Regulatory & Compliance
- Biodegradability and compostability
Beograde 20 INJ044 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 20 INJ044 complies in its composition with the European food stuff legislation for food contact, EU Directive 10/2011/EC (and the amendments 2018/213 and 2018/831).
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
- Other information
We recommend to use high injection speed. Short holding pressure and cooling times can be used.
This Beograde contain wood fiber, please note that the temperatures must be kept low to prevent degradation of the wood which starts at approximately at 210°C.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.- Stability and Reactivity
Reactivity
The product is non-reactive under normal conditions of use, storage and transport.Chemical stability
Stable under normal conditions of use.Possibility of hazardous reactions
None under normal use.Hazardous decomposition products
Under normal conditions of storage and use, hazardous decomposition products should not be produced.
Storage & Handling
- Shelf Life
- 6.0
- Drying conditions and storage
Beograde 20 INJ044 is a compound of biodegradable polymers (such as PLA). Residual moisture content can lead to hydrolysis degradation. We
recommend drying Beograde 20 INJ044 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 …).
