Q
What are the properties of thermoforming plastics?
A
They dont resist heat well so are bendy and are easily recyclable
2
Q
What are the properties of thermosetting plastics?
A
They resist heat well so are harrd, rigid and arent easily recycled

A
Acrylic - hard, stiff, shiny and resists weather (e.g. bike visor, outdoor signs)
4
Q
What is an example of a thermosetting plastic?
A
Epoxy Resin - rigid, durable and a good electrical insulator (e.g. used in circuit boards)
5
