Sources and stock forms of polymers

Design and technology

In this unit pupils will develop technical principles knowledge with an explicit focus on exam technique.

Put the stages in the correct order from source to stock form:

They are always made from recycled materials.

They're easier to transport, store and use in different manufacturing processes.

They don't require specialised tools to work with.

What is one main benefit of using standard stock forms in manufacturing?

What is the main source for synthetic, non-biodegradable polymers?

Put the following stages of processing polymers into order:

Match each stock form with the correct description:

Materials are chosen based on their physical and working {{}}.

it can maintain its shape under normal conditions without breaking

it can resist environmental changes like temperature and moisture

the cost-effectiveness of building a structure

What does 'structural integrity' refer to in materials and structures?

Which of these materials comes from a plant source?

Which group includes only natural materials?

Match the material category to its example:
