ECOGEHR® PA 11 was developed as long ago as
1942. It is made 100% from the components of castor
oil, and is thus wholly bio-based. ECOGEHR® PA 11
possesses similar properties to PA 12, and an
excellent status with respect to applications that
require thermal, physical, chemical and mechanical
material properties. Good cold impact strength (down
to -40 °C), good chemical resistance and low water
absorption (only 1/6 in comparison with PA 6) are
characteristics of the material.

Examples of use:
* Castors
* Sliding, sealing and closing rings
* Toothed gears and sprockets

* wholly bio-based material
* good cold impact strength
* good chemical resistance
* low water absorption
