Regulatory & Compliance
- Biodegradability and Compostability
Beograde INJ033 fulfills the requirements of the existing standards for compostable and biodegradable polymers (EN 13432), because it can be degraded by microorganisms.
As the compostability of the end product is dependent on the geometry of product, it is the responsibility of the manufacturer of the end product to ensure compliance with the regulations.- Food Regulation
Beograde INJ033 complies in its composition with the European food stuff legislation for food contact, EU Directive 10/2011/EC (and the amendments 2018/213, 2018/831 and 2020/1245).
The material also complies with the US food contact notification for the main components: e.g. FCN 178, 475 and 907. A detailed food law status can be given on request. Whether the article is suitable for the application, has to be checked by the converter or packer.
Technical Details & Test Data
- Processing Conditions
Hopper 40 – 60 °C Feeding zone 165 – 175 °C Compression zone 170 – 180 °C Metering zone 180 – 190 °C Nozzle 190 – 200 °C Mold temperature 30 – 60 °C We recommend to use high injection speed. Short holding pressure and cooling times can be used.
General advice
Beograde is not compatible with a wide variety of other resins, and special purging sequences should be followed:
1. Before production, ensure to clean extruder and bring temperature to steady state with low viscosity, general purpose PP or PE.
2. Vacuum out hopper system to avoid contamination.
3. Introduce Beograde into the extruder at the operating conditions used in step one.
4. Once Beograde has purged, reduce barrel temperatures to desired set points.
5. At shutdown, purge machine with high viscosity polystyrene or polypropylene.- Product Carbon Footprint
- The product carbon footprint helps to define the amount of greenhouse gas emissions generated by a product along its life cycle, it quantifies the ghg-emissions related to the production of our products.
- Beologic calculates the carbon footprint of all sales products and this from cradle to gate.
- The calculation of the carbon footprint is in accordance with the internationally recognized Greenhouse Gas Protocol Product Standard which is based on the standard ISO-14067 norm and PAS2050.
- The carbon footprint is mentioned in our datasheet - by offsetting or compensating the calculated emissions we can present our products as Carbon Neutral compounds. This compensation is according the Verified Carbon Standard – more info via (www.v-c-s.org).
Storage & Handling
- Shelf Life
- 6.0
- Drying and Storage conditions
Beograde INJ033 is a compound of biodegradable polymers (such as PLA). Residual moisture content can lead to hydrolysis degradation. We recommend drying Beograde INJ033 at 70°C for a period of 2 – 4 hours. Don’t overheat or dry it longer than recommended.
Residual moisture content (> 0.2%) can result in lower melt stability, surface mark or bubble formation during processing.
We recommend to store the material in dry conditions below 50°C and protected from UV-light. Opened bigbag should be used immediately or adequately sealed back up after use to avoid moisture uptake and have negative effects on the physical properties of the product. It is recommended to use Beograde granules within a time period of maximum 6 months.
Finished product made from Beograde should be stored dry and cold. Storage time and lifetime of finished products depends on processing parameters and on storage conditions (moisture, UV radiation …).
