Processing Guidelines (Injection Molding)

Critical Processing Warnings:

• Drying: ULTEM LTX300B is hygroscopic and must be dried to <0.02% moisture before processing. Dry at 135°C for 4-6 hours (maximum 12 hours cumulative).

• Standard Flow: This grade offers standard flow characteristics (MFR 1.6 g/10min) for consistent injection molding processing.

• Mold Temperature: Higher mold temperatures improve flow and reduce residual stress.

• 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.

• Aerospace Compliance: This grade meets FAR 25.853 and OSU 65/65 requirements for aerospace interior applications.

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