1. Anti-blocking: The silica anti-blocking agent can form numerous fine and hard protrusions on the surface of the film, reducing the contact area between the films, lowering the surface friction coefficient, and making it easier for the films to open. 2. High Specific Surface Area: It has a high specific surface area, which makes it highly effective in anti-blocking, making it very suitable as an anti-blocking agent for film materials. 3. Good Dispersion: It can be evenly dispersed in resin, forming 10-25% anti-blocking masterbatches, which can be used in PP, PE, and other film products. 4. Optical Performance: The refractive index is similar to that of plastic materials (PE/PP), providing excellent optical properties such as transparency, turbidity, and gloss. 5. High Purity: The raw materials are of high purity, with no harmful substances to the human body. 6. Concentrated Particle Size Distribution: Provides good anti-blocking and optical properties. 7. Non-toxic and Harmless
