Precipitated Silica ALOS-PS-003
Inquiry
Precipitated silica ALOS-PS-003 is a high-purity form of silicon dioxide, precipitated from a silicate solution through a chemical reaction. It appears as a white, fluffy, fine powder with a large specific surface area and excellent adsorption capacity. Thanks to its unique physical and chemical properties, ALOS-PS-003 is widely used as a functional filler and performance additive in synthetic rubber products, natural rubber products, and adhesive systems. It enhances formulation stability, improves processing behavior, and contributes to superior mechanical and bonding performance.

Applications
Precipitated silica ALOS-PS-003 is a versatile functional filler widely used in synthetic rubber, natural rubber products, and adhesive systems.
- In synthetic and natural rubber, this product functions as an excellent reinforcing and filling agent. It significantly improves mechanical strength, abrasion resistance, high-temperature performance, and tear resistance, while also enhancing dielectric properties. It is particularly irreplaceable in light-colored and transparent rubber products, where it provides strength without compromising appearance, color purity, or clarity.
- In adhesive formulations, precipitated silica ALOS-PS-003 serves multiple functions. It acts as a reinforcing agent, thickener, and thixotropic modifier, helping to prevent settling, caking, and phase separation. In addition, it improves processing behavior, enhances storage stability, and promotes adhesion, making it an effective multifunctional additive for high-quality adhesive systems.
