Advantages and Characteristics of Zinc Sulfide:

1. Exceptional Optical Properties:

High refractive index: Zinc sulfide exhibits a refractive index of 2.37, making it valuable in optical applications such as lenses and optical fibers.

Phosphorescent properties: Certain zinc sulfide compounds, such as zinc sulfide doped with copper, emit a characteristic glow after exposure to light, enabling their use in glow-in-the-dark products and luminescent displays.

2. Thermal Conductivity:

High thermal conductivity: Zinc sulfide demonstrates excellent thermal conductivity, surpassing that of alumina. This property makes it suitable for applications requiring efficient heat transfer, such as thermal interface materials and thermal management systems.

3. Chemical Stability and Purity:

High purity: Zinc sulfide products are manufactured with stringent quality control measures to ensure high purity levels. They are free from harmful trace elements, guaranteeing stability and reliability in various applications.

Chemical resistance: Zinc sulfide exhibits excellent resistance to corrosion and chemical degradation, making it suitable for use in harsh environments and chemical processes.

4. Flame Retardancy and Smoke Suppression:

Fire-resistant properties: Certain zinc sulfide variants can replace Diantimony trioxide (Sb2O3) in flame retardant plastics, providing flame resistance and smoke suppression capabilities. This feature enhances the safety of products in fire-prone environments.

5. Anti-Aging and Weather Resistance:

Anti-aging effects: Zinc sulfide acts as an effective anti-aging agent in plastics and coatings by preventing metal ions from entering the polymer lattice, thus improving their weather resistance and prolonging their lifespan.

Excellent thermal stability: Zinc sulfide maintains stability at temperatures below 350°C, exhibiting superior thermal resistance compared to other compounds like titanium dioxide (TiO2).

Zinc sulfide products have the following applications:

Glass fiber reinforced plastics: Zinc sulfide can be used as a filler in glass fiber reinforced plastics to improve the strength and rigidity of the plastics.

Thermoplastics: Zinc sulfide can be used to improve the processing and mechanical properties of thermoplastics.

Elastomers: Zinc sulfide can be used to prepare rubber products to improve the hardness and wear resistance of elastomers.

UV coating: Zinc sulfide is used as a light stabilizer in UV coatings to improve the weather resistance and UV resistance of the coating.

Friction materials: Zinc sulfide can be used to prepare friction materials, such as brake pads, clutch linings, etc.

Fluorescent materials: Zinc sulfide has fluorescent properties and can be used to prepare fluorescent materials, such as phosphors, fluorescent paints, etc.


When selecting zinc sulfide products, it is crucial to consider the following factors:
