Plastic sealing plug for locking opening i.e. lacquer discharge opening, in thin-walled flat component i.e. vehicle body sheet, has sealing lip made of rubber elastic, and chemically connected with base body

摘要

The plug (1) has a base body (2), to which retaining feet (6) are formed for locking the plug in openings, where the base body is made of ductile rigid-plastic. A sealing lip (3) is made of rubber elastic, and sectionally surrounds the base body on edges. The sealing lip is chemically connected with the base body. The sealing lip is molded on the base body, and comprises a thermoplastic elastomer, where the base body is glass-fiber reinforced, and comprises potentially acid-generating material.
