ULTEM 4001 – PTFE Filled Bearing Grade PEI Resin by SABIC

ULTEM Resin 4001 is a PTFE filled, bearing-grade polyetherimide (PEI) engineering thermoplastic manufactured by SABIC. As an authorized distributor and trader, we supply genuine SABIC materials with full traceability.

ULTEM 4001 is a standard flow, internally lubricated grade specifically formulated for wear-resistant bearing and sliding applications without glass reinforcement. The PTFE modification provides self-lubricating properties, enabling reduced coefficient of friction and improved wear resistance for components operating in sliding and dynamic contact systems. Key attributes include:

• PTFE Internal Lubrication – PTFE modification provides self-lubricating properties and reduced coefficient of friction (0.25 vs steel dynamic)

• Excellent Wear Resistance – Taber abrasion of only 2 mg/1000 cycles (CS-17, 1 kg)

• High Heat Resistance – Glass transition temperature (Tg) of 217°C

• Inherent Flame Retardancy – UL94 V-0 (0.38mm) and 5VA (1.5mm) ratings without additional flame retardant modifiers

• High Strength & Stiffness – Tensile strength of 103 MPa; flexural modulus of 3,000-3,350 MPa

• Good Dimensional Stability – Low creep sensitivity and low shrinkage (0.50-0.80%)

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

• Low Smoke & Toxicity – Suitable for aerospace and mass transit applications

• Good Processability – Consistent flow characteristics for efficient manufacturing of complex geometries

• ECO Conforming & RoHS Compliant – Meets environmental compliance standards

• Versatile Processing – Suitable for injection molding; capable of long flow lengths

Typical Applications for ULTEM 4001

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 4001 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 for low friction and wear resistance. The non-reinforced structure supports better surface finish and reduced abrasion on mating components.
