In a previous post, we explored the advantages of Sabic Ultem™, the trademarked name for a special type of high-performance plastic that is often the go-to choice for any industry in need of exceptional physical properties in a thermoplastic. With Ultem™ polyetherimide resins, this type of plastic can retain its mechanical properties even at extremely high temperatures, which is especially important in applications that require good structural integrity under harsh conditions–aerospace and automotive applications for example.
Why is ULTEM™ so popular?
This material is known for its excellent mechanical properties, dimensional stability, as well as chemical and temperature resistance. Because of these properties, Ultem™ has been used widely and with success in many different industries, such as aerospace, automotive, consumer goods, medical equipment, electronics, and industrial equipment. There are, however, a few disadvantages to keep in mind when deciding whether or not to use Ultem™ for your manufacturing project.

A few disadvantages of using ULTEM™
Also, the polyetherimide thermoplastic can be vulnerable to stress cracking if exposed to polar chlorinated solvents. This can restrict its use in certain applications.
In addition, while Ultem™ is a very high performance thermoplastic, it does tend to be more expensive compared to similar materials and can be difficult to process due to its high melting point and viscosity. For optimal results, you may need to use specialized equipment or work with someone specialized in working with this thermoplastic, which could drive up production costs even more. If the material is not properly controlled during manufacturing, Ultem™ plastic parts can experience surface defects or cracks as well as dimensional instability. If large amounts of material are removed during machining, parts should be annealed after production to prevent warp and twist. Proper quality control needs to be in place to avoid these problems.

The quick answer is: the opposite of single use plastic.
Performance plastics are a wide range of materials that are designed for use in mechanical, engineering, aerospace, food processing, and many other applications. These performance plastic materials generally have superior physical properties, and frequently are used to replace other materials like metals, wood and glass.
Most performance plastic sheets and rods are machinable, and can be used to replace other substrates that can not stand up to the same demanding applications that these performance plastics can. Performance plastics are the natural choice when considering replacement for traditional materials, such as bronze, stainless steel, glass, wood and copper, for not just one reason but rather a combination of features and benefits.
Nearly all Performance Plastic grades can be recycled.
Because of their cost-effectiveness as well as their reliability, durability, and special characteristics like resistance to chemicals and corrosion the high performance plastic materials are steadily replacing metals in the oil and gas industry. The constant development of new and better high performance plastics is therefore closely linked to the development and economic production of the range of available performance plastic materials. High performance plastics can be divided in amorphous and semi-crystalline polymers, just like all polymers.

Why use a Performance Plastic?
Performance plastics are designed for repeated or multi-use applications and generate a smaller carbon footprint than glass, steel, or wood. High performance plastics are plastics that can perform well under extreme environments. Because most performance plastics are considered ‘self lubricating’, these materials can be made into parts that replace metals, and don’t require the continual maintenance and lubrication that metals require.
Over the past few decades Mechanical Plastics have increasingly replaced metals due to their strength-to-weight ratios, and resistance to wear have surpassed aluminum and steel, respectively. When certain additives are blended with thermoplastic polymers, this performance plastic can meet code and compliance requirements for smoke, flammability, and even toxic gas release. Several high end performance plastics can meet the stringent FM-4910 flame and smoke rating.
Performance Plastic materials are not ‘cheap’
As opposed to ‘single use’ plastics, the performance plastic materials are not inexpensive or ‘throw away’. Rather these high performance materials are designed for specific applications, and out perform most other substrates. Other characteristics of high performance plastics can be extraordinary resistance to wear and tear, high purity or particular electrical insulation. High performance plastics are plastics that can perform well under extreme circumstances. High performance plastics are best known for their temperature, chemical and wear resistance.
Performance Plastics offers high performance plastics for high performance applications, at economical prices, made by quality American made engineering plastics manufacturers. High-performance plastics are formulated to operate under extreme chemical, high temperature and heavy load applications or any combination of these. Most performance plastics are used where the highest demands are placed on thermal or chemical resistance, product mechanics, or on the self-lubrication of products. Several of our key North American suppliers are: Ensinger Plastics, Rochling Plastics, Z/L Engineering Plastics, Simona-America, Plaskolite, and many more.
In the performance plastic market, one size does not fit all. With over 50 high performance plastics, each with its own physical properties, several materials may be proper choices for your performance plastic requirement. Please feel free to call one of our certified and trained customer service personnel for assistance in choosing the best performance plastic for your application.
Polyetherimide or PEI is the generic name for one of the popular engineering resins. The most common resin supplier for this material is Sabic Plastics (formerly known at G.E. Plastics). This amorphous thermoplastic material comes in two common resin varieties used in the production of plastic shapes, the first is Ultem® 1000 which is an unfilled – natural material, the standard color for unfilled PEI (Ultem Sheet) is a transparent amber. The second is Ultem® 2300, which is a 30% glass filled PEI resin, this resin is a creamy tan color. Several other resins are available, including different percentages of glass fill, black pigment or color, and a few high end specialty grades. Some members our our industry refer to Ultem® as the ‘ultimate’ in plastic materials. With some of the best available properties, this material out performs most plastics in critical applications. This material is certified to: FDA compliance, USDA, 3A and also USP Class VI for medical use. Polyetherimides have exceptional tensile and flexural strengths and excellent electrical properties. Ultem® resins have inherent flame resistance and are UL 94 5VA at .075″. Ultem Sheet and rod machines very well, and can be used at temperatures of 340 degrees continuous.
Polyetherimide – PEI is the Ultimate Resin
The Polyetherimide family of plastic resins really excel in the medical and pharmaceutical industries. These industries have incredible demands on plastic materials, and most plastics fail quickly. Ultem resins handle the heat, chemical, stress better than almost any other material. For complete technical data sheets and more information chick for data sheet page. Several of our major manufacturers produce Ultem® PEI resins into stock sheets and rods. Some trade names from these suppliers are: Tempalux®, Sustatec®,Unitem®and many more. Ultem sheet and rod has some of the best properties of all the available plastic materials. Some materials that have some similar properties: Acetal, Radel, PEEK, PTFE. Check the data sheets on each of these materials to help in deciding which material is appropriate for your application.
