RFID bead labeling device capable of withstanding during and after vulcanization of rubber articles and maintaining RFID operability for identification purposes

摘要

An RFID-enabled bead label prior to curing based on an RFID inlay structure consisting of an aluminum antenna etched on a high temperature resistant polyimide film connected to an integrated memory circuit positioned on the surface of the polyimide film is disclosed. This RFID inlay is further inserted into the overall label structure having a plurality of layers, including, for example, a plurality of polyester layers and a plurality of high temperature resistant adhesive layers, bonding/attaching the layers together, the plurality of layers comprising the labels on the tire. It further protects and insulates the RFID inlay while being coupled to an external bead (or sidewall). The compositions/devices disclosed herein can be used for electronic identification when applied to rubber-based articles (eg tires) prior to being subjected to the stresses associated with the normal use of such articles during the vulcanization process and manufacturing process.
