OVERVIEW of ECOGEHR® PLA |
ECOGEHR® PLA
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.
PLA-N is used in applications in which biodegradability
is of particular interest. The material is
also translucent in thin-wall applications (a few
millimetres).
Examples: �� Sinking aids for fence posts
�� Tree guards in forestry
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.
PLA-L This white bio-polymer is approved for use with
both foodstuffs and toys.
Examples: �� Mouthpieces for woodwind
instruments
�� Knobs and buttons
�� Industrial brushes
�� The foodstuffs processing industry
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.
PLA-V is a relatively soft material and conforms to
European foodstuffs approval requirements.
Example: �� Writing implements
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.
Thanks to its wood fibre filling, PLA-WF has a woodlike
character and can be worked accordingly. This also
conforms to the toys standard EN 71-3.
Example: �� Wooden toys
