Two patent-pending BPA-free healthcare formulations boast improved  chemical resistance over traditional flame-retardant thermoplastics used for medical devices, such as FR PC/ABS, FR PC/PET and FR copolyester. Trilliant HC8910 and HC8920 healthcare grades, the latest addition to the Trilliant Healthcare Thermoplastics portfolio from Avient, Avon Lake, Ohio, were developed in response to today’s intense disinfecting protocols.

Avient's two new Trilliant HC grades boast improved chemical resistance.

Using a method adapted from ASTM D543 for ESCR (environmental stress cracking resistance), results versus alternative FR materials demonstrate superior mechanical and aesthetic property retention, and prevention of cracks and crazing after exposure to leading healthcare disinfectants such as Virex Tb, CaviCide, Vesphene IIse, and Super Sani-Cloth.

Said Matthew Mitchell, global marketing director of Avient’s,Specialty Engineered Materials,“Heightened disinfection requires materials that retain mechanical and physical performance in the face of these effective, but harsh, chemistries. By offering more robust solutions, we’re enabling healthcare OEMs to deliver more durable medical devices and equipment that resist chemical attack and serve patients longer.”

Like other materials in the Trilliant HC family, the two new grades are formulated without BPA and are available in both natural and custom colors. Trilliant HC8910 and HC8920 series of materials are now globally available. The HC8920 grades are formulated to meet certification to UL94 5VA at 3.0 mm, V-0 at 1.5 mm, V-1 at 0.75 mm. As these formulations are patent-pending, Avient has not disclosed what materials they are based on. Other Trilliant HC healthcare formulations include those based on ABS, nylons 66 and 12, PEEK, polyacetal and Eastman’s Tritan TPC.
