Purging agent and purging method |
| abstract |
A purging agent which contains an ethylene-vinyl alcohol copolymer and which satisfies the conditions specified by the equations (1) and (2) below:where BT(120) is weight loss (%) on heating in nitrogen at 120° C. for 24 hours, and BT(250) is weight loss (%) on heating in nitrogen at 250° C. for 6 hours, rapidly discharges residual thermoplastic resin containing EVOH from molding equipment, and also rapidly discharges itself when a fresh resin is fed again to the equipment. This leads to a remarkable reduction in loss due to residual purging agent. In addition, the purging agent causes only a small amount of resin to stick to the equipment, even after repeated purging. After purging, it is possible to restore normal operation within a short period of time. |
