Typical Properties

Important Notes on Typical Data:

• Values listed are typical and sourced from SABIC official data sheets. They do not constitute binding product specification.

• Batch-to-batch deviations may exist. For critical applications, validate performance with batch-specific COA certificate.

• Final performance depends on processing conditions, mold design, and part geometry.

• SABIC official TDS shall serve as definitive technical reference. Request the latest official TDS from our sales team.

Processing Guidelines (Injection Molding)

Critical Processing Warnings:

• Drying: ULTEM 4211 is hygroscopic and must be dried to <0.02% moisture before processing. Dry at 135°C for 4-6 hours.

• Melt Temperature: Recommended melt temperature range is 349-371°C. Avoid excessive residence times to prevent thermal degradation.

• Mold Temperature: Higher mold temperatures (135-163°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.

• Wear Applications: This bearing grade is specifically formulated with PTFE for low friction and wear resistance. Optimal performance is achieved with proper surface finish and operating conditions.
