BAYER AG
Biodegradable polymer for injection moulding
As a follow-up to its well-known biodegradable "BAK 1095", Bayer AG (D-51368 Leverkusen) has developed a biodegradable polymer especially for injection moulding processes. Because of the new material's higher melting temperature (175°C/"BAK 1095": 125°C), it is conducive to even long or thin injection moulding applications. Its plasticity has also been significantly increased. A press release notes that this biodegradable petrochemical-based plastic is extremely versatile, as it can be modified by adding filler or reinforcement material. The rigidity of "BAK 2195" can be increased significantly by adding either mineral fillers or renewable resources such as hemp, cellulose, sawdust or starch. Possible applications include disposable plant pots, markers, baskets and ties as well as silverware. Bayer reports that these biodegradable polyester amides are comparable in stability and convertibility to the properties of conventional polyolefines. A study by the Franz-Patat-Zentrum (FPZ, Rebenring 33, D-38106 Braunschweig) on biodegradable polymers quotes the price of „BAK 1095" at DEM 7/kg for four-digit capacities.
