What type of plastic is Ultem?
polyetherimide
Ultem® (polyetherimide) is a semi-transparent high strength plastic material that can operate in high service temperature environments. Ultem® is resistant to hot water and steam and can withstand repeated cycles in a steam autoclave.
How expensive is Ultem?
PEEK generally costs around $500 per kilo, whereas Ultem costs around $250 — though this can vary. PPSU is similar to PEI in that it is a similar material that is also amorphous, but offers better impact and chemical resistance than Ultem.
What polymer is Ultem?
Ultem® / PEI (polyetherimide) is a high-strength amorphous polymer with excellent heat and flame resistance (carrying a flammability rating of 94-V-0) with little smoke output. It performs continuously to 340° F, making it superior to commodity plastics such as Nylon and Delrin®.
Where is Ultem used?
Often used in the production of circuit boards, eyeglasses, food preparation and sterilization equipment, and, perhaps most notably, aircraft parts, ULTEM is known for its strength and durability.
Is Ultem toxic?
Oral Toxicity: Ultem resins have very low acute oral toxicity. Fume Inhalation: Processing fumes from typical Ultem resins are not considered toxic.
Can you autoclave Ultem?
ULTEM™ 1010 resin is autoclave-capable, making it suitable for composite lay-up tooling.
Is Ultem brittle?
While Ultem® is also resistant to a broad spectrum of chemicals, its brittle nature makes it more prone to environmental stress cracking.
What is the melting point of Ultem?
Ultem 1000 (Polyetherimide)
| Specification | Test | Value |
|---|---|---|
| Tg-Glass Transition (Amorphous) | D3418 | 410 |
| Melting Point (Crystalline) Peak | D3418 | |
| Thermal Conductivity | F433 | 0.9 |
| Dielectric Strength Short Term | D149 | 830 |
How strong is ULTEM?
ULTEM’s tensile strength is 15,200 psi and it has a flexural modulus of 480,000 psi. It has very high heat resistance, maintaining most of its physical properties in temperatures as high as 170°C.
Is ULTEM an insulator?
As mentioned previously, ULTEM is a highly sought-after thermoplastic for weight-saving capabilities in aerospace components to reusable autoclave sterilizations in medical applications. However, it’s most commonly used in high voltage electrical insulation applications. Common uses include: Electrical Insulators.
Who invented Ultem?
Joseph G. Wirth
Ultem is a family of PEI products developed by Joseph G. Wirth at General Electric in the early 1980s.
Is Ultem a polycarbonate?
SEMI-TRANSPARENT Ultem – Polysulfone – Polycarbonate The ULTEM family of amorphous thermoplastic polyetherimide (PEI) materials offer outstanding thermal resistance, high strength and stiffness. Ultem also has broad chemical and excellent steam resistance.
What are the properties of the plastic Ultem?
Ultem® (polyetherimide) is an extremely strong and stiff semi-transparent plastic that can operate in high service temperature environments. Resistant to hydrolysis when exposed to hot water and steam, Ultem® can withstand repeated sterilization cycles in a steam autoclave.
What kind of resin is the Ultem resin?
General Information. Description. The ULTEM Resin family of amorphous thermoplastic polyetherimide (PEI) resins offers outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. ULTEM is available in transparent and opaque custom colors, as well as glass filled grades.
When was the invention of the Ultem made?
Initially developed by General Electric Plastics Division (now SABIC) in the early 1980s, ULTEM is a high-performance plastic that has been a staple of the manufacturing industry for over 35 years.
Why are Ultem polyetherimides used in medical devices?
The product also suits applications that require consistent dielectric properties over a wide range of frequencies. Ultem® is hydrolysis resistant and highly resistant to acidic solutions and is able to tolerate repeated autoclaving cycles, such as with repeated steam sterilization of reusable medical devices.
