DOW XIAMETER APW-4253 Defoamer

DOW XIAMETER APW-4253 is a 12.5% active silicone powder defoamer built for high-foam laundry setups. It comes as white-to-gray free-flowing granules (0.9 g/cm³ bulk density), works stably at pH 3-12 and ≤80°C, enabling fast foam collapse (over 24 hours of suppression) in detergent powders. ISO 9001 and REACH certified, it cuts mineral oil defoamer use by 40% via better dispersion in high-surfactant mixes.
