Typical Applications for ULTEM 2312

Typical Properties

Important Notes on Typical Data:

• Values listed are typical and sourced from SABIC official data sheets. They do not constitute binding product specification.

• Batch-to-batch deviations may exist. For critical applications, validate performance with batch-specific COA certificate.

• Final performance depends on processing conditions, mold design, and part geometry.

• SABIC official TDS shall serve as definitive technical reference. Request the latest official TDS from our sales team.

Processing Guidelines

Critical Processing Warnings:

• Drying: ULTEM 2312 is hygroscopic and must be dried to <0.02% moisture before processing. Dry at 150°C for 4-6 hours.

• Enhanced Flow: This grade offers improved flow characteristics for easier processing and better mold filling of complex parts.

• Melt Temperature: Recommended melt temperature range is 350-400°C. Avoid excessive residence times to prevent thermal degradation.

• Mold Temperature: Higher mold temperatures (135-165°C) improve flow and reduce residual stress.

• Milled Glass Content: This grade contains 30% milled glass filler, which helps improve stiffness while preserving surface quality.

• Gate Design: Use large gates and runners to minimize flow resistance and reduce molded-in stress.

• Regrind: Regrind can be used up to 20-25% with virgin material, provided it is clean and properly dried.

FAQ

Q1: What is ULTEM 2312 and what is it used for?
A: ULTEM 2312 is a 30% milled glass filled polyetherimide (PEI) resin manufactured by SABIC with enhanced flow. It combines high heat resistance (Tg 217°C), inherent flame retardancy (UL94 V-0 & 5VA), and high stiffness. It is widely used in aerospace interiors, automotive under-hood applications, electrical/electronic components, medical devices, consumer goods, and industrial applications.

Q2: What is the difference between ULTEM 2300 and ULTEM 2312?
A: ULTEM 2300 uses standard glass fiber reinforcement, while ULTEM 2312 uses milled glass fiber reinforcement. Milled glass provides similar stiffness with potentially better surface finish and dimensional stability. Both grades contain 30% glass filler and offer enhanced flow characteristics.

Q3: What is the glass filler content of ULTEM 2312?
A: ULTEM 2312 contains 30% milled glass filler by weight.
