| JUTAIPPS® GF40 is a 40% glass-fiber-reinforced PPS rod developed for electrical connectors, IC sockets, insulating supports and structural components requiring high stiffness, low thermal expansion and dimensional stability at elevated temperatures. Standard diameters range from Ø8 to Ø100 mm, with lengths of 1,000 mm, 2,000 mm and 3,000 mm. Cut-to-length supply and precision CNC machining are available according to customer drawings and application requirements. | |||||||||
JUTAIPPS® GF40 is a 40% glass-fiber-reinforced polyphenylene sulfide rod designed for components requiring higher stiffness, lower thermal expansion and better resistance to deformation than unfilled PPS.
The material is particularly suitable for electrical connectors, IC sockets, sensor supports, coil components, insulating structures and high-temperature mechanical parts.
Compared with natural PPS, the glass-fiber reinforcement substantially increases tensile modulus and flexural modulus while reducing dimensional movement during mechanical loading and thermal cycling.
Standard rods are available in diameters from Ø8 to Ø100 mm and lengths of 1,000 mm, 2,000 mm and 3,000 mm.
JUTAIPPS® GF40 provides a tensile modulus of at least 5.0 GPa and a flexural modulus of at least 7.0 GPa.
The higher stiffness helps thin or precision components maintain their geometry during assembly and operation.
The coefficient of linear thermal expansion is ≤45 × 10⁻⁶/K under the applicable test conditions.
Lower thermal expansion helps connector bodies, test sockets and insulating structures maintain dimensional alignment during repeated temperature changes.
JUTAIPPS® GF40 provides a heat-deflection temperature of at least 230°C at 1.80 MPa under the referenced test conditions.
This makes the material suitable for structural components exposed to elevated temperatures and mechanical load.
The material provides high volume resistivity and good dielectric strength.
Typical electrical applications include:
• Connector bodies
• IC socket components
• Insulating supports
• Coil frames
• Terminal components
• Sensor supports
• Electrical spacers
• Switch components
JUTAIPPS® GF40 can achieve UL94 V-0 performance at the specified test thickness.
The final component rating depends on product thickness, resin formulation and applicable testing requirements.
PPS provides excellent resistance to many industrial chemicals, oils, fuels, coolants and cleaning media.
Chemical compatibility must be confirmed under actual operating conditions.
