从China供应商批发进口Acc Microsilica — FOB条款

ACC microsilica from Xiamen All Carbon Corporation is a highly reactive pozzolanic ultrafine powder derived from amorphous silica with SiO₂ content above 90%. The supplier offers densified, undensified, and white microsilica variants with minimum SiO₂ contents ranging from 85% to 98%, processed through automated, closed-environment systems that prevent mixture contamination. This material conforms to ASTM C 1240 and EN 13263:2005 standards, and the supplier notes recognition by SGS, Exova, and other testing authorities.

The product's amorphous structure and extreme fineness, typical of silica fume produced during silicon metal or ferrosilicon alloy manufacturing, confer exceptional pozzolanic reactivity. When incorporated into cementitious systems, the ultrafine particles fill voids between cement grains and react with calcium hydroxide to form additional calcium silicate hydrate. Xiamen All Carbon Corporation has supplied microsilica since 2005, with production integrating recycle, densifying, and filling processes in a closed system to maintain consistency and stability.

Primary applications span high-performance concrete for infrastructure durability, refractory castables requiring thermal and chemical resistance, ceramics manufacturing, and chemical fertilizer production. Buyers include construction material distributors, ready-mix concrete producers, refractory manufacturers, and engineering contractors managing large-scale projects. Trade typically involves bulk bags or loose form shipment, with custom specifications available upon request. The supplier indicates capacity to fix client orders through a stable production base, though importers should confirm current MOQ, packaging options, and lead times directly.

Xiamen All Carbon Corporation is based at No.99 Lujiang Road, Xiamen, Fujian Province, China (postal code 361001). The supplier holds a harbor trust tier and reports a 0.00% response rate with zero average response hours, which indicates minimal or no engagement through the platform's inquiry system. The company has been supplying microsilica since 2005, positioning it as an established producer in this commodity segment, though the listing provides no information about factory size, employee count, or annual revenue.

The supplier's profile emphasizes automated, closed-environment processing without mixture or impurities, and claims capacity to secure stable production for consistent order fulfillment. Recognition by SGS, Exova, and other testing authorities is cited, though specific certificates or audit dates are not displayed. The product range extends beyond standard grades to custom SiO₂ content and specifications. Importers should note that verification details, factory audit status, and current production capacity require direct confirmation with the supplier, as these are not substantiated in the available profile data.
