Examid® PPA GF50 Polyphthalamide Reinforced with 50 % Glass Fiber

Description

Examid® PPA GF50 is a highly filled engineering polyphthalamide specifically designed for operation under prolonged thermal and mechanical loads. Thanks to its 50 % glass fiber content, the material demonstrates extremely high stiffness, dimensional stability and creep resistance.

It retains its mechanical and electrical insulation properties even at elevated humidity, which is critical for applications in changing environments and under thermal cycling.

Examid® PPA GF50 is intended for high-precision parts with demanding requirements for geometric stability, flame retardancy and mechanical strength. A low coefficient of thermal expansion, heat resistance up to 285 °C (HDT/A) and a high tensile modulus make it an effective alternative to metal in functionally loaded assemblies, particularly in enclosed designs with tight fits.

Key advantages

• Ultra-high stiffness and strength
• High heat resistance: HDT/A up to 285 °C
• Retained impact strength at –30 °C
• Low coefficient of thermal expansion
• High dimensional stability
• Resistance to moisture and thermal aging
• Retains electrical insulation properties in humid environments
• Suitable for metal replacement in precision parts

Applications

• Precision guides and support assemblies in mechanisms operating under thermal loads (power tools, drive systems, measuring instruments)
• Automotive under-hood assemblies: mounting supports, protective covers, heat-insulating elements in cooling systems
• Transmission and drive components requiring maximum stiffness and resistance to vibration and thermal cycling
• Electrical products with dense packaging: housings, mounting plates, distribution blocks
• Power supply and inverter interfaces requiring creep resistance and precise positioning
• Industrial components as a metal alternative, in particular replacing aluminum or brass in contact with vapors, hot oils and pressure
• Sealing and structural elements in household or professional equipment with limited space and increased mechanical requirements
