What Is Ultem

What kind of material is Ultem?

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 used for?

Ultem® is widely used in electronics because of its good arc resistance and dielectric constant. Other typical applications include analytical instrumentation and structural components that require high strength and rigidity at elevated temperatures.

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 toxic?

Oral Toxicity: Ultem resins have very low acute oral toxicity. Fume Inhalation: Processing fumes from typical Ultem resins are not considered toxic.

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.

Can ULTEM be injection molded?

Like all PEI materials, Ultem™ is similar to PEEK, but with lower impact strength and a lower useable temperature. This premium quality plastic material is resistant to hot water and steam and can withstand repeated cycles in a steam autoclave. Ultem™ is a highly-effective injection molding plastic.

Can you autoclave ULTEM?

ULTEM™ 1010 resin is autoclave-capable, making it suitable for composite lay-up tooling.

What is the melting point of ULTEM?

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.

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.

Is Ultem a thermoplastic?

ULTEM®, the branded name for polyetherimide (PEI), is one of the few commercially available amorphous thermoplastic resins that retains its mechanical integrity at high temperatures.

Who invented Ultem?

Ultem is a family of PEI products developed by Joseph G. Wirth at General Electric in the early 1980s.

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.

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.

Is Ultem a good material for glasses?

ULTEM- Ultem is an amorphous thermoplastic polyetherimide (PEI) material which has extraordinary properties perfect for eyeglass frames.

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.

What are acetate glasses?

Acetate is a type of nylon-based plastic, so acetate frames are similar to plastic ones in a lot of ways. Acetate can best be described as an exceptionally strong, hypoallergenic and flexible type of plastic, making it ideal for eyeglass frames you can wear comfortably all day long.

Can you put plastic in an autoclave?

Make sure your plastic bag or container is suitable, since not all plastics can be autoclaved (i.e., polyethylene or HDPE). They can melt and ruin the autoclave chamber. Autoclave bags are tear resistant, but can be punctured or burst in the autoclave.

What is autoclave material?

Generally, the only type of glass that you should be placing in an autoclave is Pyrex or Pyrex type materials. As a general rule of thumb, you should never autoclave liquids in a closed container. Polypropylene. Polypropylene is an inexpensive resin that is capable of withstanding autoclaving temperatures.

Can nylon be autoclaved?

Polypropylene is an inexpensive resin that can resist autoclave temperatures. Polystyrene (PS), polyvinyl chloride (PVC), nylon, acrylic, low-density polyethylene (LDPE), and high-density polyethylene (HDPE) lab ware and polyurethane tubing are not autoclavable under any conditions.

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.

What is the density of Ultem?

1.27 g/cm³.

Is Pei machinable?

ULTEM PEI (polyetherimide) is a high-strength amorphous polymer. PEI has more than just excellent heat and flame resistance. There’s more than one particular type of ULTEM PEI you can machine, and each has slightly different properties for perfecting this material’s use in different applications.

What does PEI stand for 3D printing?

3D Printing Platform (Made in the USA) PEI (Polyetherimide) is a great building surface for any 3D printer. The amber / yellow colored surface is commonly used to print a whole range of different filament types such as the two most commonly used ones, ABS and PLA.

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 Ultem 3D printing?

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. It’s also possesses favorable flame, smoke and toxicity (FST) characteristics.

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 color is Ultem?

The standard color of Ultem (unfilled) stock shapes is light amber. Glass filled grades appear tan or greenish in color.

How is PEEK made?

Synthesis of PEEK requires accurate reaction conditions because of its insolubility. PEEK can been synthesized by using nucleophilic substitution of 4,4′ – difluorobenzophenone with hydroquinone in the presence of anhydrous potassium carbonate under microwave irradiation to produce a good yield.
