Technical Data Sheet
Celion® is the world's first high quality and high purity cellulose acetate recovered from cigarette filters. The mechanical-chemical technology developed by IMEKO allows for the complete and purified recovery of the cellulose acetate present in cigarette butts, which is then used in the Celion® formulation.
Celion® pellets are formulated with 100% recovered cellulose acetate, resulting in a bioacetate that is completely free of phthalates and plasticized exclusively with biodegradable, plant-based additives.
In terms of processing and appearance, Celion® offers excellent versatility in colors and visual finishes with a strong level of transparency (featuring a subtle yellow tone and the potential presence of minor natural processing impurities). It is fully compatible with standard industrial processing techniques—including injection molding, extrusion, and compression—and offers a customizable formulation suited for high-end applications such as eyewear frames, jewelry, tools, and consumer goods. At the end of its life cycle, Celion® can be completely recycled by IMEKO.

Processing Parameters and Conditions
Typical values for processing by molding and injection:
| Parameters and conditions | Typical value |
|---|---|
| Injection temperature | 185 °C |
| Injection pressure | 140 bar |
| Injection Flow | 140 cm³/s |
| Tangential velocity | 140 m/min |
| Cooling time | 140 s |
| Pre-drying requirement (*) | 4-6 hours 70-90°C |

Processing parameters vary depending on the method and conditions employed.
Thermal Characterization and Toxicological Analysis
Results from Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) demonstrate the purity of the recovered cellulose acetate and its agreement with standard thermal profiles.
Chemical analyses rule out the harmful presence of heavy metals and organic compounds (PAHs), guaranteeing the chemical safety of Celion®.
