​Eastman Introduces Opaque Polymer for Electronic Device Housings

New addition to Tritan™ portfolio addresses need for chemical compatibility with aggressive disinfectants


Kingsport, Tenn. Feb. 12, 2014 — Responding to a market need for a suitable material to use in hand-held and other electronic medical device housings that is tough and resistant to aggressive cleansers and  disinfectants, Eastman Chemical Company is expanding its Eastman Tritan™ copolyester portfolio for the medical market with the introduction of Tritan™ copolyester MXF121. The opaque material will be showcased at the Medical Design & Manufacturing (MD&M) West show Feb. 11 to 13 in Anaheim, Calif.

In addition to its chemical resistance and toughness benefits, Eastman Tritan™ copolyester MXF121 meets flame resistance safety ratings established by Underwriters Laboratories (UL). Tritan MXF121 is a bisphenol A (BPA)-free alternative to polycarbonate (PC) and PC/acrylonitrile butadiene styrene (ABS) that can stand up to today’s aggressive disinfectants and withstand the stresses of daily use and handling.

Combating HAIs
Hand-held and other medical electronic device housings are used in a health care environment that demands vigilance to prevent hospital-acquired infections (HAIs), with health care facilities using increasingly aggressive cleansers and disinfectants. Eastman Tritan™ copolyester MXF121 provides excellent chemical resistance against these cleansers and disinfectants, including Virex® TB. Many products used to combat HAIs are chemically incompatible with thermoplastics such as PC and PC/ABS, potentially resulting in compromised performance due to cracking or crazing.

“Eastman Tritan™ copolyester MXF121 can help enhance product value by providing greater product durability and reduced product failure,” said Gopal R. Saraiya, global segment leader, medical devices, Eastman. “Tritan MXF121 offers exceptional chemical resistance for a wide variety of medical electronic device housings that may come into contact with these cleansers and disinfectants.”

Hand-held and other medical devices are subjected daily to conditions that require impact resistance and toughness. Components and devices molded from Eastman Tritan™ copolyester MXF121 can have the same outstanding toughness and durability the Tritan portfolio is known for in the medical market. The toughness and chemical resistance of the material can translate into fewer broken parts, reduced device failures, less waste and greater peace of mind for health care professionals and patients.

High standards
Thermoplastics used in hand-held and other medical electronic device housings are often required to meet flame resistance safety ratings established by UL. Eastman Tritan™ copolyester MXF121 received a UL 94 V2 rating at 1.5 mm. Tritan MXF121 also meets sustainability needs as it is made without BPA, halogens or ortho-phthalate plasticizers. In addition, its flame-retardant additives don’t contain antimony, bromine or chlorine.

Eastman Tritan™ copolyester MXF121 benefits from the Eastman Color Technology Center, a leader in color theory and application since 1934. The center meets the highest standards of color match, quality, consistency and performance.

“Eastman has a vast knowledge of polymer color, appearance and additive technology, and we offer an unsurpassed palette of colors, including custom colors that meet brand owners’ stringent color specifications,” said Saraiya. “Tritan MXF121 can be precisely matched to a brand palette while ensuring color stability and vibrant aesthetics, supporting a consistent and lasting brand impression.”
