PLASTICS = polymers
- Materials that can acquire and maintain a certain
shape after being in a mould or deformed
- Molecule created by the join and repetition of
structural units called monomers ->polymerisation
- TYPES OF PLASTICS
- According to their internal structure
- Elastomers
- Elastic thermosetting
polymers
- Elastic thermosetting
polymers
- Thermosetting polymers
- 3-D chins of
polymers
- Can be moulded
applying heat and
pressure
- Difficult
to recycle
- 3-D chins of
polymers
- Thermoplastics
- Easy to break by applying heat and
come back together when they are
cooled -> easy to recycled
- Lineal
chain of
polymers
