Polyamide 66 /Glass filled/ – PA66 GF30
DIN abbreviation: PA 66 GF30
Short description of material
This extruded polyamide has good hardness, stiffness and wear resistance but worse impact resistance. The properties of PA 66 are comparable to PA 6 G, however PA 66 absorbs more moisture and is less dimensionally stable.
Application examples:
- Component parts with a higher demand for dimensional stability and /or higher loads.
Colours: Black
