Universal
Flowability.

HC-100 is engineered as the universal flow standard for the Silfeed HC-Series, making it the optimal hydrophobic silica carrier for a wide range of feed premix applications. It is particularly well-suited for vitamin-mineral premixes, trace mineral blends, and general-purpose additive premixes where reliable anti-caking performance and moisture resistance are the primary requirements.

The product's D50 particle size of 10–15 μm provides an ideal balance between absorption capacity (≥280 g/100g oil absorption) and flowability (Angle of Repose ≤35°), ensuring smooth operation on high-speed automated dosing lines without bridging or inaccurate metering. In tropical production environments where humidity regularly exceeds 90% RH, HC-100's ≥110° contact angle prevents the moisture adsorption that causes standard precipitated silica carriers to cake and clump.

HC-100 is the recommended starting point for operations evaluating a switch from untreated silica, calcium carbonate, or clay-based carriers. Its broad compatibility with standard premix formulations and low inclusion rates (0.5–2%) make it a drop-in replacement that typically requires minimal process adjustment.

Silo bridging — the formation of stable arches of material that block flow from storage bins — is one of the most costly operational problems in automated feed mills, particularly in tropical climates. HC-100 eliminates this problem through its molecularly engineered hydrophobic surface, which prevents the primary mechanism that causes bridging: moisture-mediated particle adhesion.

In standard hydrophilic silica or mineral carriers, atmospheric moisture creates liquid bridges between particles through capillary condensation. These liquid bonds dramatically increase inter-particle friction and cohesion, transforming a free-flowing powder into a cohesive mass that cannot flow under gravity.

HC-100's ≥110° contact angle eliminates capillary condensation entirely. The silane treatment creates a hydrophobic molecular shield on every particle surface that repels water at the molecular level — governed by the Laplace pressure equation, which makes the pressure within each pore positive for water, effectively pushing moisture away.

Field data confirms that operations switching to HC-100 in high-humidity environments achieve an Angle of Repose of ≤35° (compared to 45°+ for untreated carriers), eliminate pneumatic line blockages, and reduce cleaning-related downtime by an average of 30%.

Operations that switch from traditional carriers to Silfeed HC-100 typically see positive ROI within the first production quarter, with the most significant savings appearing across three categories.

When current carriers lose 30–40% of active ingredient potency during processing, nutritionists compensate by over-formulating — adding 15–20% excess active ingredient as a "safety margin." HC-100's moisture-resistant carrier performance preserves active potency, eliminating the need for this safety margin.

By eliminating caking and bridging, HC-100 extends cleaning intervals from as frequently as every 48 hours to 168 hours or more. This translates directly into increased production capacity and reduced labor costs.

Eliminating silo bridging and pneumatic line blockages prevents the batch losses, rework, and off-spec production that result from flow interruptions. The 99.8% dosing accuracy also reduces giveaway.
