| JTYPEI® GF30 is a 30% short-glass-fiber-reinforced polyetherimide sheet developed for components requiring higher stiffness, lower thermal expansion and improved dimensional stability compared with natural unfilled PEI. Standard sheets are available in thicknesses from 5 to 100 mm, a standard width of 620 mm and lengths of 1,000 mm, 2,000 mm and 3,000 mm. SABIC ULTEM™ 2300 resin, cut-to-size plates, controlled annealing and precision CNC machining are available according to customer requirements. | |||||||||
JTYPEI® GF30 is a high-stiffness polyetherimide stock-shape sheet reinforced with 30% short glass fiber.
Compared with natural unfilled PEI, the glass-fiber reinforcement increases stiffness, reduces thermal expansion and improves resistance to deformation under mechanical load and repeated temperature changes.
JTYPEI® GF30 sheet is intended for CNC-machined plates, structural supports, equipment fixtures, electrical insulating components and precision parts requiring greater dimensional stability than natural PEI can provide.
SABIC ULTEM™ 2300 resin can be selected for customers requiring a recognized resin grade, resin traceability and supporting documentation.
ULTEM™ is a trademark of SABIC.

The 30% glass-fiber reinforcement significantly increases the stiffness of PEI.
JTYPEI® GF30 is suitable for structural plates, supports and fixtures that must resist bending or dimensional movement under mechanical load.
The allowable load for a finished component depends on operating temperature, load duration, part geometry, fiber orientation, fixing method and the required safety factor.
PEI GF30 provides lower thermal expansion than natural unfilled PEI.
This helps machined components maintain more stable dimensions during equipment start-up, heating, cooling and repeated thermal cycling.
Lower thermal expansion is particularly useful in assemblies containing metal inserts, sensors, fasteners or accurately positioned components.
The combination of glass-fiber reinforcement, low moisture absorption and good creep resistance helps components maintain stable dimensions.
For precision components requiring tight tolerances, rough machining, intermediate stress relief and final machining may be recommended.
JTYPEI® GF30 can provide reliable performance at elevated temperatures.
Long-term service temperature depends on mechanical load, chemical exposure, component thickness, fixing method, pressure and expected operating life.
The temperatures in the technical data table are material reference values and must not be treated as guaranteed operating limits for every finished component.
Standard PEI GF30 is generally an electrically insulating material.
It can be used for components that provide both structural support and electrical separation.
Electrical performance must be confirmed according to component thickness, operating voltage, frequency, moisture, temperature and the applicable electrical standard.
PEI is inherently flame-resistant in many standard formulations.
PEI GF30 may achieve UL94 V-0 performance depending on the selected resin grade, sheet thickness and test conditions.
Industry-specific flame, smoke and toxicity requirements must be verified according to the resin grade and final component.
JTYPEI® GF30 sheet can be machined into:
• Structural mounting plates
• Precision fixture plates
• Electrical insulating plates
• Equipment supports
• Sensor mounting plates
• Connector support components
• Semiconductor-equipment fixtures
• Automation-system components
• High-temperature equipment parts
• Positioning plates
• Test fixtures
• Lightweight structural brackets
• Thermal-cycling equipment components
• Custom CNC-machined parts
Final material suitability must be confirmed according to load, temperature, chemical exposure, voltage, vibration, fatigue and component geometry.
