additives feature | Anti-counterfeiting technologies
Grafe offers a product- marking
masterbatch that can be
detected using x-ray fluores- cence analysis
challenges.” The technology can generate an infinite number of unique marks and is currently in trials for various plastic applications.
Anti-counterfeiting formulations New anti-counterfeiting masterbatches, compounds, and services have been introduced in the past few years. PolyOne launched Percept Authentication Technologies in 2013, and it is now available globally. Percept solutions include masterbatch formulations and selection services for anti-counterfeiting options. “By incorpo- rating design and consultative services, PolyOne can help customers understand the track and trace technologies available to them and how best to implement the right ones in their supply chain,” says Petrie. Technologies available include overt solutions such as colour-shifting colorants and laser-marking additives, plus covert solutions such as energy-sensi- tive and microscopic taggants. Grafe offers a product-marking masterbatch based
on a combination of chemical substances that can be detected in the end-product both qualitatively and quantitatively using x-ray fluorescence analysis (XRF). The marker masterbatch can be used alone in a range of plastics, including use in synthetic yarn. Colours can also be added to the masterbatch. Celanese announced a range of detectable polymer
PolyOne’s Versaflex CE TPEs for consumer electronics are offered with Percept Authentication Technologies
technologies in March 2014 to help OEMs and suppliers reduce the potential risk and loss of revenue from counterfeits in automotive parts, consumer products, medical devices, packaging and consumer electronics. Although Celanese’s analytical department has
extensive testing capability for analyzing the base polymer as well as the different additives in the formulation to identify if it is an original Celanese grade, this tends to be time consuming and costly. To facilitate identification of counterfeit material by their customers, other anti-counterfeiting additives can be added to the
material including UV-detectable technologies and optically verifiable pigments/microtaggants that can be chosen for a specific product, customer or application. Celanese also offers laser-markable grades that
allow the final part to be marked with a visible barcode, such as manufacturer, batch number and raw material/ batch.
“The decision about the choice of the anti-counter-
feiting solution should be based on criteria such as does the customer want a visible or invisible marker? Is the method compatible with the existing design? Does it have to be specific to a customer/application/production site or does the customer only want to know if it is a Celanese grade? This decision should be carefully taken after detailed discussion of customer requirements,” explains Kirsten Markgraf, product development leader at Celanese.
