Why are Emulsifiable Concentrates less likely to plug screens or nozzles?

Emulsifiable concentrates, often referred to as EC formulations, are designed to be mixed with water and form a stable emulsion. One of the key properties of these products is that they typically have non-abrasive formulations. This means that they do not contain solid particles or abrasive agents that could accumulate and cause blockages in systems such as screens or nozzles.

Because emulsifiable concentrates are primarily liquid with very small droplets, they flow smoothly through application equipment. This reduces the likelihood of clogging compared to other formulations that might contain higher solid content or abrasive materials. Systems that plug are often caused by particles that do not dissolve or disperse properly. Therefore, the smooth, uniform nature of emulsifiable concentrates allows for reliable application without frequent maintenance to clear blockages.

Additionally, their low viscosity nature and the presence of inert ingredients both contribute to their ease of handling and application, but the defining factor leading to reduced plugging is their non-abrasive formulation which minimizes the potential for mechanical interference in spray equipment.
