ULTEM™ 1000B Polyetherimide Film. Unique High Heat PEI Film

ULTEM™ 1000B Polyetherimide Film is a High-Performance Engineering Film developed for applications Operating under Extreme Thermal, Electrical and Safety Requirements. Manufactured from ULTEM™ 1000B Polyetherimide (PEI) Resin, this Advanced Film combines Exceptional Heat Resistance, Inherent Flame Retardancy, Outstanding Dielectric performance and Low Moisture Absorption, making it a preferred material for Electrical Insulation, Electronics, Aerospace and Industrial Systems where reliability is Critical.

Engineered specifically for demanding Environments, ULTEM™ 1000B Film offers Outstanding Thermal performance with a High Glass Transition Temperature (Tg) of 217°C. This allows the material to maintain its Mechanical Integrity, Dimensional Stability and Electrical properties under Prolonged exposure to Elevated Temperatures. for applications where Heat Management, Operational Safety and Long-Term performance are Essential, ULTEM™ 1000B Polyetherimide Film provides a Dependable Solution that significantly Outperforms Many Conventional Plastic Films.

The material features a Translucent appearance with a Polished Matte Surface, providing a unique balance of Aesthetics and Functionality. The Matte Finish Improves Handling and Processing while maintaining a Professional appearance suitable for Advanced Electronic and Industrial Assemblies.

A Significant benefit of ULTEM™ 1000B Film is its Naturally Low Moisture Absorption. Unlike Many Engineering Plastics that can Experience Dimensional Changes or Electrical Property Variations due to Humidity, ULTEM™ 1000B Polyetherimide Film retains excellent Dimensional Accuracy and consistent Dielectric performance even under Challenging Environmental Conditions. This Characteristic is especially valuable in Precision Electrical and Electronic applications.

Electrical Insulation performance is Another Key Strength of ULTEM™ 1000B. The material offers excellent Dielectric properties across a Broad Temperature Range, making it highly suitable for Electrical Barriers, Insulation Systems, Flexible Circuits, Transformers, Battery Assemblies and other High-Performance Electronic applications that require reliable Long-Term Electrical Performance.

For Safety-Critical applications, ULTEM™ 1000B Polyetherimide Film delivers Outstanding Flame Resistance. The material Achieves UL94 V-0 Classification at Thicknesses Ranging from 0.025 mm to 0.25 mm, providing Exceptional Fire performance without Relying on added Flame-Retardant Packages. This Inherent Flame Resistance makes the Film particularly attractive for Aerospace, Transportation, Electrical and Electronics applications where Stringent Fire Safety requirements must be Met.

Another important Advantage of ULTEM™ 1000B Film is its excellent Compatibility with Advanced Metallization and Lamination Processes. The material can be Sputter-Coated with Copper, Heat-Fused with Copper and Processed through Thermal Lamination Techniques, making it a Versatile Substrate for Flexible Electronics, Printed Circuits, Electrical Insulation Laminates and specialized Electronic Assemblies.

Available Thickness options include 0.025 mm, 0.038 mm, 0.050 mm, 0.075 mm, 0.100 mm, 0.125 mm and 0.175 mm. The 0.025 mm, 0.038 mm and 0.050 mm Grades are Supplied with a Matte/Matte Surface Finish, while Thicker Gauges are available for applications requiring greater Mechanical Strength and Insulation Performance.

ULTEM™ 1000B Polyetherimide Film is commonly Specified for Electrical Insulation Systems, Flexible Printed Circuits, Battery Insulation Components, Aerospace Electronics, Industrial Sensors, Transformers, Motor Insulation and other High-Temperature Electrical applications where Thermal Stability, Flame Resistance and Dielectric reliability are Essential.

The combination of High Heat Resistance, Low Moisture Absorption, excellent Electrical Insulation properties and Inherent Flame Retardancy makes ULTEM™ 1000B Polyetherimide Film One of the Most Capable Film Materials available for demanding Engineering Environments. In addition, the material is RoHS Compliant, supporting Environmentally Responsible Product Development and Global Regulatory Compliance.
