Polyamide with 30% glass fibres (PA 6 GF 30), Polyamide with 30% glass beads (PA 6 GB 30)
Polyamide (PA 6)
Polyamide 6 (PA 6) materials are semi-crystalline thermoplastics. Through water absorption (up to 3%), they become tough and have the following properties:
- High impact strength
- High abrasion resistance
- Good anti-friction properties
The strength and application temperature for highly stressed components can be increased enormously by adding 10 to 60% glass fibres (GF).
Adding glass beads (GB) increases the component rigidity and prevents deformations during cooling. Changes in dimensions as a result of water absorption must be taken into account when polyamide is used.
