Ultem finds applications in various industrial settings. It is employed in chemical processing equipment due to its exceptional resistance to a wide range of chemicals, including acids, bases, and solvents. Additionally, it is utilized as electrical insulation for industrial machinery, where its high temperature resistance and robustness are valuable. Ultem's ability to withstand harsh environments and maintain its mechanical and electrical properties make it well-suited for industrial applications.

In addition to 2-component injection molding, it is also possible to process three types of plastic into one plastic part. This is called 3K injection molding.

In the Transition Agenda for Plastics, we have jointly set ourselves the goal that by 2050 the extraction of new raw materials will take place

Ultem's compatibility with sterilization methods, such as autoclaving and gamma irradiation, makes it well-suited for medical and healthcare applications. It is widely used in surgical instruments, medical device housings, and components that require good chemical resistance and durability. Its ability to withstand repeated sterilization cycles without degradation ensures the maintenance of stringent hygiene standards in medical settings.

The chemical bonding process involved in this happens because they are capable of joining two or more materials into one part. When using a 2K injection molding technology process, the choice of material will be the most important factor for the project’s success. Two completely opposite polymers can be used for a ready-to-use product.

Ultem is a trademarked name for the group of thermoplastic materials known as polyetherimides. It was developed by General Electric's Plastics Division (now SABIC) and has become a leading choice for engineers and manufacturers worldwide. Ultem is known for its outstanding mechanical properties, excellent dimensional stability, and resistance to chemicals and high temperatures.

Based on polyetherimide resin, Ultem can be vulnerable to stress cracking when exposed to polar chlorinated solvents. This limitation requires careful consideration of chemical compatibility and may restrict its use in certain applications.

Ultem is compatible with various sterilization methods, including autoclaving, gamma irradiation, and ethylene oxide (ETO) sterilization. This makes it suitable for applications in the medical and healthcare industry, where sterilization is crucial.

A disadvantage of 2K injection molding is that the costs for a mold are higher than a mold for 1K injection molding. Furthermore, the injection molding machine must be equipped with a second plastic component, which also makes the machine more expensive. Ultimately, with 2K injection molding, the costs are recovered by reducing labor and assembly costs, because the manual application of, for example, a seal is no longer necessary. This avoids an assembly step.

The choice of material is very important, as different plastics have different physical properties. The plastics that are processed together must be compatible with each other and the difference in shrinkage of the two plastics should be small.

Improper control during manufacturing processes can lead to surface defects or dimensional instability in Ultem plastic parts, requiring careful attention to quality control measures.

Ultem Plastic, possesses a range of exceptional properties that make it a preferred choice in various industries. Let's explore its key properties as below:

The raw material granulate granules are supplied in a wide variety of types, colors, and designs. In order to influence properties or color, the producer

As a type of polyetherimide plastic, Ultem plastic is widely used across various industries due to its unique characteristics. Let's explore the common applications of its:

Ultem plastic tends to be more expensive compared to other engineering thermoplastics, which can impact overall project costs.

Ultem is extensively employed in electrical and electronic applications due to its excellent electrical insulation properties. It is commonly used in connectors, sockets, circuit boards, and various insulating components. Its high dielectric strength ensures reliable insulation and prevents electrical current leakage, making it ideal for ensuring the safe and efficient operation of electrical and electronic systems.

Ultem possesses outstanding electrical insulation properties. It has high dielectric strength and good electrical insulation capabilities, making it suitable for electrical and electronic applications. This property ensures reliable insulation, preventing electrical current leakage and maintaining proper electrical performance.

Ultem plastic requires molds to be heated during the injection molding process, adding complexity and potentially increasing production costs.

Ultem plastic has a high melting point and viscosity, making it more difficult to process and fabricate. Specialized equipment and expertise may be required for optimal results.

Ultem is also used in the manufacturing of consumer goods. Its lightweight nature, durability, and resistance to heat and chemicals make it a preferred choice for a variety of consumer products. It finds application in household appliances, sports equipment, consumer electronics, and other products where reliability and performance are essential.

Ultem demonstrates remarkably dimensional stability, meaning it maintains its shape and size even when exposed to mechanical stress or temperature variations. It has low creep, which is the tendency of a material to deform over time under constant stress. This property ensures that components made from Ultem retain their intended dimensions and functionality over extended periods.

Ultem is highly valued in aerospace and automotive industries where lightweight materials with exceptional strength and thermal stability are crucial. It finds use in a range of components, including aircraft interiors, automotive engine parts, electrical connectors, and lighting systems. Its ability to withstand high temperatures and maintain mechanical properties makes it a wonderful choice for these demanding applications.

2K injection molding is a production process in which two materials (colors) are processed in one plastic part. This plastic molding technology combines two materials or two different color materials into one ending plastic part using a 2K injection molding machine.

Ultem exhibits outstanding mechanical strength, making it suitable for applications that require robust materials. It has high tensile strength and excellent resistance to impact and deformation. Even at elevated temperatures, Ultem retains its mechanical properties, ensuring structural integrity under harsh conditions.

The 2K injection molding process is mainly used for products that have to meet several special function or appearance requirements. For example, some products must be waterproof, drop-resistant, and dust-proof. Other products must have a variety of colors on the surface to meet aesthetic requirements. Some products may also require a good grip and touch. This includes realizing effects such as a soft-touch surface, an ergonomic design, a two-tone appearance, watertightness of a product, shock absorption, moisture resistance or making plastic parts anti-slip.

Ultem is composed of polyetherimide resin, which is a high-performance polymer. This resin is characterized by its good thermal stability, high strength, and exceptional chemical resistance. It retains its mechanical properties even at elevated temperatures, making it suitable for applications that demand structural integrity under harsh conditions.

Another disadvantage of 2K injection molding is that it makes the recycling of the plastic products difficult, because often two different plastics are combined. Even when the plastics are “from the same family”, the quality of return flows will be less. This makes it difficult to reuse the plastics for a high-quality application.
