Dowsil ACP-3000 Defoamer

DOWSIL ACP-3000 is a high-performance silicone defoamer engineered for corrosive environments like chemical pulping. It features 100% active polysiloxane, maintaining stability across pH 2–12 and temperatures ≤150°C. Leveraging nano-dispersion technology, it rapidly collapses foam (dynamic surface tension ≤25 mN/m) and reduces pulp washing losses by 20%–30%. Its emulsifiable nature (dilutable to 1%–5%) synergizes with mineral oil-based defoamers, and it complies with FDA 21 CFR 176.210 for food-grade pulp applications.

Product Information of Dowsil ACP-3000 Defoamer

  1. Harsh Condition Tolerance: Resists strong acid/alkali (pH 2–12) and high shear (≥5000 rpm), ideal for 80–100°C kraft pulping.

  2. Long-Lasting Control: Provides 8+ hours of foam suppression; 0.05%–0.3% dosage minimizes replenishment costs.

  3. Eco-Compliance: APEO-free, VOC<50g/L; certified under EU REACH and China GB 24408.

  4. Easy Integration: Pre-emulsified liquid enables direct dosing, no equipment modification needed.

  5. Cost Efficiency: Blending reduces mineral oil defoamer usage by 30%, lowering total cost of ownership (TCO).

Areas of Application of Dowsil ACP-3000 Defoamer

  1. Chemical Pulping: Suppresses black liquor foam in kraft/sulfite pulping (0.05%–0.2% dosage).

  2. Paper Bleaching: Controls foam in H₂O₂ bleaching to ensure uniform whiteness.

  3. Wastewater Treatment: Reduces foam in high-COD aeration tanks.
