Calcium Stearate Powder

Technical Parameter of Calcium Stearate Powder:

Calcium Stearate Uses:

Plastics industry: Calcium stearate is used as a plasticizer and stabilizer in the plastics industry, helping to improve the flexibility and durability of plastics. It can reduce the coefficient of friction on the surface of plastics and improve the lubricating performance of plastics, and at the same time, it can inhibit the aging of plastics and prolong the service life of plastic products. In addition, calcium stearate can also be used as a processing aid to improve the processing performance of plastics.

Rubber industry: Calcium stearate is used as vulcanizing agent and lubricant in the rubber industry. It can increase the hardness and elasticity of rubber and help to improve the processing performance of rubber. At the same time, calcium stearate can also improve the anti-aging properties of rubber products and extend their service life. It can be used as a raw material for rubber and polyurethane shoe soles to increase the hardness and abrasion resistance of shoe soles.

Cosmetics and skin care products: Calcium stearate is also used in cosmetics and skin care products as an emollient and moisturizer. It can form a film to lock in moisture and keep the skin smooth and delicate. In addition, calcium stearate improves product stability and prevents ingredients in the product from settling or separating.

Paints and Coatings: Calcium Stearate is used as a thickener and pigment dispersant in paints and coatings. It improves the viscosity and hiding power of coatings and helps the pigments to disperse evenly in the coatings. In addition, calcium stearate improves the weathering and water resistance of paints, making them more durable.

Pharmaceutical field: Calcium stearate also has some applications in the pharmaceutical field. It can be used as a drug carrier to help the drug penetrate better into the skin or mucous membranes and improve the efficacy of the drug. In addition, calcium stearate can also be used as a drug protection agent to reduce the irritation and side effects of drugs on the human body.

Agriculture: Calcium stearate can be used as fertilizer synergist and pesticide carrier in agriculture. It can improve the utilization rate of fertilizers and promote the absorption of nutrients by plants, and it can also help pesticides better adhere to the surface of plants and improve the prevention and control effect of pesticides.

Petrochemical field: Calcium stearate can be used as lubricant and additive in petrochemical field to improve the quality and performance of petroleum products. In addition, calcium stearate can be used as a raw material for the production of spices, used in the preparation of various flavors and fragrances.

Food industry: Calcium stearate can be used as emulsifier and stabilizer in the food industry to improve the taste and stability of food. For example, it can be used to make dairy products such as ice cream and cheese to improve their texture and taste. In addition, calcium stearate can be used as a moisture barrier and lubricant for food packaging materials.

Surfactant: Calcium stearate can be used as a surfactant to help detergents and other laundry products better clean a variety of surfaces. It has good detergency and penetrating ability to effectively remove dirt and grease. In addition, calcium stearate can be used as a foam stabilizer and thickener for detergents.

Environmental protection field: Calcium stearate also has some applications in the environmental protection field. It can be used to prepare biodegradable plastics and reduce white pollution. In addition, calcium stearate can be used as a lubricant and fuel additive to reduce mechanical wear and energy consumption.

Is calcium stearate safe to eat?
Calcium stearate has almost no side effects as a food additive. It is generally considered to be safe (GRAS) in food, and there are no other restrictions except for the current good production practices of FDA. It can be used as flavoring agent and auxiliary agent, lubricant and release agent, stabilizer and thickener.

Is calcium stearate vegan?
Yes, most used calcium stearate today in food products is vegetable calcium stearate.  It is considered vegan because the manufacturing process does not use animal substances or products of animal origin.
But stearic acid can also be produced from animal fats and oils, so vegetarians should avoid this source.

Q: How does calcium stearate powder affect the performance of plastic products?
A: Calcium stearate powder can significantly improve several aspects of a product during plastics processing: Enhanced flow: Reducing the friction between resins makes it easier for plastics in the molten state to flow, thus improving molding speed and quality. Improve surface finish: Due to its lubricating effect, it can make the surface of the finished product smoother and more delicate, reducing defects. Prevents sticking to the mold: effectively avoids the adhesion of plastic parts on the inner wall of the mold, simplifies the demolding process and reduces the scrap rate. Stabilizes color and form: Helps maintain the color stability of the plastic, especially at high temperatures; it also keeps the shape intact and is not easy to deform. Environmentally friendly: Compared to some organic lubricants, calcium stearate is more environmentally friendly and does not emit harmful fumes or residues.
 
Q: What should I pay attention to when using calcium stearate powder?
A: To ensure safe and effective use of calcium stearate powder, users should pay attention to the following points: Protective measures: Appropriate personal protective equipment (e.g., gloves, masks) should be worn when handling calcium stearate to avoid direct contact with skin or inhalation of dust.
Storage conditions: Store in a dry, cool place, away from fire and strong oxidizers to prevent accidents. Mixing Ratio: Add calcium stearate in strict accordance with the recommended ratio, too much may cause the plastic to be too soft or affect the effect of other additives. Homogeneous Dispersion: Ensure that the calcium stearate is well mixed in the raw material to avoid localized high concentration which may cause adverse effects. Compatibility assessment: Check the compatibility between calcium stearate and other ingredients, especially for complex formulation systems, to ensure that it will not cause incompatibility problems.
 
Q: What are the environmental and health effects of calcium stearate powder?
A: Regarding the potential environmental and health impacts of calcium stearate, current research suggests the following: Low toxicity: Calcium stearate itself is a low-toxicity substance and is not normally harmful to humans, but caution is still needed in cases of inhalation of large quantities or prolonged exposure. Low ecological risk: Although it may have some impact on aquatic organisms when it enters water bodies, its impact on the ecosystem is relatively low because it is easily decomposed naturally. Waste disposal: Waste calcium stearate and its packaging materials should be disposed of properly in accordance with local regulations and should not be thrown away to avoid polluting the environment. Occupational health: In industrial environments, effective ventilation measures should be taken and air quality should be monitored regularly to protect the occupational health of employees.
 
Q: How to choose the right type and supplier of calcium stearate powder for a specific application?
A: Selecting the calcium stearate powder type and reliable supplier that best suits the project needs is a critical step in ensuring product quality and cost-effectiveness: Define the requirements: First determine the requirements of the specific application, such as the desired lubrication effect, applicable temperature range, color stability, etc. Comparison of technical parameters: Compare the technical specifications of different models, such as purity, particle size distribution, melting point, etc., and select the product that best meets the project requirements. Sample testing: Request samples from potential suppliers and conduct preliminary tests in the laboratory or small-scale trials to assess whether their actual performance meets expectations. Supplier reputation: Examine the supplier's historical performance, customer evaluations and level of technical support, and prioritize those with extensive experience and a good reputation. Price and supply stability: Consider the market price of the product, the volume discount policy and the reliability of long-term supply to find the most cost-effective partner. Certification and Compliance: Ensure that the selected products comply with relevant international standards and regulatory requirements, such as REACH, RoHS, etc., in order to cope with the increasingly stringent market access conditions.
