The eyewear sector is gradually adopting bioplastics for the manufacture of frames and accessories, in response to growing demand for sustainable, aesthetically pleasing products.
Alternatives to petroleum-based polymers in this field are mainly biobased polyamides such as PA11, or cellulose esters derived from plant fibers such as wood.
These thermoplastics are ideally suited to spectacle frames, notably for their mechanical properties, light weight and durability.
ADVANTAGES
- Compatible with existing processes
- Lightweight and durable
- Mostly biobased
- Potential improvement in environmental footprint
- Unique design incorporating by-products
The addition of by-products to these bioplastic matrices enables customized design with infinite possibilities for personalization (texture, color, finish, etc.).
In this way, they give a second life to a little-used product, for an innovative outlet.
