Processing Guidelines (Injection Molding)

Critical Processing Warnings:

• Drying: ULTEM LTX300A is hygroscopic and must be dried to <0.02% moisture before processing. Dry at 135°C for 4-6 hours.

• High Flow: This grade offers high flow characteristics (MVR 15 cm³/10min) for easier processing and better mold filling of complex, thin-walled parts.

• Thin Wall Molding: Capable of molding down to 1.2 mm.

• 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.
