Viscosity control for a stable suspension

UPFLOW SC Technology: Stability and Homogeneity in Suspension Concentrate Formulations

UPFLOW SC technology, developed by AFEPASA, is specifically designed for the manufacture of products formulated as suspension concentrates (SC), in which solid particles of the active ingredients are finely dispersed and suspended in a liquid medium.

This technology combines a high-precision milling process using state-of-the-art equipment with a physical mixing and homogenisation system specifically designed to achieve uniform particle distribution. The result is a stable, homogeneous suspension concentrate designed to maintain its physical characteristics during storage and subsequent use.

Precision milling and particle size control

One of the key elements of UPFLOW SC technology is the precise control of particle size. Through an advanced milling process, the solid particles present in the formulation are reduced and homogenised, preventing the presence of coarse fractions and promoting their proper distribution throughout the liquid medium.

A fine and homogeneous particle size contributes both to the stability of the suspension and to its performance during preparation and application. It also enables uniform formulations in which the active ingredient remains properly distributed throughout the product.

The technology allows the rheological properties of the formulation to be adjusted in order to reduce particle sedimentation and prevent phase separation during storage. This balance between particle size, viscosity and suspensibility results in a physically stable and homogeneous formulation over time.

Thanks to this stability, products developed with UPFLOW SC technology can be stored in their original packaging for up to three growing seasons while maintaining the characteristics required for their correct use, provided that the specified storage conditions are observed.

Excellent performance during preparation and application

The advantages of UPFLOW SC continue once the product reaches the field. The absence of coarse particles helps to reduce the risk of filter and nozzle blockages, promoting uniform spraying and continuous operation of application equipment.

Its high suspensibility also facilitates the rapid homogenisation of the product in the spray tank, keeping particles uniformly distributed and reducing the risk of sedimentation or precipitation during preparation and application.

In this way, the formulation helps maintain a consistent product concentration in the spray solution, promoting uniform distribution across the crop.

Balance between stability and ease of pouring

An SC formulation must be sufficiently stable to keep particles suspended while also maintaining adequate fluidity for easy use. UPFLOW SC has been developed specifically to achieve this balance between stability and fluidity.

Viscosity is carefully calibrated to allow easy pouring and efficient emptying of the container, facilitating product dosing and handling. This helps reduce the amount of product remaining inside the packaging and minimise potential losses during use.

Technology designed from formulation to field application

UPFLOW SC integrates the main parameters that determine the performance of a suspension concentrate: precision milling, homogeneous particle size, viscosity control, high suspensibility, storage stability, and ease of handling and application.

The result is a technology that provides advantages throughout the entire product-use cycle, from manufacturing and storage to spray preparation and final application to the crop.

With UPFLOW SC, AFEPASA applies its expertise in milling, formulation and process technology to develop suspension concentrates that combine stability, homogeneity, ease of use and high performance in the field.
