PSU-GF
Glass-fiber reinforced PSU is a modified compound manufactured by incorporating short glass fibers into the base PSU resin. It is typically available in three standard grades containing 10%, 20%, and 30% glass fiber, respectively.
The addition of glass fibers significantly enhances the rigidity, tensile strength, and dimensional stability of the material, while fully retaining the inherent heat resistance, flame retardancy, and hydrolysis resistance of the base PSU. The resin is presented as opaque pellets in light amber or off-white color.
Technical Parameters
Item | PSU-GF10 | PSU-GF20 | PSU-GF30 |
Density (g/cm³) | 1.33 | 1.40 | 1.49 |
Tensile Strength (MPa) | 85 | 105 | 120 |
Elongation at Break (%) | 5-7 | 4-5 | 3-4 |
Flexural Strength (MPa) | 145 | 170 | 195 |
Flexural Modulus (GPa) | 4.0 | 5.8 | 8.0 |
Notched Izod (kJ/m²) | 6.5 | 6.0 | 5.5 |
HDT (°C, 1.82 MPa) | 178 | 182 | 186 |
Flammability (UL94, 0.75 mm) | V-0 | V-0 | V-0 |
Molding Shrinkage (%) | 0.3-0.4 | 0.25-0.35 | 0.20-0.30 |
Water Absorption (%, 24h) | 0.20 | 0.18 | 0.15 |
Continuous Service Temp.(°C) | -50 ~ +180 | -50 ~ +180 | -50 ~ +180 |
Features:
- High stiffness: 20% GF flexural modulus reaches 5.5-6.5 GPa, roughly double that of the natural grade
- High strength: tensile strength raised to 90-120 MPa at 20-30% GF
- Outstanding dimensional stability: low CLTE approaching metal levels; mold shrinkage reduced to 0.2-0.4%
- Excellent creep resistance: minimal deformation under long-term load - ideal for precision structural parts
- Heat resistance further improved: HDT up to 180-185°C (30% GF), suitable for high-temperature environments
- Intrinsic flame retardancy retained: UL94 V-0 achievable at ≥ 0.75 mm
- Hydrolysis and steam resistance: withstands repeated high-temperature steam sterilization
- Good processability: slightly lower flow than natural grade; mold design should account for fiber orientation
Typical Applications:
1）Automotive turbocharger housings, sensor enclosures, and fuel system components
2）Electronic connectors, coil bobbins, and relay housings
3）High-temperature structural components, chemical pump housings, and valves
4）Medical device handles and structural components
5）Aerospace high-temperature brackets
