Creative Materials offers a variety of products for the radio frequency identification device (RFID) market including standard and custom formulations for unique antenna designs, microchip attachment, and encapsulation.

Passive antennas are produced using flexographic or roll-to-roll screen printing process utilizing conductive inks. These materials are used to enable the radio waves from the reader to direct them to the microchip, where the energy is then collected and sent back to the reader for data transfer. The microchips are typically bonded with snap cure anisotropic or isotropic conductive epoxies providing flexibility, high reliability and durable bond strength.

RFID has emerged as an innovative technology expanding beyond its historical applications in aerospace field. RFID is now considered a established technology with numerous applications with implementation across a wide range of industries and markets. This knowledge is a testament that we are solving problems and delivering real time data for beneficial analysis worldwide. Tagging products with RFID allows users to automatically and distinctively identify and track those items. RFID costs continues to decrease, making it more and more viable in emerging industries.
