Semi-Aromatic PPA/PA66 Blend, 50% Glass Fiber — Examid® PPA PA66 GF50 Y

Description

Examid® PPA/PA66 GF50 Y is a heat-stabilized semi-aromatic blend (PPA + PA66) with 50% glass fiber. The line's flagship overall: flexural strength of 380 MPa, tensile modulus of 18,000 MPa, HDT of 285 °C at 1.8 MPa, melting at 325 °C.

Flow shrinkage of 0.1% is precision-level. The electrical package is complete: CTI of 600 V, dielectric strength of 30 kV/mm, volume resistivity of 10¹¹ Ω·m — the material qualifies for power electronics and high-voltage connectors, including e-mobility.

Cold performance: Izod unnotched 80 kJ/m² at −30 °C. Part service range — from −30 to +200 °C with retained stiffness. Processing: melt 325–340 °C, mold 140 °C. The position covers Ultramid® Advanced / Grivory HT GF50-class applications at a substantial price advantage.

Flagship PPA/PA66 GF50: HDT 285 °C, CTI 600 V, 0.1% shrinkage

Applications: power electronics and high-voltage connectors (including e-mobility), engine-zone parts, precision structural elements serving from −30 to +200 °C.
