Cellulose is a natural polymer that forms the structural backbone of the entire plant kingdom. By reacting cellulose with acetic anhydride, cellulose acetate is obtained; it is then compounded with plasticizers to improve its physical properties and processability.
Thanks to these characteristics, cellulose acetate has become one of the most important raw materials in the production of high-quality eyewear and components with strong aesthetic value.
It is for this very reason that
Mazzucchelli 1849 S.p.A. anticipated market evolution by developing in its M49 laboratories an innovative formulation that combines high physical-mechanical performance with environmental sustainability. In M49, the traditional plasticizer has been replaced with a plant-based plasticizer, making the material a bioplastic with a significant bio-based content.
What is a Bioplastic
According to the definition of the European Bioplastics Association, bioplastics include different families of materials with varying properties and can be divided into three main categories:
▶ Bio-based or partially bio-based
▶ Biodegradable, even if derived from fossil resources
▶ Bio-based and biodegradable
M49 is both bio-based and biodegradable. It is important to note that not all plastics of natural origin are biodegradable, and that in some cases plastics derived from fossil sources can be biodegradable as well.
The distinctive value of M49 lies precisely in its ability to meet both requirements, combining technical performance, aesthetics, and respect for the environment.
