ULTEM™ DU319 Non Reinforced, Polyetherimide/ Polycarbonate-Ester Blend

Transparent Colored. Low Temperature High Impact Strength performance

ULTEM™ DU319 PEI Blend Resin introduces a balanced approach to Material Performance by combining Polyetherimide and PET into a Transparent Engineering Solution. Designed for Applications requiring Food Contact Compliance together with reliable Mechanical and Processing Characteristics, ULTEM™ DU319 PEI Blend Resin supports functional Design without unnecessary Material Over-Specification.

Rather than emphasizing Extreme Thermal Capability alone, this Blend focuses on achieving a practical Combination of Strength, Clarity, and Processability. The Material allows Components to maintain Structural Stability while offering improved Toughness compared to traditional PEI Materials, making it suitable for Applications where Performance and Usability must align.

Compliance with U.S. FDA and EU Food Contact Requirements allows ULTEM™ DU319 PEI Blend Resin to support use in Regulated Environments such as Food Service Equipment and Consumer Products. This Certification ensures reliable Performance in Applications where Safety and Regulatory Standards remain Critical Requirements.

Visual Performance remains an important aspect, as the Transparent Appearance allows use in Components requiring Visibility or Aesthetic Quality. At the same time, improved Stain Resistance and enhanced Toughness support durability in User-Facing Applications where Handling and Cleanliness are essential.

Processing Efficiency is supported through enhanced Flow Behavior, enabling consistent Mold Filling and easier production of detailed Parts. This Processing Stability allows Manufacturers to achieve uniform Part Quality while reducing Complexity in Molding Operations.

The Formulation provides Intermediate Hydrolytic Stability and good Chemical Resistance, allowing the Material to perform reliably in Environments exposed to Moisture, Cleaning Agents, and repeated Use. This ensures stable Performance across everyday Operating Conditions.

Available in Transparent Color Options, ULTEM™ DU319 PEI Blend Resin supports Applications where Optical Clarity, Aesthetic Appeal, and Functional Reliability must be delivered together.

ULTEM™ DU319 PEI Blend Resin enables Designers and Manufacturers to develop Food-Safe Components that balance Clarity, Durability, and Processing Efficiency. ULTEM™ DU319 PEI Blend Resin is also RoHS Compliant, supporting Environmentally Responsible Material Selection while delivering consistent Performance in Industrial and Consumer Applications.
