Corn cobs are hard, low density, natural abrasive. Blasting grains are produced from crushed, cleaned and sifted corn cobs. Corn cobs belong to reusable abrasives and feature low impact on the air-blasted surface without damaging underlying material. Corn cob abrasives are 100% natural product and they are free of respirable crystalline silica SiO2.
