Typical Applications for ULTEM 4000

Material Advantages

ULTEM Resin 4000 is a high-performance bearing-grade PEI resin that delivers:

• Self-Lubricating Properties – PTFE and graphite internal lubricants provide reduced coefficient of friction and excellent wear resistance without external lubrication

• Exceptional Wear Resistance – With a Taber abrasion of only 33 mg/1000 cycles, ULTEM 4000 offers outstanding wear resistance for demanding bearing applications

• Low Friction – Dynamic coefficient of friction vs steel of 0.24 minimizes energy loss and heat generation in moving applications

• High Heat Capability – Continuous use up to 170°C (RTI) with a Tg of 217°C, suitable for high-temperature bearing applications

• Inherent Flame Retardancy – UL94 V-0 rating without FR modifiers, ideal for electrical and aerospace applications

• Excellent Dimensional Stability – Ultra-low shrinkage (0.10-0.30%) and low creep for precision bearing tolerances

• Good Chemical Resistance – Resists automotive fluids, aircraft fluids, alcohols, acids, and weak aqueous solutions

• Low Smoke & Toxicity – Exceptionally low smoke and non-toxic combustion products

• Design Flexibility – Can be injection molded, extruded, thermoformed, and blow molded

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

Critical Processing Warnings:

• Drying: ULTEM 4000 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 350-370°C. Avoid excessive residence times to prevent thermal degradation.

• Mold Temperature: Higher mold temperatures (135-165°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 and graphite for low friction and wear resistance. Optimal performance is achieved with proper surface finish and operating conditions.
