Modified Glass-Filled Polyamide Examid PA6 GF20
Description
Heat-stabilized polyamide 6 with 20% glass fiber, black. Modifiers based on a new technology provide reduced moisture absorption, high strength and material savings thanks to the lower weight of finished parts.
Advantages
- reduced part weight compared with standard glass-filled PA6
- good stiffness combined with resilience and ductility.
- withstands complex loads very well
- higher heat resistance compared with PA6-L-SV30
- UV-stabilized
- resistant to thermal-oxidative aging
Applications
Industrial and household products requiring high strength. Industries: automotive, machine building, electrical engineering, furniture and hardware.
