Bioplastics: Renewable Raw Materials

Polylactide and polylactic acid (PLA) is a linear, aliphatic polyester. PLA is obtained from sugar or starch via fermentation by micro-organisms. This means that it is a thermoplastic polymer based on renewable raw materials. PLA materials are CO2-neutral due to the proportion of renewable raw materials.


*ECOGEHR® PLA-N* is a native PLA. It possesses good mechanical properties similar to the polystyrenes, high rigidity, a tensile module of elasticity of up to 3440 MPa, good resistance to polar solvents, is non-toxic and provides good thermal insulation.

*ECOGEHR® PLA-L* is a blend of polylactide, some lignin, natural fatty acids and waxes. It combines good mechanical properties comparable with ABS, high rigidity, a tensile module of elasticity of up to 2770 MPa, good impact strength down to -30°C, good resistance to polar solvents, good thermal insulation and is approved for use with foodstuffs and toys.

*ECOGEHR® PLA-V* combines the properties of PLA and a petroleum-based polyester. It possesses high strength, good thermal insulation, is non-toxic, and can be bonded and welded.

*ECOGEHR® PLA-WF* is a composite material of polylactide, a small amount of a petroleum-based polyester and wood fibres (30%). It possesses high mechanical strength thanks to the excellent binding of the wood fibres and the polymer blend. This is comparable with standard fibre-reinforced polymers. It also displays good thermal insulation and conforms to the standards governing toys.
