JUTAIPPS® GF40 Glass-Fiber-Reinforced PPS Sheet
Availability:
Quantity:
JUTAIPPS® GF40 is a 40% glass-fiber-reinforced PPS sheet developed for high-stress structural components requiring high stiffness, low thermal expansion, creep resistance and dimensional stability at elevated temperatures.
The material is suitable for precision support plates, electrical structures, equipment housings, thermal-management components, semiconductor fixtures and industrial structural parts.
Cut-to-size supply, controlled annealing and precision CNC machining are available according to customer drawings and application requirements.
PPS GF40 Sheet is a 40% short-cut glass fiber reinforced PPS grade that offers higher stiffness and creep resistance compared to other PPS grades. Due to its improved dimensional stability, this grade performs excellently in structural applications involving high static loads, even over long periods and at high temperatures. Although the glass fiber reinforcement enhances the material's dimensional stability, this additive can cause wear on mating surfaces in sliding parts.

High-Stiffness PPS GF40 Sheet for Structural Components
JUTAIPPS® GF40 is a black, 40% glass-fiber-reinforced polyphenylene sulfide sheet designed for structural applications involving elevated temperatures, static mechanical loads and repeated thermal cycling.
Compared with unfilled PPS, PPS GF40 provides higher tensile modulus, higher flexural modulus, lower thermal expansion and improved resistance to creep and deformation.
These properties make it suitable for structural plates, equipment supports, high-temperature housings, electrical fixtures and precision components that must maintain geometry under mechanical and thermal stress.
Cut-to-size supply and precision CNC machining can be provided according to customer drawings.
Key Properties of PPS GF40 Sheet
High Structural Stiffness
JUTAIPPS® GF40 provides a tensile modulus of at least 5.0 GPa and a flexural modulus of at least 7.0 GPa.
The higher modulus helps structural plates and supports resist bending and deformation under load.
Low Thermal Expansion
The coefficient of linear thermal expansion is ≤45 × 10⁻⁶/K under the referenced test conditions.
This helps machined components maintain dimensional alignment during temperature changes and repeated thermal cycles.
High Heat-Deflection Temperature
JUTAIPPS® GF40 provides a heat-deflection temperature of at least 230°C at 1.80 MPa.
This makes it suitable for structural components exposed to a combination of heat and mechanical stress.
Heat-deflection temperature should not be treated as the guaranteed continuous operating temperature of every finished component.
Creep Resistance
Glass-fiber reinforcement improves resistance to long-term deformation under static load.
This is valuable for mounting plates, support structures, equipment frames and other components that must maintain dimensions over long service periods.
Chemical Resistance
The PPS matrix offers excellent resistance to many acids, alkalis, oils, fuels, coolants, hydrocarbons and industrial chemicals.
Chemical compatibility must be evaluated according to the actual medium, concentration, temperature, pressure and exposure time.
Low Moisture Absorption
Water absorption is ≤0.05% under the referenced test conditions.
Low moisture absorption helps PPS GF40 components maintain dimensional stability and electrical properties in humid or wet environments.
Electrical Performance
JUTAIPPS® GF40 provides high volume resistivity and good dielectric strength.
It can be used for structural electrical components where stiffness, dimensional stability and insulation are required.
Inherent Flame Resistance
The material can achieve UL94 V-0 performance at the specified test thickness.
The applicable rating of a finished part depends on the resin grade, thickness and final component design.
Semiconductor suitability must be verified according to cleanliness, outgassing, ionic contamination and chemical-exposure requirements.
Automotive and New Energy
JUTAIPPS® GF40 can be considered for:
• Battery-system supports • Electrical insulation structures • Sensor housings • Motor support components • Charging-system parts • Thermal-management structures • High-temperature electrical brackets • Lightweight structural components
Chemical and Industrial Equipment
Typical uses include:
• Pump support plates • Valve support structures • Chemical-resistant machine components • Process-equipment plates • Fluid-handling support components • Metering-system structures • Corrosion-resistant fixtures
Machining Considerations
Glass-fiber-reinforced PPS is more abrasive than natural PPS.
For machining PPS GF40 sheet:
• Use carbide or diamond-coated cutting tools • Provide stable support across the sheet • Avoid excessive clamping pressure • Control cutting heat • Use effective dust extraction • Inspect cutting tools regularly • Use staged machining for tight tolerances • Consider annealing for extensive material removal
Machining can expose glass fibers and produce a less uniform surface than natural PPS.
PPS GF40 should not automatically be used as a sliding surface against soft metals or plastics because the exposed glass fibers may increase mating-surface wear.
