GreenTru Corncob Blast Media from Green Products Company is a valuable media because it is highly absorbent but also free-flowing, biodegradable, renewable and abrasive.


  • GreenTru three most common industrial corncob grades are 1014, 1420 and 2040. All three products are used as media for pressure blasting, log home maintenance, tumbling and vibratory finishing of metal parts.  The appropriate size is usually the one where the particles are small enough that they will not lodge in openings and cavities.
