American Society for Testing and Materials (ASTM)
Definitions: taken from “Standard Test Methods for Sorbent Performance of Adsorbents – ASTM Designation F726-99
Sorbent:
"An insoluble material or mixture of materials used to recover liquids through the mechanisms of Absorption or Adsorption or both"
Adsorbent:
“An insoluble material that is coated by a liquid on its’ surface including pores and capillaries without the solid swelling more than 50% in excess liquid.”
Absorbent:
“ A material that picks up and retains a liquid distributed throughout its’ molecular structure the solid to swell (50% or more). The absorbent must be at least 70% insoluble in excess fluid”.
Thickener:
“ as a material (usually of higher molecular weight) that is soluble in excess liquid. These go from dry to gummy (viscoelastic) to flowable and then soluble. The final viscosity depends only on solid ratio.”
Imbiber Beads® is the only product available that meets ASTM PERFORMANCE SPEC’S F716 & “ EPA OIL PROGRAM ” definitions for AB-SORPTION.
Imbiber Beads ®ABsorbent -True ABsorbent products
(demo packet) 'drink' compatible liquids into their molecular structure. There is no practical way to make the Imbiber Beads® release once it has been "Imbibed."
Typical Adsorbents - ADsorbent - Products include plastic fibre, cellulosic fibre, mats & product
will release their contents under pressure, gravitational pull, or will leach their contents in water.
IMPORTANT: Imbibitive Technologies Corporation does not recommend the use of Imbiber Beads® or any other finely divided organic sorbent material with oxidizers.
