Plastic Additives High Purity 100% Zinc Stearate CAS 557-05-1

Zinc Stearate is a white powder that is insoluble in water. It is mainly used as a lubricant and release agent for styrene resins, phenolic resins, and amino resins, and can also be used in cosmetics, plastic stabilizers, and other fields.

(1) In the plastic industry: It is used as a lubricant to reduce the melt viscosity during plastic processing, improve fluidity, make the surface of products smoother, and reduce surface defects. It is an effective release agent that helps plastic products be easily removed from the mold, improving production efficiency and product quality and reducing the rejection rate.

(2) In the rubber industry: It is used as a vulcanization activator to accelerate the vulcanization speed of rubber, increase the cross-linking density and mechanical properties of the vulcanizate. It plays a role in softening and plasticizing, improving the processing performance and flexibility of rubber, making it easier to form rubber products.

In the coating and ink industry: In coatings, it can improve the water resistance and corrosion resistance of coatings, and also improve the fluidity and gloss of coatings. In inks, it helps to improve the transferability and adhesion of inks, making printed products more vivid and clear in color.

(3) In the cosmetics industry: It is often used as a lubricant and binder for powder raw materials, making the powder of cosmetics fine-textured, easy to apply, and enhancing the user experience. It also has a certain covering power, which can help improve the skin color and is often used in products such as powder compacts and loose powders.

(4) In other fields: In the paper-making industry, it can be used for surface sizing of paper to improve the water resistance and smoothness of paper.

In the pharmaceutical field, it can be used as a lubricant for medicine tablets to prevent the tablets from sticking to the punch die during the tableting process and help the disintegration of tablets.

(1) Lubrication function: In the processing of plastics, rubber, etc., it can reduce the friction between materials, make the processing smoother, improve production efficiency, and improve the surface quality of products.

(2) Release function: As a release agent, it can form a separation layer between the mold and the product, making it easy for the product to be removed from the mold, reducing the damage and deformation of the product.

(3) Stabilization function: In some polymer systems, it can play a stabilizing role, improving the heat resistance, weather resistance and anti - aging properties of materials, and prolonging the service life of products.

(4) Plasticization function: In materials such as rubber, it can increase the flexibility and plasticity of materials, improving their processing performance and service performance.

(5) Water - proof function: It can form a hydrophobic protective film on the surface of objects, improving the water - proof performance of paper, leather, fabrics, etc.

(6) Covering function: It has a certain covering power in cosmetics, which can help improve the skin color, making the skin look more uniform and smooth.
