Ürün Açıklaması
Precipitated Silica White Carbon Black
Rubber Reinforcing Filler, Toothpaste Abrasive, Coating Additive
White carbon black, chemically known as precipitated silica (SiO₂·nH₂O), is a synthetically produced amorphous silicon dioxide ultra-fine powder. This product appears as a white amorphous fine powder, characterized by very high specific surface area, porous structure, excellent reinforcing properties, good dispersibility, adsorption capacity, and chemical inertness.
Unlike ordinary fillers, white carbon black is a functional reinforcing filler capable of significantly enhancing the physical and mechanical properties of materials. It plays a high-end and crucial role in numerous fields such as the rubber industry (especially green tires), toothpaste, coatings, plastics, food, and pharmaceuticals.
Core Applications
Green Reinforcing King in Rubber Industry
- Revolutionary Filler for Tires and Rubber Products: The most important application of precipitated silica. Adding it to tire compounds significantly reduces rolling resistance, saves fuel, reduces CO₂ emissions, while improving wet grip and wear resistance.
- Exclusive Reinforcing Agent for Silicone Rubber: Provides irreplaceable reinforcement for silicone rubbers, enhancing tensile strength, tear strength, and hardness.
- Other Rubber Products: Used in shoe soles, conveyor belts, rubber rolls to improve wear and tear resistance.
Gentle Functional Agent in Daily Chemicals and Personal Care
- Toothpaste Abrasive: Food-grade high-purity precipitated silica serves as primary abrasive and thickener in premium toothpastes.
- Cosmetics: Used in pressed and loose powders as absorbent and skin feel modifier, providing silky texture.
Performance Modifier in Coatings, Inks, and Plastics
- Coatings and Inks: Functions as anti-settling agent, thixotrope, and matting agent, preventing pigment settling and improving application properties.
- Plastics: Added to films to increase clarity, strength, and anti-blocking properties.
Multi-Functional Auxiliary in Food, Pharmaceuticals, and Industry
- Food Anti-caking Agent (E551): Used in powdered foods to maintain free flow.
- Pharmaceutical Excipient: Serves as disintegrant, glidant, and carrier in tablets.
- Pesticides and Animal Feed: Acts as carrier to improve flowability and prevent caking.
Product Grading and Key Parameters
Precipitated silica is classified into numerous grades based on production process, specific surface area (BET method), particle size, oil absorption value, pH, purity, and surface treatment. Main categories include Rubber Reinforcement Grade, Toothpaste Grade, Coating Grade, Food & Pharmaceutical Grade. Hydrophobic precipitated silica offers better compatibility and reinforcement in silicone rubber and certain plastics.
Safety and Handling Notes
Precipitated silica is chemically stable and non-toxic. However, as an ultra-fine powder, prolonged inhalation of its dust may affect the respiratory tract. Dust control measures and dust masks are recommended during handling. Food and pharmaceutical grades have extremely stringent limits for impurities like heavy metals and arsenic.
Our supplied precipitated silica products feature high specific surface area, excellent reinforcing effect, uniform particle size distribution, good purity, and stable quality. We provide customized product solutions to tire and rubber product manufacturers, toothpaste producers, coating and ink companies, food additive plants, pharmaceutical factories, and chemical plants. For specific needs in areas like reducing tire rolling resistance, enhancing rubber strength, improving toothpaste mouthfeel, or adjusting coating rheology, we can recommend the most suitable grade and offer professional technical support.
