PA11 (Nylon 11)
A nylon made from castor oil; more flexible and impact resistant than PA12.
What is PA11 (Nylon 11)?
PA11 is a bio-based nylon made from renewable castor oil. It offers higher elongation and impact strength than PA12, making it suitable for clips, hinges and parts that are repeatedly bent or take impacts.
- High strength
- Chemical resistant
- Flexible
