| JTYPEI® NA PEI rod is used for precision-machined mechanical components requiring dimensional stability, electrical insulation, inherent flame resistance and reliable performance at elevated temperatures. Typical components include bushings, rollers, sleeves, spacers, guides, insulating supports and equipment fixtures. Natural PEI and 30% glass-fiber-reinforced PEI GF30 options are available, together with cut-to-length supply, annealing and precision CNC machining. | |||||||||
JTYPEI® NA polyetherimide rod is suitable for precision mechanical components that require a combination of dimensional stability, mechanical strength, electrical insulation and long-term heat resistance.
The round stock shape is particularly efficient for CNC turning. It reduces material waste when producing cylindrical components such as bushings, rollers, sleeves, spacers, guides and insulating supports.
Natural PEI typically provides long-term service at temperatures up to approximately 170°C, depending on mechanical load, chemical exposure, pressure and other operating conditions. Its glass transition temperature is approximately 217°C.
These temperatures are typical material references and should not be treated as guaranteed operating limits for every finished component.
Natural PEI rod can be machined into bushings and sleeves used in electrical, electronic and industrial equipment.
Its electrical insulation, dimensional stability and low moisture absorption make it useful where a component must provide both mechanical positioning and electrical separation.
PEI should not automatically be selected for heavily loaded, high-speed or dry-running bearing applications without evaluating pressure, sliding speed, friction, wear and lubrication.
For demanding sliding or bearing applications, PEEK bearing grades or other wear-modified materials may be more suitable.
PEI rod can be machined into guide rollers, positioning rollers and handling components used in automation and precision equipment.
The material maintains good stiffness and dimensional stability at elevated temperatures. It is suitable for rollers that require electrical insulation, low weight and accurate geometry.
The actual operating load, rotational speed, contact pressure and counter-surface material should be evaluated before final material selection.
PEI is frequently selected for mechanical and electrical spacers because it combines:
• Electrical insulation
• Inherent flame resistance
• Low smoke generation
• Good dimensional stability
• High-temperature performance
• Low component weight
• Precision machinability
Typical applications include electrical equipment, sensor assemblies, test equipment, automation systems and high-temperature fixtures.
PEI rod can be converted into lightweight structural supports, mounting components and equipment brackets.
Natural PEI is suitable for components requiring balanced toughness, machinability and insulation.
For structural parts exposed to higher static loads or thermal cycling, PEI GF30 may provide better stiffness and lower thermal expansion.
JTYPEI® NA can be machined into guide components, locating pins, positioning blocks and alignment parts.
Low moisture absorption and good dimensional stability help finished components maintain consistent dimensions during assembly and operation.
For very tight tolerances, rough machining, intermediate annealing and final machining may be required.
PEI can be used for high-temperature jigs, assembly fixtures, positioning tools and insulating equipment components.
The material is especially useful where conventional engineering plastics cannot maintain sufficient stiffness or dimensional stability at the required temperature.
Natural PEI can provide long-term performance at temperatures up to approximately 170°C, depending on mechanical load and environmental conditions.
This makes it suitable for equipment components exposed to temperatures beyond the practical range of many conventional engineering plastics.
PEI combines low moisture absorption, good creep resistance and relatively low thermal expansion.
These properties help machined parts maintain dimensional accuracy during temperature changes and long-term mechanical loading.
Natural unfilled PEI provides high volume resistivity and good dielectric strength.
It is suitable for components that must perform both mechanical and electrical insulation functions.
PEI provides high tensile and flexural strength together with a favorable strength-to-weight ratio.
It can replace metal in selected applications where reduced weight, corrosion resistance and electrical insulation are required.
PEI is inherently flame-resistant in many standard formulations and can provide low smoke generation.
The applicable UL94 or industry-specific flame rating depends on the resin grade, product thickness and final component design.
