Introducing Verge granules… a complete line of dust-free chemical and

biological carriers that feature three choices to vary the release rate of active

ingredients. Advanced processing techniques and a natural raw material are

combined to create innovative granules with unsurpassed function, uniformity,

and appearance. Beautifully spherical, your formulated products will look

and perform their very best.

Verge granules are made from millions of inert micro-particles that are

agglomerated to form a hard, dust-free core. The granules are durable

and can withstand the demands of material handling and transport, while

providing your customers with low-dust products of unsurpassed ease-of-use.

They are available in a range of disintegration rates and sizes to best fit your

end-use application.

Verge has a durable outer core that prevents tiny fragments from

breaking off, unlike traditional, irregular-shaped granules that

rub together during handling, transportation, and formulation.

Professionals and consumers will now enjoy the greater satisfaction that

comes from using a formulated product with improved handling and

reduced dust exposure.

granule technology

ultra-low dustConsumer and worker exposure to dusty formulations is a concern with

chemical formulations. Active ingredients contained in airborne dust particles

pose a risk during material handling, formulation, and application. Verge

granules are made using a unique process that makes them hard, durable and

dust free.

The pictures to the right were taken during an internal test to compare the

airborne dust emitted by traditional carriers from a common industry spreader.

A black background was used to improve the visibility of emitted dust which is

often difficult to see in sunlight. The difference is clear – Verge granules have

the lowest visible dust.

Verge granules were also compared to a popular paper-based granule often

cited by formulators as having the lowest airborne dust among commercial

granules. Side-by-side tests confirm Verge granules have lower dust than the

leading cellulosic complex granule.

uniformityFormulators have long known that smaller granules contain more active

ingredient by weight than larger granules. The result is a variable

concentration of active ingredient on the granules. (Figure 1)

Verge granules are manufactured using a unique process that creates a highly

uniform particle size and weight. This results in a more uniform concentration

of active ingredient on the particles to help you formulate with greater

precision. (Figure 1)

The problems with uniformity are magnified during application when light

granules containing more active ingredient by weight are thrown closer to the

spreader, and heavy granules containing less active ingredient are thrown

farther from the spreader. The result is variable coverage of active ingredient

across the treatment area.

Verge granules help overcome this problem. Application tests using a rotary

spreader show that Verge granules are evenly distributed across the swath

width regardless of distance from the spreader. This results in a more even

distribution of granules and active ingredient across the treatment area. (Figure

2)

You invest a lot of research dollars identifying the precise treatment rate for

your active ingredient. Choosing the right carrier can ensure your customers

will actually deliver that rate and achieve maximum performance.

versatilityVerge granules are the most flexible product line of inert carriers available

today. Our dust-free, highly uniform granules are available in three standard

sizes that cover a range of end-use applications from golf greens and turf to

aquatics. Each size is also available with three different disintegration rates

that offer flexibility to control the delivery rate of your active ingredients.

Our new state-of-the-art agglomeration plant uses a flexible manufacturing

process that also makes it possible to create custom granular formulations that

better fit your end-use application.

Physical properties such as bulk density, size, or color can be changed, or we

can create custom formulations that incorporate non-active ingredients.

Our over sixty years of mineral processing expertise has led to the creation of

an advanced platform for granulation technology to assure your success for

years to come.

SGN: A measurement developed by the Canadian Fertilizer Institute that

determines median particle size by locating the 50% retain point in a

product’s size distribution curve. The particle size in mm is multiplied by 100

and rounded to the nearest five.

Uniformity Index: Represents the “tightness of particle size distribution” for

granular materials. The higher the value, the more uniform the sample. An

index of 100 means all particles are exactly the same size.

Dust Index: A measurement of optical density of resulting dust when

granular material is dropped into a closed chamber.

Hardness: A measurement of resistance to attrition calculated by agitating

material in a pan with steel balls and measuring the resulting fragments of

material.

Liquid Hold Capacity: A measure of a sorbent material’s ability to retain

liquid and still remain free flowing, expressed as a WT%. The higher the

value, the greater percentage of liquid a sample can hold.

Angle of Repose: A measurement of the maximum angle of stable slope of

a granular material. Materials with a lower angle of repose overcome friction

at a lower angle and flow more smoothly.

Eliminating Waste

Formulating products with Verge granules has never been more clean and

safe – and better for your bottom line. Using dust-free granules avoids

the disposal of waste fines that are commonly screened from shipments of

traditional carriers. The case study below from a commercial formulation

plant is an example of the cost to your bottom line of using poor quality

granules in your formulations.

Waste fines and dust added 8% to the total cost of granules in this plant and

reduced profit margins.

Precise Formulations

Formulators understand the difficulties of loading a consistent amount of active

ingredient on granules with a large amount of fines. Fine granules have a

larger surface area to mass ratio that typically results in significantly higher

active ingredient loading versus the target formulation.

Verge granules help overcome this problem because they have a highly

uniform particle size with minimal fines. This results in a more uniform

concentration of active ingredient on the particles so you can formulate with

greater precision and make it easier to stay within regulatory tolerances.
