Biodegradable masterbatches
Colouring is carried out almost exclusively with the help of colour masterbatches, which are made up of polymer carrier materials and corresponding colourants. For our AF-Eco® colour, carbon black and additive masterbatches, which we developed together with our sister company AF-COLOR, we only use biodegradable polymers as a carrier matrix. A wide range of colour and additive combinations are available.
They are ideal for use in injection moulding and for blown film, profile and sheet extrusion as well as for thermoforming applications. Thanks to our certified colour pool, we can meet almost any colour requirement.
All our masterbatches from the AF-Eco® product range are certified by TÜV AUSTRIA as OK compost INDUSTRIAL in accordance with EN 13432, based on the criteria defined below.
Some specific AF-Eco® masterbatch colour formulations are certified by TÜV AUSTRIA as OK compost HOME in accordance with NF T51-800 [11-2015], based on the criteria defined below.
Certification of degradability
No product is made to last forever. There are various end-of-life scenarios for products made from bioplastics. One of these is biodegradability in different environments, such as in an industrial composting plant, in domestic compost, in the soil or in water.
Independent test institutes measure the biodegradability and/or the biobased content on behalf of the customer and confirm this by awarding a test mark. This ensures market transparency and provides guidance for customers and consumers. In Europe, TÜV AUSTRIA (Belgium) and DIN CERTCO (Germany) are the most important certification institutes. In North America, it is the BPI institute.
Which criteria must be met?
Testing for certain limit values of heavy metals must first be successfully completed
The tests are carried out at approx. 60 °C:
1. Disintegration (end product): Min. 90 % must disintegrate within 12 weeks; remaining parts must not be larger than 2 mm
2. Biodegradation (powder): Min. 90 % within 6 months; measurement of CO2
Ecotoxicity test: Growth test with two plant species
Testing for certain limit values of heavy metals must first be successfully completed
The tests are carried out at approx. 28 °C
1. Disintegration (end product): Min. 90 % must disintegrate within 26 weeks; remaining parts must not be larger than 2 mm
2. Biodegradation (powder): Min. 90 % within 12 months; measurement of CO2
Ecotoxicity test: Growth test with two plant species
