More info

Silica Powder is an ultrafine inorganic non-metallic powder material made from natural quartz (silicon dioxide, SiO2) through processes such as grinding, classification, and purification. It possesses multiple functions, such as acting as a carrier, a nuclear agent, a high-coverage powder, and a dispersion aid. It also features high whiteness, high hardness, ultrafine particle size, and uniform distribution. It has excellent compatibility with resins, rubbers, and other materials. Silica powder is not only a powder but also a fundamental material for electronics, new energy, and high-end manufacturing. Available in a wide range of specifications, HM can supply high-quality silica powder, nano-silica powder, silica spherical powder, and surface-modified silica powder, offering customized solutions to meet specific requirements.

Silica Powder vs. Conventional Fillers

Property / Characteristic	Silica Micro-Powder	Conventional Fillers (e.g., Calcium Carbonate / Talc)
Composition & Purity	High Purity SiO₂ ≥ 99.5% • No crystalline water, stable structure	• Contains Calcium Carbonate (CaCO₃), Talc (Mg₃Si₄O₁₀(OH)₂) • Higher impurity content, lower purity
Chemical Resistance	Resists Strong Acids & Alkalis (pH 1-14) Fe₂O₃ ≤ 0.03%, high stability	Calcium Carbonate decomposes in acid (dissolves at pH < 6) • Talc has weak alkali resistance
Weatherability	UV Resistance > 5000 hours Excellent color stability, △E < 1.0	Prone to Yellowing (e.g., Calcium Carbonate: △E > 5.0 after 3 months)
Compatibility & Processability	Suitable for both Water & Oil-based Systems Customizable Particle Size (1-80µm)	• Calcium Carbonate is limited to oil-based systems • Talc is difficult to disperse
Mohs Hardness	7.0, similar to quartz, high wear resistance	• Calcium Carbonate: 3.0 • Talc: 1.0
Oil Absorption	25-29 g/100g Low oil absorption reduces resin demand, improving cost-efficiency	• Calcium Carbonate: 40-50 g/100g • Talc: 35-45 g/100g
