Typical Applications for ULTEM DU242

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 (Injection Molding)

Critical Processing Warnings:

• Drying: ULTEM DU242 is hygroscopic and must be dried to ≤0.02% moisture before processing. Dry at 135°C for 4-6 hours (cumulative up to 12 hours).

• High Flow: This grade offers high flow characteristics (MFR 30 g/10min) for easier processing and better mold filling of complex, thin-walled parts.

• Melt Temperature: Recommended melt temperature range is 330-355°C. Nozzle temperature should be 325-350°C.

• Mold Temperature: Higher mold temperatures (95-135°C) improve flow and reduce residual stress.

• Electroplating: This grade is specifically formulated for electroplating applications.

• 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.

• PFAS-Free: This product does not contain PFAS intentionally added during manufacturing.
