| About |
|---|
| High Temperature polyamide injection molding grade, 50% glass fiber reinforced. Highly improved thermal resistance in contact with hot air. Black colour. Suitable for applications in very severe temperature conditions, where the parts must endure long term contact with hot air until 220-230°C. Very good properties retention after ageing. Typical applications in automotive are under bonnet components, like turbo air ducts, intercooler end caps.&& |
