| JTYPEI® NA is a natural, unfilled PEI sheet developed for machined components requiring inherent flame resistance, low smoke generation, electrical insulation, dimensional stability and reliable performance at elevated temperatures. It is suitable for selected aircraft interior systems, aerospace electrical equipment, automotive electronics, electric vehicle battery systems, sensors, lighting systems and high-temperature insulating components. Sheets are available in thicknesses from 1 to 100 mm, with cut-to-size supply, controlled annealing and precision CNC machining available. Performance and regulatory compliance must be confirmed according to the selected resin grade, sheet thickness, finished component design and applicable industry standard. | |||||||||
JTYPEI® NA is a natural, unfilled polyetherimide sheet for machined aerospace and automotive components requiring a combination of inherent flame resistance, low smoke generation, electrical insulation, mechanical strength and long-term heat resistance.
The material is normally translucent amber and can be manufactured from SABIC ULTEM™ 1000 resin according to customer requirements.
Unlike conventional engineering plastics that may require additional flame-retardant additives, PEI offers inherent flame resistance in standard unfilled formulations. This makes it useful for electrical, electronic and interior transportation components where heat resistance, weight reduction and fire performance must be considered together.
JTYPEI® NA sheet is intended for machining flat, structural and insulating components. Suitability must be evaluated according to the final component geometry, material thickness, mechanical load, operating temperature, chemical exposure and applicable fire-safety standard.
ULTEM™ is a trademark of SABIC.
Natural PEI is inherently flame-resistant and can provide UL94 V-0 performance depending on the selected resin grade, material thickness and test conditions.
Its flame resistance is achieved without relying on conventional halogenated flame-retardant additives in many standard formulations.
The flame rating of the raw resin should not automatically be treated as certification of the extruded sheet or finished machined component.
PEI produces relatively low smoke when compared with many conventional thermoplastics.
This property is particularly valuable for enclosed transportation environments where smoke generation and visibility during a fire event are important design considerations.
Actual smoke-density and toxicity performance must be confirmed through the applicable material or finished-component test.
JTYPEI® NA can provide long-term service at temperatures up to approximately 170°C, depending on mechanical load, chemical exposure, pressure and component design.
Its glass transition temperature is approximately 217°C, enabling PEI to maintain useful strength, stiffness and dimensional stability at elevated temperatures.
The glass transition temperature must not be treated as the recommended continuous operating temperature of a finished part.
Natural unfilled PEI provides high volume resistivity, good dielectric strength and stable electrical performance across a wide temperature and frequency range.
It is suitable for components that combine mechanical support with electrical separation, including insulating plates, spacers, terminal supports, sensor components and battery-system insulation.
PEI combines low moisture absorption, good creep resistance and relatively low thermal expansion.
These properties help machined components maintain dimensional accuracy during assembly, thermal cycling and long-term operation.
Controlled annealing can be provided for parts requiring tight tolerances or extensive material removal.
PEI has a substantially lower density than metals and can help reduce component weight in suitable aerospace and automotive applications.
It may also eliminate secondary corrosion protection and electrical insulation treatments required by some metal components.
JTYPEI® NA PEI sheet can be evaluated for machining selected non-primary structural, electrical and interior aerospace components.
Potential applications include:
• Interior equipment brackets
• Electrical insulating panels

PEI is especially useful where low weight, flame resistance, electrical insulation and dimensional stability are required together.
PEI sheet can be machined into:
• Electrical insulating plates

JTYPEI® NA may also be used for:
• Aerospace assembly fixtures
• Electrical test fixtures
• High-temperature positioning tools
• Insulating supports
• Inspection-equipment components
• Precision alignment plates
Use of PEI in an aerospace application does not automatically mean that every PEI sheet or machined component complies with FAR/CS 25.853, OSU heat-release, smoke-density, toxicity or an aircraft OEM specification.
Required test reports and material documentation must be confirmed before the product is specified for a regulated aerospace application.
Natural PEI sheet can be machined into electrical insulating components used around:
• Battery modules
• Busbar systems
• Charging equipment
• Power-control units
• Electric motors
• High-voltage connectors
• Sensor assemblies
• Electrical distribution equipment
Its electrical insulation, flame resistance and dimensional stability make it useful for components exposed to elevated temperatures and electrical loads.
Required creepage distance, clearance, dielectric strength, voltage, temperature and environmental exposure must be evaluated in the final design.
Potential components include:
• Battery insulation plates
• Module spacers
• Terminal barriers
• Sensor supports
• Cable-routing components
• Battery equipment fixtures
• Thermal-management system supports
• Electrical separation components
PEI should not be represented as a thermal-runaway barrier or certified battery fire-protection material unless the finished construction has been tested according to the applicable standard.
PEI sheet can be machined into:
• Sensor mounting plates
• Electronic control-system supports
• Insulating housings and covers
• Connector components
• Relay and switch supports
• Precision positioning components
• High-temperature electrical fixtures
The dimensional stability and heat resistance of PEI make it suitable for selected lighting-system and optical-equipment components, including:
• Lamp-support components
• Reflector mounting parts
• Sensor and camera supports
• Insulating spacers
• Precision adjustment components
PEI may be considered for selected components exposed to elevated temperatures, automotive fluids and electrical requirements.
Chemical compatibility must be confirmed for the actual fluid, concentration, temperature, pressure, exposure time and mechanical stress.
