Product Description:

White Carbon Black (Precipitated Silica) - Key Technical Indicators

White carbon black (precipitated silica) is characterized by several critical parameters that determine its performance in different applications. Below are the main technical specifications and testing standards:

Physical & Chemical Properties

Parameter	Typical Range	Test Method	Significance
SiO₂ Purity (%)	≥ 90% – 99.5%	ISO 3262 / GB/T 20020	Higher purity = better performance in food/pharma
Loss on Drying (105°C, %)	≤ 5.0% – 7.0%	GB/T 6284 / ISO 787-2	Moisture content affects flowability
Ignition Loss (1000°C, %)	≤ 5.0% – 10.0%	GB/T 5211.3 / ISO 3262	Measures volatile content
pH Value	6.0 – 7.5 (neutral)	GB/T 1717 / ISO 787-9	Affects compatibility in rubber/plastics
Bulk Density (g/cm³)	0.15 – 0.30 (loose)	GB/T 5211.4 / ISO 787-11	Influences handling & mixi

Particle & Surface Characteristics

Parameter	Typical Range	Test Method	Application Impact
Average Particle Size (µm)	1 – 20 (nanoscale available)	Laser diffraction (ISO 13320)	Finer particles = better reinforcement
Surface Area (BET, m²/g)	50 – 400	GB/T 23656 / ISO 9277	Higher surface area = better adsorption
Oil Absorption (g/100g)	100 – 300	GB/T 5211.15 / ISO 787-5	Key for rubber & coatings
Pore Volume (cm³/g)	0.5 – 2.5	Mercury porosimetry	Affects thickeni

Key Properties:

Chemical Formula: SiO₂

Appearance: White, fluffy powder

Particle Size: Ultra-fine (nanoscale to micrometers)

Surface Area: High (50–400 m²/g, depending on grade)

Porosity: Adjustable (influences absorption and reinforcement properties)

Non-toxic & Chemically Inert (safe for food, pharmaceuticals, and cosmetics)

Performance in Key Applications

A. Rubber & Tire Industry

Reinforcement Index (Tensile strength, modulus) – ASTM D412
Abrasion Resistance – DIN 53516
Dispersibility – Microscopy & rheology tests

B. Food & Pharmaceuticals (E551)

Heavy Metals (Pb, As, Hg, Cd) ≤ 10 ppm (GB 25576 / FCC)
Microbial Limits – USP <61> / EP 2.6.12
Soluble Chlorides & Sulfates – ≤ 0.5%

C. Coatings & Inks

Viscosity Control – ISO 3219 (rheometer)

Matting Efficiency – 20°–60° gloss measurement (ASTM D523)

Storage and Handling:

• Storage: Silica should be stored in a cool, dry place, away from moisture and direct sunlight. It should be kept in airtight containers to prevent moisture absorption.

• Handling: When handling silica, it is important to avoid contact with skin and eyes. In case of contact, immediate rinsing with water is recommended. Protective gloves and goggles should be worn during handling.

Common Industry Standards

China: HG/T 3061-2020 (Precipitated Silica for Rubber)
International: ISO 3262 (Extenders for Paints), USP-NF (Pharma Grade)
Food Safety: FDA 21 CFR 172.480, EU E551
