Thermoform Test Cards – Rubber


Hard “plastic” (PETG) cards holding any size contaminant and designed especially for rugged use.


Thermoform Test Cards – Rubber (2.5″x4.25″) are made with food grade polyethylene (PETG).  They uniquely form a tight, solid structure surrounding the rubber or other contaminant type. Accordingly, the cards are particularly appropriate for wet or humid applications.  They can withstand more wear and tear than a laminate card. For all intensive purposes, the plastic is hard and clear and invisible under x-ray. As required, cards are available in a variety of sizes.  Purchase cards with a single or multiple balls (12+ special pricing).  All “contaminant” types, (Fe, NFe, SS 316, Ceramic, SLG Aluminum, Acetal (Delrin), PTFE (Teflon) and Rubber) are available.  Rubber contaminant type is listed hereONLY single seed cards are available on the website.  Test Cards – Rubber sold Individually.  Email or call 866-691-8560 TO ORDER MULTI-CARDS.
