DOW XIAMETER AFE-0020 is a 20% active silicone defoamer emulsion built for harsh industrial settings. It is a grayish-white homogeneous liquid (700 mPa·s viscosity), stays stable at pH 3.5-5 and ≤100°C, and enables fast foam collapse (over 48 hours of suppression) in liquid detergent bottling and food packaging systems. FDA 21 CFR 175.300 and REACH certified, it cuts mineral oil defoamer use by 40% via optimized dispersion in high-shear processes.
Quick Defoaming Action: Nano silicone particles lower surface tension to 24.8 dyn/cm within 10 seconds.
Ultra pH Adaptability: Works effectively in pH 1.5-13 systems, including caustic wastewater.
Food Contact Compliance: Meets GB 9685-2016 standards for food contact packaging.
Extended Shelf Life: Maintains stability for 360 days in sealed containers stored at 5-35°C.
Cost-Effective Performance: Delivers 30% higher defoaming efficiency at 0.01%-0.05% dosage.
Liquid Detergents: Controls foam during laundry detergent bottling (pH 8-10).
Food Packaging: Manages foam in adhesives (compliant with FDA 21 CFR 175.300).
Industrial Cleaning: Suppresses foam in pH 14 alkaline degreasers.
Textile Dyeing: Reduces steam consumption in jet dyeing machines.
Paper Pulping: Improves drainage efficiency in kraft pulping (pH 12-13).
