Feature

Silica dioxide powder, also known as silica, is a common additive used in various industries, including the paper and 

ink industry. It is used to improve the properties of paper and ink, such as enhancing the hand-feeling, improving 

printability, and increasing the opacity of the ink.

When selecting a silica dioxide powder for paper ink, it is important to consider the following factors:

1. Purity: Look for a high-purity silica dioxide powder to ensure that it does not contain any impurities that could affect the 

quality of the paper or ink.

2. Particle Size: The particle size of the silica dioxide powder can affect its performance in paper ink. Smaller particle sizes 

generally provide better dispersion and improved hand-feeling.

3. Surface Area: Silica dioxide powders with a larger surface area can enhance the ink's ability to adhere to the paper, 

resulting in improved print quality.

4. Porosity: Silica dioxide powders with a higher porosity can help in absorbing ink and reducing bleeding, resulting in sharper 

and more defined prints.

5. Compatibility: Ensure that the silica dioxide powder is compatible with the other components of the ink formulation to avoid 

any adverse reactions or compatibility issues.

6. Safety: Consider the safety aspects of the silica dioxide powder, such as whether it is free from harmful substances, meets 

regulatory requirements, and has appropriate safety data sheets available.

It is recommended to consult with suppliers or manufacturers who specialize in providing silica dioxide powders for the paper 

and ink industry. They can provide specific recommendations based on your requirements and offer samples for testing and 

evaluation.
