Processing Guidelines (Injection Molding)

Critical Processing Warnings:

• Drying: ULTEM EXUM0167 is hygroscopic and must be dried to ≤0.02% moisture before processing. Dry at 135°C for 4-6 hours.

• Internal Mold Release: This grade contains internal mold release agents for improved demolding and processing efficiency.

• Melt Temperature: Recommended melt temperature range is 330-355°C.

• 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.

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