PROBLEM TO BE SOLVED: To provide a plastic abrasive with outstanding antistatic function which prevents accumulation of static electricity of a whole abrasive in processing, and also to provide a blast processing method using the same. SOLUTION: In the plastic abrasive used for a blast processing, nonionic surface active agent in 0.1 to 5 wt%, preferably 0.5 to 1 wt% of a base material is mixed. The HLB of the nonionic surface active agent is preferably 8 to 19, and the particle diameter of the resin base material is also preferably 20 to 5000μm. The blast processing method uses this plastic abrasive. COPYRIGHT: (C)2005,JPO&NCIPI
