Cast polyamide 6 (PA6 G)
DIN Abbrev: PA6 G
Short description of Material:
PA6 G is produced by direct polymerisation in moulds and has a partially crystalline structure. The high crystallinity gives it excellent mechanical properties such as high abrasion, high wear resistance as well as good hardness and stiffness.
Applications
- Sheaves
- Castors
- Gears
- Bearings
- Guide strips
