Ultem(PEI) Machining
Controlled Fluidics offers Ultem machining for parts that require a higher level of chemical and temperature resistance as well as having flame retardant and USP Class Vl rating options. Ultem is ideal for diagnostics, medical devices, transportation, electronics, and other applications that need these properties. Ultem is a very common material selection for diffusion bonded multilayer manifold applications due to its many advantages.
At Controlled Fluidics, we can assist with material selection to aid in prototype development as well as full plastic machining production runs.
Depending on the scope of your project, the turnaround for Ultem machining can be as little as four weeks. We leverage our 30+ years of experience to help our clients be as successful as possible.

Ultem
Good material for structural components that require strength and rigidity at elevated temperatures.

Why choose Ultem?
- Flame resistant
- UV stable
- FDA compliant
- High electrical insulation properties
- Good performance at elevated temperatures
What are some common Ultem applications?
- Medical devices
- Aircraft components
- Electronics
- Food processing equipment
- Automotive components
Ultem has excellent heat and flame resistance, performing continuously to 340° F. It is hydrolysis resistant and highly resistant to acidic solutions; it can easily tolerate repeated steam sterilizations for reusable medical devices. Ultem is also used in electronics because of its good arc resistance and is well-suited to applications that require consistent dielectric properties over a wide range of frequencies.
Controlled Fluidics uses several varieties of Ultem, including:
- Ultem 1000 plate 0.100” – 3” thick
- Ultem 1000 rod up to 4’’ diameter
- Ultem 2300 rod up to 3” diameter
- Ultem 2300 plate 0.250” – 4” thick
