Abstract:
     The invention relates to an electric detonator used plunger. The plunger material at least includes high pressure polyethylene that takes up 6.7-12.8Wt%, rubber that takes up 38.4-46.7Wt%, charcoal black that takes up 25.5-30Wt%, plasticizer that takes up 13.3-14.8Wt% and auxiliary agent that takes up 3.3-8.5%. The rubber could be chloroprene rubber, poly butadiene, and polyisobutylene rubber. The leg wire is set on the plunger. When the plunger is formed, the insulation resistance between the leg wire and the plunger is 1Kohm to 20Mohm. The electric detonator used plunger has good safety and fast electric conducting speed.
