Polyetherimide Thermoplastic Material at Aline Components Custom Plastic Injection Molding and Manufacturing Company

Need a custom injection molded plastic part that is suitable in high strength/high heat applications? Aline Components has the thermoplastic material you need to make your end product or subsystem run smoothly, efficiently, and accurately for a long service life. A premier plastic injection molding and manufacturing company located in Kulpsville, PA, Aline Components utilizes the finest polyetherimide (PEI) resins to custom fabricate components that require long-term high strength and rigidity at elevated temperatures.

At Aline Components, polyetherimide is available in transparent and opaque colors as well as glass-filled grades upon request. FDA and USP Class VI compliant colors are available on a custom basis. We work directly with some of the most reputable resin suppliers in the business and feature General Electric’s Ultem® family of polyetherimide resins. Whether you need standard or glass-filled formulations, Aline Components provides customers based internationally, nationally, and regionally in Pennsylvania, New Jersey, Delaware, and Maryland with custom plastic parts or components that exhibit a higher level of heat resistance, chemical resistance, dielectric strength, and much more.

What is Polyetherimide Thermoplastic Material?

Pure polyetherimide (PEI) is an amber transparent, amorphous high performance polymer. Ultem® is a transparent polymer with an amber hue. Rods and sheets composed of polyetherimide plastic are typically dark, almost black in appearance and glass filled formulations appear slightly less dark, almost caramel in color. What allows PEI to perform continually in high heat applications is its ability to maintain its strength up to 200°C while unfilled, transparent grades are equal in strength to other thermoplastic materials with opacifying fillers.

Polyetherimide Plastic Properties

Inherently flame resistant and low smoke generating, Ultem® polyetherimide excels in various medical applications that require repeated sterilization, as well as structural applications that require a tolerance for high heat. Polyetherimide is a uniquely balanced thermoplastic material that exhibits both high mechanical properties and processibility. Some of its mechanical properties include a remarkable elevated thermal resistance, high dielectric strength and stiffness, and a broad chemical resistance. Easy processibility allows the designers at Aline Components’s flexibility and freedom in plastic injection molding and manufacturing.

Advantages of Polyetherimide Plastic Include:
  • High dielectric strength
  • Excellent flame and heat resistance
  • Extremely low smoke generation 
  • Resistance to environmental stress and cracking
  • Outstanding hydrolysis and acidic solution resistance
Benefits of Polyetherimide

Due to the high dielectric strength and rigidity at elevated temperatures, Aline typically machines injection molded plastic parts or components for analytical instrumentation, electrical insulators, and much more. Ultem® is exceptionally difficult to ignite and meets various specifications including, but not limited to UL94 V0. This thermoplastic material generates low smoke with combustible parts no more toxic than wood.

When compared to other amorphous thermoplastics, polyetherimide resins retain strength and resist stress and cracking better in extremely demanding environmental conditions. Exposure to automotive and aircraft fluids, alcohols, aliphatic hydrocarbons, acids, and weak aqueous solutions pose no challenge for plastic injection molded parts or components manufactured by Aline Components. We are a plastic injection molding and manufacturing company and suggest using Ultem® polyetherimide when well above average performance is required.
