Brown Fused Aluminium Oxide
Type: AP-17 It is one type of non-calcined Brown Fused Aluminium Oxide grain for Coated Abrasive application, the grain shape is very sharp, the strip and needle shape are well kicked out of the grains. With the concentrated size distribution and dust collected by well water washing, It can be used for producing all kinds of Coated Abrasives Products, such as sand paper, cloth, rolls, belts, etc. Our product is produced strictly based on the FEPA standard. Process way: Rolling Machine Process |   |
