Import Aerosil 200 Cas: 7631-86-9 — Buy in Bulk from Supplier in Canada

Aerosil 200, identified by CAS number 7631-86-9, is a fumed silica grade supplied by M Trading in Canada, characterized by its ultra-fine particle size and high surface area. This product is engineered to enhance viscosity, improve suspension stability, and prevent caking in industrial formulations. Its reinforcing properties make it a key additive in rubber, plastics, and coatings, where it improves mechanical strength and abrasion resistance.

The material’s primary particle size typically ranges from 12 to 20 nanometers, with a specific surface area of 200 ± 25 m²/g (BET method), which is standard for Aerosil 200. It exhibits a silicon dioxide (SiO₂) purity of ≥ 99.8%, with trace levels of aluminum oxide, titanium dioxide, and iron oxide as typical impurities. The product is hydrophobic or hydrophilic depending on the surface treatment; this grade is hydrophilic, as standard for Aerosil 200.

Aerosil 200 is widely used as a rheology modifier in adhesives, sealants, and inks, where it controls flow and sagging. In pharmaceuticals, it serves as a glidant to improve powder flowability, while in food applications, it acts as an anti-caking agent under regulations like FDA 21 CFR §172.480. Buyers should confirm the supplier’s compliance with relevant industry standards, such as ISO 9001 for quality management or FDA certification for food-grade use.

M Trading is a Canada-based supplier operating with an imported trust tier, indicating it sources Aerosil 200 from established producers rather than manufacturing it directly. The company’s profile does not disclose its location within Canada, years in operation, or production capacity, but its focus on fumed silica suggests specialization in industrial additives.

The supplier’s listing highlights the product’s applications in coatings, adhesives, and pharmaceuticals, but does not provide details on certifications, MOQ, or lead times. Buyers should directly confirm whether M Trading holds ISO or FDA certifications for this grade, as these are critical for regulated industries. The absence of a response rate or average response time suggests limited public engagement metrics.
