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. FDA compliant grades of Ultem® are available.
What is ULTEM made of?
The ULTEM™ resin family of amorphous thermoplastic polyetherimide (PEI) materials offers outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. ULTEM resins are available in transparent and opaque custom colors, as well as glass filled grades.
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.
Is ULTEM impact resistant?
ULTEM™ 9085 is primarily characterized by very high mechanical strength and impact resistance, with a high strength to weight ratio. The tensile strength is 70 MPa and elongation at break is approx. 5,3%. The impact strength of the material is approx.
What kind of 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.
What is Ultem frame?
Ultem glasses are also called PVC glasses and PEI glasses. They belong to plastic frames, whose frames are made of amorphous PEI. This kind of material has perfect ductility and lightweight which is one third of traditional plastic and metal frames.
What temp does ULTEM melt?
Ultem 1000 (Polyetherimide) Specification Test Value Continuous Service Temperature in Air 340 Short Term Service Temperature 360 Tg-Glass Transition (Amorphous) D3418 410 Melting Point (Crystalline) Peak D3418.
Is ULTEM heat resistant?
Ultem® is resistant to hot water and steam and can withstand repeated cycles in a steam autoclave. FDA compliant grades of Ultem® are available. Tech Tip– Ultem® is often used instead of polysulfone when superior strength, stiffness, or temperature resistance is required.
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.
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.
Can you mold Ultem?
This premium quality plastic material is resistant to hot water and steam and can withstand repeated cycles in a steam autoclave. Ultem™ molding is a less expensive alternative to high-end PEEK plastic material. Ultem™ is a highly-effective injection molding plastic.
Can Ultem be 3D printed?
Existing certifications: ULTEM™ resin is FST rated and one of the only 3D printing plastics certified for aircraft components. In the aerospace industry, most parts are required to have this rating to ensure the flame, smoke and toxicity (FST) resistance of a material.
What color is Ultem?
The standard color of Ultem (unfilled) stock shapes is light amber. Glass filled grades appear tan or greenish in color.
Is Ultem an insulator?
Ultem has high heat resistance, UV and gamma radiation resistance and high strength and modulus as well as excellent electrical insulating properties.
Is Ultem a good material for glasses?
ULTEM- Ultem is an amorphous thermoplastic polyetherimide (PEI) material which has extraordinary properties perfect for eyeglass frames.
Which frame material is best for sunglasses?
In general, frames made from metal, titanium or alloys (a mixture of metals) stand up well to wear and tear. Titanium frames are very strong, lightweight and corrosion-resistant. Monel is a mixture of metals. Beryllium costs less than titanium, and is very lightweight and strong.
What is tr100 material?
These trendy eyeglasses are made from TR-100, kind of memory plastic, extremely flexible and durable. The frames can restore their original shapes even after bending, twisting and crushing. These sporty and fashionable glasses are similar to the Nike sports glasses.
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.
Is PEI the same as Ultem?
Ultem. Ultem is a family of PEI products developed by Joseph G. Wirth at General Electric in the early 1980s. Since its acquisition of the GE Plastics Division in 2007, Ultem is manufactured by SABIC.
Is Ultem hydrophobic?
Ultem® is chosen as the inner support layer because of its good mechanical strength, slight hydrophilicity, and moderate compatibility with PVDF [26], [27], while PVDF is selected as the outer separation layer due to its hydrophobicity.
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.
Is Ultem a thermoplastic?
ULTEM™ 9085 resin is a flame-retardant, high-performance thermoplastic. It features a high strength-to-weight ratio, excellent heat resistance and high impact strength.
What is high temperature plastic?
High-temperature plastics are typically classified as materials that can exceed 250° F in continuous operating temperature (aka continuous service temperature). These materials include products such as Vespel®, Torlon®, PEEK, Teflon®, Meldin®, Celazole® & Macor®. Some of these materials exceed 300° CST.
Why is PEEK so expensive?
Why is PEEK So Expensive? The price point for PEEK (polyetherketone) often comes as a surprise to clients. However, these other polymers can’t compete with the advanced properties of PEEK. PEEK is commonly used to produce high-quality plastic parts that electrically and thermally insulating, as well as thermostable.
Is Ultem 1000 glass filled?
ULTEM™ 1000 – is an amber transparent high-performance unfiled PEI polymer which combines high strength and rigidity at elevated temperatures with long term heat resistance. ULTEM™ 2100 – is a 10% glass filled PEI grade with improved rigidity and stiffness.
What is PEEK filament?
PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. PEEK is regarded as one of the highest performing engineering thermoplastics in the world together with other polymers of the PAEK family such as PEKK.
