PEEK-GF Granules
Product Introduction:
PEEK glass fiber reinforced granules are modified with 10%~40% short-cut E-glass fibers in a PEEK matrix. The addition of glass fiber dramatically increases stiffness, strength, and dimensional stability, while elevating the heat deflection temperature to over 315°C, while retaining PEEK's inherent chemical and thermal resistance. Pellets appear dark amber to dark gray with slightly reduced surface gloss. A core material for metal replacement applications requiring high rigidity and dimensional precision.
Technical Parameters:
Parameter | TEST Standard | PEEK-GF10 | PEEK-GF20 | PEEK-GF30 | PEEK-GF40 | Unit |
GF Content | — | 10% | 20% | 30% | 40% | % |
Density | ISO 1183 | 1.38 | 1.44 | 1.51 | 1.58 | g/cm³ |

Flammability | UL94 | V-0 | V-0 | V-0 | V-0 | — |
Performance Features:
1)Tensile strength up to 230 MPa — over 150% increase vs. pure resin
2)HDT (1.8MPa) exceeds 315°C; suitable for high-temp load-bearing environments
3)Low anisotropic warpage; excellent dimensional stability (CLTE reduced ~50%)
4)Lower cost than CF-reinforced grades; excellent cost-performance ratio
5)Retains good chemical resistance and hydrolysis resistance
6)Density increases to 1.45~1.60 g/cm³ with higher GF content
Application:
1)Automotive: Transmission parts, pump housings, sensor housings, brake system components
2)Aerospace: Secondary structural parts, interior frames, radome components
3)Electronics/Electrical: High-temp connectors, bobbins, SMT reflow carriers
4)Industrial Equipment: Compressor valve plates, gears, bearing cages, chemical pump impellers
5)Oil & Gas: Corrosion-resistant downhole tool parts, insulated connectors
