Biodegradable polymer system for controlled herbicide volatility
Envelop® technology offers a biodegradable polymer system for creating microcapsules of agrochemical actives. This innovative solution allows for controlled release, integration of additives like UV stabilizers, and eliminates the need for solvent evaporation.
Overview
Envelop® technology introduces an advanced biodegradable polymer system that revolutionizes the encapsulation of agrochemical actives. This solution enables the formation of microcapsules upon dilution with water, containing agrochemical actives in a controlled manner. Unlike traditional capsule suspensions, Envelop® incorporates biodegradable and food-grade materials, allowing for customization in density, thickness, and particle size. This technology facilitates the straightforward addition of additives such as UV stabilizers and additional active ingredients, enhancing the versatility and effectiveness of herbicide applications.
