Chinese name: Zinc powder
English name: zinc powder
Chinese name 2: lead powder
English name 2: Zinc dust
Molecular formula: Zn
Molecular weight: 65.39
Basic physicochemical properties:
Color: dark grey; Molecular structure: spherical; Average gravity: 7.14g /cm33; Melting point: 419â??; Boiling point: 907â??.
Solubility: insoluble in water, soluble in acid and alkali, ammonia;
Stability: has a strong reducibility, and acid and base action to release hydrogen, easy to burn, combustion;
Stable in dry air, a large amount of zinc powder can be burned in humid air;
Burning in hot air produces a blue flame and produces zinc oxide.
Flying in the air, the encounter of Mars can cause combustion, the allowable concentration in the air is 15mg/m3;
It is easily caked by moisture, forming white basic carbonate in moist air and coating the surface;
The reaction with sulfuric acid and nitric acid is slow, and the reaction is accelerated when there is a small amount of other metals such as copper, tin and lead.

(Zn-66 isotope of natural composition).
Chemical purity: 99.995% - 99.999%, average particle size 3-5 microns. Quantity: up to 3000 kg per month, in batches from 50 kg.
Since it is a medium size powder, manufactured only with electrolytic zinc of a high purity, it is particularly recommended to be used in organic and inorganic paints that will be applied in medium to thick layers (40 to 60μm): industrial protective covers and primers for construction. The processing of this product ensures optimal dispersion ability in the base of the mill, the low surface of its particles considerably minimizes problems related to reactivity.
Zinc Stearate Typical Properties
Item Standard
Appearance White fine powder
Loss on drying(%) 1.0
Zinc Assay(%) 10.3-11.3
Free acid(%) 1.0
Finess(325mesh) 99%
Melting Point 115-125
Zinc Stearate Usage
1. Used as a softening lubricant for rubber products, a polishing agent for textiles, a stabilizer for polyvinyl chloride plastics
2. Used as a stabilizer for polyvinyl chloride plastic products, a softener for rubber products
3. Used in the formulation of the industry, curing oils and lubricants, as well as paint drying agents. It is used for the processing of PVC and rubber non-toxic products, which can effectively improve the photothermal stability of PVC and rubber products. The dosage in PVC processing is usually <1 part; it is used in rubber products, also used in PP, PE, PS, EPS polymerization. The additive and pencil lead are generally used in an amount of 1 to 3 parts.

Basic zinc carbonate(Transparent Zinc Oxide Powder), is a kind of inorganic carbonate, mainly as a raw materials of ceramic and lithopone manufacturing. Its specially used in transparent rubber products because of its refractive index similar to rubber. Bellow are the advantages in application in rubber
1. It is able to increase the thermal conductivity glue, improve the thermal conductivity and the curing rate, especially suitable for hot air vulcanization process.
2. It can improve the stability of the shape of semi-finished products in the curing process, which is suitable for non-model products (such as the based products which is the use of continuous vulcanization technology).
Zinc Oxide Powder is white colored odorless inorganic compound used as most important additive in cement, rubber, plastics, ceramics and glass. It is insoluble in water and is highly effective.
