WEB EXCLUSIVE: RTP Co., Winona, Minn., has added specialty TPEs to its line of biocompatible compounds for medical devices. The 6042 MD and 6003 MD Series TPE compounds are formulated to bond with ABS, PC, PC alloys, PBT, rigid TPU, or copolyester substrates using wither multi-shot or insert-molding processes.
Naturally opaque, MD Series TPE compounds are colorable with RTP’s biocompatible color products, which provide ISO 10993 compliance in precolored resins and color masterbatches. They are also designated as change-controlled formulas to ensure there is no modification to ingredients without customer authorization. Targeted applications include surgical tools, fixation devices, and positioners that require tactile feel and slip resistance; drug delivery systems such as transdermal patches, injection pens, and inhaler pumps; and intravenous catheter systems.
These compounds have been tested for compliance with ISO 10993 (part 5 in vitro cytotoxicity, part 10 irritation, and part 11 systemic toxicity) biocompatibility standards, and documentation is available to customers. Says global healthcare manager Josh Blackmore, “To meet the growing demand for bondable TPEs in medical devices, RTP is helping product designers and OEMs by streamlining the material selection process with products that have been pretested for biocompatibility.” MD Series TPE compounds offer gamma and EtO sterilizability.

In failure analysis, there is a tendency to gravitate to a few common test protocols. But this approach can result in a mismatch of techniques to the problem.
