50% Glass Fiber PA66, Heat-Stabilized — Examid® PA66 GF50 Y

Description

Examid® PA66 GF50 Y is a heat-stabilized polyamide 66 with 50% glass fiber. The top rung of the PA66 GF line: tensile strength of 240 MPa, flexural modulus of 16,800 MPa, HDT of 250 °C at 1.80 MPa. A metal-replacement candidate after part-level validation.

Cold performance is proven at −30 °C: Charpy unnotched 90 kJ/m², notched 13 kJ/m² — the material does not embrittle in the cold, important for outdoor and automotive applications. Heat stabilization (Y) provides endurance in long-term hot-zone service.

Direct analog — Ultramid® A3WG10: a comparable profile with better economics. Processing: melt 285–300 °C, mold 80–120 °C, pressure 90–130 MPa.

Highly filled PA66 GF50 with −30 °C cold resistance for metal replacement

Applications: metal replacement, structural brackets and housings, under-hood parts, outdoor assemblies operating at −30…+150 °C, long-term loaded elements.
