Modern Materials

constarch polymers :

* replace oil based thermoplastics
* made from crops
* dont have needed properties

paperfoam:

* alternative to thermoplastics
* made from starch based polymers and paper fibres
* scratch resistant inserts
* biodegradable, can be dyed and lightweight.

lyocell:

*high strength paper fibre
*environmentally freindly

Polymorph: this is a special plastic often used for modelling, it stays hard and white at room temperature but can be soften at 60'c. making it feel like plasticine, this gives the advantage that it can be moulded, it is ideal because it is a lot harder at room temperature, this means a massive level of accuracy can be achieved and if something needs to be changed it can be easily.  it is considered a 'smart material' because it returns to its original form when the…
