Dowsil ACP-2000 Defoamer

DOWSIL ACP-2000 is a 100% active silicone defoamer engineered for corrosive foam media in chemical pulping. Its unique polysiloxane formulation enhances the performance of mineral oil-based defoamers, with a dynamic viscosity of 2000–5000 cP and a boiling point >100°C—making it suitable for extreme pH (2–12) and high-salinity environments. It optimizes foam collapse efficiency (8+ hours of suppression), reduces pulp washing losses by 20%–30%, and complies with FDA 21 CFR 176.210 for indirect food contact.

Product Information of Dowsil ACP-2000 Defoamer

  1. Synergistic Efficiency: Delivers 50%+ foam suppression when blended with mineral oil defoamers, ideal for kraft pulping at ≤100°C.

  2. Harsh Condition Tolerance: Remains active under high shear (≥5000 rpm) and in the presence of oxidants (e.g., chlorine, H₂O₂).

  3. Long Shelf Life: 360-day stability with no stratification when stored at 4–50°C.

  4. Cost-Effectiveness: 0.1%–0.3% dosage reduces oil-based defoamer usage by 30%.

  5. Easy Integration: Liquid premix form, compatible with existing dosing systems.
