Grilamid TR HT 200 – First Transparent Nylon to Endure 400 Steam‑Sterilization Cycles

Grilamid TR HT 200, the world’s first transparent nylon that can be steam‑sterilized at 273 °F (134 °C) for 400 cycles without losing clarity, color, or strength, was developed by EMS‑Grivory (U.S. office, Sumter, S.C.).

Unlike conventional clear plastics that fail after a handful of autoclave passes, Grilamid TR HT 200 maintains a light‑transmission rate of over 90 % through 2 mm plaques, making it ideal for medical devices that demand repeated, high‑temperature sterilization.

Typical alternatives such as polycarbonate survive only ten steam cycles, while high‑temperature polymers like PSU, PPSU, and PEI can withstand the temperature but develop a yellow‑to‑amber discoloration that worsens with each cycle. Grilamid TR HT 200 offers the best of both worlds: superior optical clarity and chemical resistance.

Its robust mechanical properties and chemical inertness enable a wide range of applications—including transparent pump holders, filters, steam valves, container boxes, toolboxes, ventilation masks, sight windows, and more—replacing disposable components with durable, reusable solutions.

Grilamid TR HT 200 carries FDA USP and ISO approvals and has been trusted in the medical sector for over two decades, supporting devices such as syringes, containers, catheters, and face masks.
