Improving Granule Performance and Stability

Granule integrity is critical during production, storage, and transport, but must be carefully balanced with the required disintegration rate during application. This balance is essential across applied, soluble, and water-dispersible granules (GR, SG, WG), where both physical durability and application performance must be maintained.

Achieving the optimal balance between binding strength and granule disintegration can be challenging, particularly across different formulation types, active ingredient combinations, and processing methods.

Supporting granule performance across formulations

Selecting the right co-formulant is critical for balancing granule integrity, dust reduction, processability, and disintegration performance across GR, SG, and WG formulations. Different formulation types and application conditions place varying demands on binder and dispersant performance, particularly where electrolyte stress, tank-mix compatibility, mechanical durability, and application performance can affect final granule quality. We offer a range of dispersants and binders designed to address specific formulation challenges and optimize performance under different processing and application conditions.

The Ufoxane® range supports rapid wetting, efficient granule disintegration, and stable tank-mix behaviour in complex WG systems, including under challenging high-electrolyte conditions. Complementing this, the Greensperse range (S7, S9 and SL-8) has been developed for formulations that needs to be further optimised to handle more challenging tank-mix conditions where wettability, disintegration and tank-mix stability can be a challenge. Greensperse CA-N has been developed especially for use in granulated products where binding performance is the key performance parameter (applied granules, GR / soluble granules, SG).

With multifunctional chemistries designed to adhere to a wide range of particle surfaces and powder qualities, these technologies support reliable performance across diverse formulation systems and processing conditions.

Trial data: Improved Granule Strength and Durability 

Greensperse® CA-N is designed to improve the strength and durability of granulated formulations while maintaining rapid disintegration when applied. In a 50% flonicamid granule formulation produced by extrusion, Greensperse CA-N delivered excellent resistance to attrition while achieving complete disintegration after fewer than 10 inversions following accelerated storage.

The results demonstrate the ability of Greensperse CA-N to support robust granule formulations that withstand handling, transport, and storage without compromising performance at application.
