TREEPLAST®
is a fully biodegradable raw material suitable for processing in standard
injection molding.
The final product can be finished like wood and has comparable possibilities
like MDF. The material is suitable for all kinds of wood connections.
For a sound design of products in TREEPLAST one has to take into account
the specific properties. For temporarily products the humidity is of
importance. For more durable products the TREEPLAST has to be in a dry
surrounding or finished (lacquer) to withstand humidity. Products of
TREEPLAST are skin friendly and not electrostatic. The freedom of shape
is a huge advantage above normal wood products. The material is shrink-free.

Qualities |
|
When designing
products in a material, it's important to utilize the specific qualities
of the material. In the case of the basic version of TREEPLAST pay
attention to the following specific qualities:
- a high material
density
- natural appearance
- skin friendly
- well paintable
- the brittleness
This list of course
isn't complete but it's a good starting point for making a product design
in TREEPLAST. The TREEPLAST consortium can assist in product design
and production. For more info, click on "TREEPLAST-design".
