ULTEM CRS5011R – Enhanced Flow Chemical Resistant PEI Resin with Internal Mold Release

ULTEM Resin CRS5011R is an enhanced flow, transparent polyetherimide (PEI) copolymer manufactured by SABIC. As an authorized distributor and trader, we supply genuine SABIC materials with full traceability.

This grade is specifically engineered for applications requiring superior chemical resistance to strong acids, bases, aromatics, and ketones while offering enhanced flow and internal mold release for improved processing efficiency. It is a PFAS-free, amorphous, flame retardant PEI copolymer ideal for harsh chemical environments where standard engineering plastics may degrade.

ULTEM CRS5011R is also a preferred material for eyewear frames and AR/VR glasses, delivering high strength-to-weight ratio for thin wall, lightweight designs. Its inherent flame retardancy eliminates the need for additional FR agents, which can cause materials like amorphous nylon to become brittle. The material adheres to IEC62368-1 electronic safety standards and meets JIS B7285 for eyewear applications (including 20,000 cycles blending repetitions).

Processing Guidelines (Injection Molding)

Critical Processing Warnings:

• Drying: ULTEM CRS5011R is hygroscopic and must be dried to <0.02% moisture before processing. Dry at 150°C for 4-6 hours.

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

• Enhanced Flow: This grade offers enhanced flow characteristics (MFR 11 g/10min, MVR 20 cm³/10min) compared to standard flow grades, enabling easier processing and better mold filling of complex parts.

• Melt Temperature: Recommended melt temperature range is 365-390°C. Avoid excessive residence times to prevent thermal degradation.

• Mold Temperature: Higher mold temperatures (135-165°C) improve flow and reduce residual stress.

• Chemical Resistance: This grade is formulated for enhanced chemical resistance to strong acids, bases, aromatics, and ketones. Verify compatibility with specific chemicals in your application.

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

• 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.
