| JTYPEI® GF30 sheet is used for rigid fixture plates, structural supports, mounting plates and electrical insulating components that must resist deformation under mechanical load and repeated temperature changes. The 30% glass-fiber reinforcement provides higher stiffness and lower thermal expansion than natural PEI. JUTAI supplies cut plates and precision CNC-machined components according to customer drawings. For complete material properties and standard sheet sizes, refer to the JTYPEI® GF30 ULTEM™ 2300 PEI Sheet core product page. | |||||||||
High-load components do not fail because of material strength alone.
Long-term deformation, thermal expansion, fastener stress, stress concentration, component geometry and repeated temperature changes can also affect dimensional accuracy and service life.
JTYPEI® GF30 sheet is intended for flat or plate-shaped components requiring higher stiffness and better dimensional stability than natural unfilled PEI.
Typical parts include precision fixture plates, equipment supports, insulating mounting plates, sensor carriers, test jigs and structural components machined from sheet.
For this application, high load may include:
• Sustained static load
• Repeated mechanical loading
• Bending of unsupported plate sections
• Clamping force from bolts or fixtures
• Thermal expansion mismatch with metal components
• Repeated heating and cooling
• Vibration from industrial equipment
• Combined mechanical and electrical-insulation requirements
“High-load resistance” should not be interpreted as a universal load rating.
The actual allowable load must be determined according to component dimensions, support distance, operating temperature, load duration, fixing method, fiber orientation and the required safety factor.
The glass-fiber reinforcement increases stiffness and helps flat components resist bending under mechanical load.
This is useful for mounting plates, inspection fixtures, sensor bases and equipment supports that must maintain alignment.
PEI GF30 provides lower thermal expansion than natural PEI.
This can reduce dimensional movement when equipment repeatedly heats and cools or when plastic components are assembled with metal parts.
Fixture plates often contain locating holes, pockets, mounting surfaces and reference features.
The combination of higher stiffness, low moisture absorption and reduced thermal expansion helps maintain the relative position of these features.
Standard PEI GF30 is generally electrically insulating.
It can therefore be used for components that must provide mechanical support while electrically separating sensors, terminals, connectors or equipment assemblies.
Electrical suitability must be evaluated according to voltage, frequency, component thickness, creepage distance, clearance, temperature and moisture.
PEI GF30 can replace aluminum or other metals in selected components where reduced weight, corrosion resistance and electrical insulation are required.
Metal replacement must be supported by appropriate load, deflection, temperature and fastening calculations.
JTYPEI® GF30 sheet is particularly suitable for machining:
• Flat structural supports
• Mounting plates
• Precision fixture bases
• Inspection nests
• Sensor mounting plates
• Electrical insulating plates
• Terminal support plates
• Test-equipment fixtures
• Positioning jigs
• Lightweight equipment panels
• Thermal-cycling fixtures
• Semiconductor-equipment support plates
• Automation-system mounting components
• Components containing multiple drilled or milled features
Round bushings, sleeves, rings and cylindrical spacers should normally be produced from PEI GF30 rod rather than large sheets to reduce machining time and material waste.
