics; lubrication Thickening representative for grease; waterproofing representative for waterproof fabrics; squashing agent for paint and also lubricant for pencil lead, and so on. Food quality calcium stearate is utilized as an anticaking representative. Thinned down soap remedy is prepared by reacting stearic acid which is baked as well as melted with sodium hydroxide, and after that reacted with calcium chloride.

This product can be made use of as a heat stabilizer for polyvinyl chloride and also has excellent lubricity. The thermal stability is ordinary, not as good as barium stearate, lead stearate, tin stearate and cadmium stearate. Yet it is cheap as well as very easy to acquire, with low poisoning and excellent processability. It has a synergistic effect when made use of in mix with zinc soap as well as epoxy substances, as well as can improve thermal security. Incorporated with fundamental lead salt and also lead soap in tough products, it can boost the gelation speed. Calcium stearate is used in polyethylene as well as polypropylene to get rid of the damaging impacts of recurring stimulant on material color and also stability. This product is also extensively used as a lubricant as well as launch agent for thermosetting plastics such as polyolefins, polyester strengthened plastics, phenolic materials, amino resins, etc. The disadvantage of calcium stearate is that it has initial tinting properties. When the home heating time is above 100 ° C for a very long time, the white PVC plastic will turn red, especially when there is titanium dioxide in the formula, the coloring is especially serious. Currently, if 0.06-0.12% Na2CO3 or 0.09-0.19 NaHCO3 is added, this shortcoming can be gotten over, but due to the fact that these materials are also alkaline, they are not used in practice. Additionally, when the amount of this item is large, there is a sensation of partition and scaling.

Calcium Stearate Uses

  1. Calcium stearate is made use of as a non-toxic stabilizer, lube, mold launch agent and also textile waterproofing representative for PVC plastics.
  2. Calcium stearate is utilized as a lubricating substance for finish as well as processing paper and also paint.
  3. Calcium stearate is made use of as an anticaking representative; a binder; an emulsifier; a lubricant; a release representative; a stabilizer; a thickening representative; a flavoring agent.
  4. Calcium stearate is used as a stabilizer and lubricating substance for polyvinyl chloride, and can be used as non-toxic food product packaging, clinical tools as well as various other soft film utensils. As a halogen absorber in polyethylene as well as polypropylene, it can get rid of the recurring stimulant in the resin as a lubricant for material color as well as shaped products, as well as can also be used as a lubricant for phenolic, amino and various other thermosetting plastics and also polyester strengthened plastics. agent, enlarging representative for grease, waterproofing representative for fabrics and also flattening representative for paint, etc. Food quality calcium stearate works as an anticaking representative to avoid powdered or crystalline food from clumping as well as clumping to maintain it free-flowing. However, the only anti-caking representative allowed my nation’s GB2760-86 is presently potassium ferrocyanide, which is used for common salt. According to FAO/WHO regulations, calcium stearate can be utilized for layer glucose powder, sucrose powder and also soup dices, and so on, the optimum allowed dosage is 15 g/kg.
  5. Calcium stearate is utilized as water repellent, lube as well as plastic help. Extensively used in food, medication, cosmetics, plastic rubber and various other industries, mostly as lubricants, emulsifiers, stabilizers, launch agents, accelerators, aesthetic base products, and so on. In stiff plastic products, the establishing speed can be enhanced. It can likewise be used for non-toxic soft movies such as food product packaging and also medical equipment, and also has the result of stabilizer, with good long-term security. It can be used as stabilizer and lubricant in polyethylene and also polyvinyl chloride, and as halogen absorber in polyethylene and also polypropylene, it can get rid of the adverse impacts of the driver continuing to be in the resin on the color as well as security of the resin. It is extensively used in foreign countries to enhance the warm resistance of plastics, boost the initial coloring and also air leaks in the structure of weather condition resistance, and will replace the toxic stabilizers with the very same properties.

Application of Calcium Stearate in PVC Formulation

Calcium stearate is utilized as a warmth stabilizer for PVC as well as a lubricating substance and mold release agent for different plastics handling. When utilized as a PVC lube, it is generally considered an internal lubricant. Calcium stearate is the stearate of medium and also solid alkali calcium, which has strong polarity. The chemically energetic factor of PVC resin fragments can develop a relatively steady complicated system with calcium stearate. Both long-chain alkyl groups of calcium stearate have little compatibility with polar resins such as PVC, as well as create a local microscopic two-phase user interface inside the PVC material, that is, a lubricating film. The microscopic significance of its lubricating effect is that the force between the local lubricating interface formed by the non-polar long-chain alkyl team as well as the polar material sector is smaller sized than that between the resin sectors, and also due to the fact that there are numerous little pores between the material sectors, As a result, when the material segment is displaced, the randomly deformable alkyl team is pressed right into various other adjacent pores, therefore reducing the resistance of the resin sector throughout displacement and also functioning as internal lubrication.

In sensible application, calcium stearate as a PVC lube does not just play an internal lubricating role, its lubricating role is much more complicated, and in various other instances where the percentage of internal lubrication is fairly high, it will mirror the function of external lubrication. Additionally, it has a synergistic impact with several lubricating substances.

Making use of calcium stearate alone in the formula can speed up plasticization, rise melt thickness, boost torque, as well as have a certain demoulding impact, while making use of paraffin alone can delay plasticization, reduce torque, and have no demoulding effect. When calcium stearate and also paraffin wax (polyethylene wax) are mixed in a particular percentage, it reveals a great impact, and the torque value of the material can be greatly decreased. This is due to the fact that the paraffin penetrates right into the molecules of calcium stearate as well as strengthens the lubricating effect., showing a strong synergistic effect, transforming the diffusion of lubes.

Calcium stearate, originally used in PVC as an auxiliary stabilizer, is mainly used to absorb chloride ions generated by PVC degradation; at the same time, you should also find that calcium stearate is also very useful in polyolefin formulations. Generally, not many people may know the purpose of using calcium stearate in the original design of polyolefin formulations. In fact, calcium stearate was originally used in polyolefin formulations to absorb some halogen components added during polyolefin polymerization, so There is a name called halogen absorber.

Calcium Stearate Identification Test

Take 1 g of the sample, mix it with 25 ml of water and 5 ml of hydrochloric acid, and heat it to release the fatty acid, so that the oily layer floats on the liquid surface. Calcium test (IT-10) with water layer should be positive.
Take 25g of sample, mix it with 200ml of hot water, add 60ml of dilute sulfuric acid test solution (TS-241), heat and stir vigorously until the fatty acid is precipitated and becomes a transparent clear liquid. Wash the fatty acid with boiling water until the sulfate is removed, collect it in a small beaker, and warm it on a steam bath until the fatty acid and the water layer are completely separated and transparent. After cooling, the water layer was discarded, and the fatty acid was melted and filtered into a drying beaker, and dried at 105° C. for 20 min. The freezing point of the refined fatty acid should not be lower than 54°C. The freezing point is determined by conventional methods.
