Processing Guidelines (Injection Molding)

Critical Processing Warnings:

• Drying: ULTEM DT1810EV is hygroscopic and must be dried to <0.02% moisture before processing. Dry at 150°C for 4-6 hours.

• High Flow & Internal Mold Release: This grade offers high flow characteristics (MFR 43 g/10min, MVR 56 cm³/10min) and contains internal mold release agents for improved demolding and processing efficiency.

• Melt Temperature: Recommended melt temperature range is 325-350°C.

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

• 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.

• Optical Applications: For optical components, ensure clean processing conditions to maintain optical clarity and IR transmission properties.

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