SABIC ULTEM™ 2310: Why is this PEI called the "All-Round Ace" of high-performance injection molding?

In the precision injection molding industry, as demands for high-temperature resistance, high strength, and flame retardancy of components continue to rise, selecting the right specialty engineering plastic determines a product's core competitiveness in demanding applications. One specialty resin from SABIC has earned high praise among high-end procurement circles and engineering communities in recent years – SABIC ULTEM™ 2310.

I. Prestigious Origin: SABIC and the Quality Assurance of the ULTEM™ Series

SABIC is a world-class chemical giant, and its ULTEM™ series of polyetherimide (PEI) resins are widely recognized as a benchmark for high-performance specialty engineering plastics. SABIC ULTEM™ 2310 resin is a 30% glass fiber-reinforced polyetherimide material featuring excellent flowability.

Simply put: It perfectly inherits the inherent outstanding high-temperature resistance, high strength, and high rigidity of PEI materials, while significantly enhancing mechanical properties through 30% glass fiber reinforcement. At the same time, its optimized flow design solves the common problems of traditional high-performance specialty engineering plastics – narrow processing windows and difficult mold filling.

II. Hard Data: 4 Key Performance Highlights of SABIC ULTEM™ 2310

Let's look directly at the official technical datasheet (typical values):

1. Melt Flow Rate: Melt Mass-Flow Rate (MFR, 337°C/6.6kg) is approximately 7.1-8.0 g/10min. For a material with up to 30% glass fiber reinforcement, this represents excellent flowability. This means that when molding complex thin-wall or long-flow-length precision parts, the material can fill the cavity completely, greatly reducing the risk of short shots.

2. Tensile Strength & Modulus: Tensile yield strength can reach 169 MPa, and flexural modulus is as high as 9500 MPa. These values far exceed those of ordinary engineering plastics, ensuring that parts maintain outstanding rigidity under long-term stress without creeping or deforming. This makes it particularly suitable for metal-replacement structural applications.

3. Superb Thermal Performance: The glass transition temperature is as high as 217°C, and the heat deflection temperature (1.82 MPa) reaches 210-220°C. The material can be used continuously over a wide temperature range from -160°C to 180°C. It also possesses inherent flame retardancy with UL94 V0 and 5VA ratings, requiring no additional flame retardant additives.

4. Excellent Dimensional Stability: Linear mold shrinkage is extremely low, typically between 0.2% and 0.6%. This is far superior to commodity plastics, ensuring dimensional precision and stability for precision-fit parts and long-term thermal cycling.

One-sentence summary: Ultra-high strength + Outstanding heat resistance + Inherent flame retardancy + Dimensional stability – all in one.

III. Applications: What pain points can SABIC ULTEM™ 2310 solve?

Thanks to its outstanding combination of properties, this material is an undisputed solution in a variety of high-end application scenarios.

• Medical & Laboratory Consumables: Suitable for surgical instrument trays, dental instrument handles, analytical test fixtures, drug delivery system components, etc. Beyond its excellent mechanical strength and dimensional stability, the medical-grade version (HU2310) offers biocompatibility certifications (e.g., ISO 10993 or USP Class VI) and can withstand various aggressive sterilization methods including steam, EtO, and gamma radiation.

• Electronics, Electrical & Semiconductor: High-temperature connectors, relay bases, coil bobbins, wafer trays, high-insulation components, etc. Leveraging its heat deflection temperature exceeding 200°C, excellent electrical insulation properties, and inherent V0 flame retardancy, the material ensures long-term stable operation under heat and high voltage, providing electrical safety and reliability.

• Automotive, Aerospace & Industrial Components: Automotive sensor housings, transmission components, aircraft interior parts, high-temperature lamp sockets, semiconductor process fixtures, and more. These applications demand materials that can withstand high temperatures, chemical exposure, and continuous mechanical stress. The high strength, high modulus, and thermo-oxidative stability of SABIC ULTEM™ 2310 make it a key metal-replacement material, enabling lightweighting and performance enhancement.

In short: For any injection-molded part requiring long-term high-temperature resistance, high strength, high rigidity, precision dimensions, and flame retardancy – especially in cutting-edge industries like medical technology, aerospace, semiconductor equipment, and automotive electronics – SABIC ULTEM™ 2310 is truly the "All-Round Ace" of reliable performance.
