Critical Processing Warnings:
-
Drying: ULTEM 2312EPR is hygroscopic and must be dried to <0.02% moisture before processing. Dry at 150°C for 4-6 hours.
-
High Flow: This grade offers excellent flow characteristics (MVR 14 cm³/10min at 360°C/5kg) for easier processing and better mold filling of complex parts.
-
Internal Mold Release: This grade contains internal mold release agents for improved demolding and processing efficiency.
-
Melt Temperature: Recommended melt temperature range is 350-400°C. Avoid excessive residence times to prevent thermal degradation.
-
Mold Temperature: Higher mold temperatures (140-180°C) 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.
-
Electroplating: The EPR grade is specifically optimized for electroplating applications with enhanced metal adhesion.
