RTEC SteelHT is chemical resistant RFID tag with integration of injection molding. Integrated injection molding makes the tag as a whole without any gaps. The ceramic substrate and the integrated injection molding make this hard tag not only resistant to high temperature, but also anti-corrosion, and any acid and alkali solution will not enter the inside of the tag. Therefore, SteelHT is a combination of long range passive RFID tag, most rugged RFID tag, ultra high temperature RFID tag, most durable RFID tag, and anti-corrosion RFID tag. This uhf tag is truly the best solution for RFID in manufacturing industries.
