EROL 520 SX is a polysiloxane-based emulsion that can be used as a defoamer in aqueous media. As a defoamer, EROL 520 SX helps cure foaming problems in various production processes. EROL 520 SX disperses easily in water and can be used continuously, either manually operated or by metering pump. It provides a good knock down effect while minimising the impact on oxygen transfer. This ensures optimised productivity to obtain the desired final product without affecting quality. EROL 520 SX is compliant with various regulations and does not contain any animal-derived ingredients, making it suitable for use in pharmaceutical manufacturing where strict purity is required, but also for use in food, cosmetics or more industrial processes.
