Styrene-DVB Copolymer Beads for Well Drilling, Grinding Media, Absorption, and Precision Fillers

Styrene-DVB copolymer beads are plastic spheres that are converted into ion exchangers and adsorbents. These tough, plastic beads act like plastic ball bearings and function as a lubricant in well drilling applications and are useful as grinding media for deburring and deflashing or grinding kaolin clay. Some grades produced with a very low ash content, can be ground and used as fillers for investment casting. Because they are highly cross-linked, styrene-DVB copolymer beads are insoluble in organic solvents and do not melt at elevated temperatures.

Dow's styrene-DVB copolymer beads have been used successfully in the following applications:

Lubrication
Void Maintainers
Grinding Media
Adsorption
Precision Fillers
