Chemi Tech Defoamers Solve Foam Challenges in Pesticide Production

Foam formation during pesticide manufacturing severely impacts efficiency and quality. In reactor heating, raw material mixing, and filling stages, surfactants and mechanical agitation trigger foam, causing overflow, equipment scaling, and even shutdowns. Chemi Tech’s high-temperature-resistant defoamers address these issues through dual mechanisms:

Molecular-level penetration: Low-surface-tension components rapidly invade bubble films, disrupting elasticity and accelerating drainage to rupture foam;

Stability enhancement: Silicone-polyether composite structures maintain activity under high temperatures (80–120°C) and extreme pH, suppressing foam regeneration.

Agrochemical Production Case

An herbicide manufacturer faced 20% batch overflow during acetochlor distillation. After adding 0.1% Chemi Tech KM-380series defoamer:

Overflow reduced to 0%: 20 consecutive batches completed without overflow, reactor utilization increased by 25%;

Energy consumption lowered: Distillation time shortened by 15% due to improved heat transfer;

Product purity optimized: Active ingredient variability narrowed to ±0.5% with reduced residue.

Technical Advantages:

Broad compatibility: Suitable for EC, SC, WG formulations, with pH tolerance of 3–12;

High efficiency at low dosage: Only 30–200 ppm required, no impact on formulation clarity or efficacy;

Process readiness: Direct addition without pretreatment, dispersible under high-speed stirring.
