Detailed Description and Applications of Silica
Gas-phase method silica hydrated white carbon black
Silicon rubber: Improve anti-aging property and resilience
Plastic industry: Can improve the flexibility, strength and water resistance of plastics.
Coatings: Enhance anti-caking property; Has thickening and extinction property.
Pharmacy: Has thickening, suspending function; As carrier; As anti-caking agent.
