ULTEM JD7904 – Conductive Anti-Static PEI Resin by SABIC

ULTEM Resin JD7904 is a conductive, carbon powder filled polyetherimide (PEI) resin manufactured by SABIC. As an authorized distributor and trader, we supply genuine SABIC materials with full traceability. For more product options and company information, please visit our website at https://szrqchem.com/.

ULTEM JD7904 is a non-reinforced, electrically conductive PEI resin formulated with conductive carbon powder to provide anti-static and anti-dusting properties. Unlike JD7903 which contains 10% glass fiber reinforcement, JD7904 is non-reinforced, offering a different balance of properties for applications where glass fiber is not required.

Key attributes include:

• Electrically Conductive – Formulated with conductive carbon powder; surface resistivity of 1.0×10¹⁰ Ω for effective static dissipation and anti-dust performance

• Good Strength & Stiffness – Tensile strength of 84 MPa; flexural modulus of 3,720 MPa; flexural strength of 127-128 MPa

• Inherent Flame Retardancy – UL94 V-0 (0.41mm) rating; limiting oxygen index (LOI) of 47%

• Excellent Dimensional Stability – Low shrinkage of 0.50-0.70%

• Broad Chemical Resistance – Retains strength when exposed to automotive fluids, aircraft fluids, aliphatic hydrocarbons, alcohols, acids, and weak aqueous solutions

• Low Smoke & Toxicity – Products of combustion no more toxic than wood

• Good Processability – Suitable for injection molding; good flow ability

• RoHS Compliant – Supports environmentally responsible material selection

• PFAS-Free – No PFAS intentionally added during manufacturing

• Versatile Processing – Suitable for injection molding, extrusion, thermoforming, and blow molding

Key Features of ULTEM JD7904

• Broad Chemical & Hydrolytic Stability – Retains strength and resists stress cracking when exposed to automotive and aircraft fluids, aliphatic hydrocarbons, alcohols, acids, and weak aqueous solutions

• Low Smoke & Low Toxicity – Inherently low smoke; products of combustion no more toxic than wood

• Dark Opaque Appearance – Reflects the presence of conductive carbon fillers; optimized for functional performance rather than optical clarity

• Good Processability – Suitable for injection molding, extrusion, thermoforming, and blow molding; good flow ability allows long flow lengths

• RoHS Compliant – Supports environmentally responsible material selection

• PFAS-Free – No PFAS intentionally added during manufacturing

• Non-UL Rated – Formulation focused on conductivity and functional performance; not UL rated

Typical Applications for ULTEM JD7904

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 JD7904 is hygroscopic and must be dried to <0.02% moisture before processing. Dry at 150°C for 4-6 hours.

• Melt Temperature: Recommended melt temperature range is 380-410°C. Avoid excessive residence times to prevent thermal degradation.

• Mold Temperature: Higher mold temperatures (140-170°C) improve flow and reduce residual stress.

• Carbon Powder Content: This grade contains conductive carbon powder. Proper handling and processing conditions are recommended to achieve optimal surface finish and electrical properties.

• 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.

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