GCSE D&T POLYMERS Flashcard

Front

What are the two main types of polymers?

Back

Natural polymers and synthetic polymers

Front

What are the key properties of polymers?

Back

Long chains of repeating units, flexibility, durability, and ability to be molded

Front

How can sustainability be achieved in polymer production?

Back

Using renewable raw materials, improving energy efficiency, reducing waste, and implementing recycling programs

Front

Example of an application of polymers in everyday life.

Plastic bags

Front

What is the difference between thermoplastics and thermosetting polymers?

Back

Thermoplastics can be melted and reformed multiple times, while thermosetting polymers cannot be remelted once they are formed.

Front

What is the significance of polymer recycling?

Back

It helps reduce waste in landfills, conserves natural resources, and reduces the environmental impact of plastic production.

Front

Biodegradable polymers

Back

Materials that can be broken down by microorganisms into natural substances

Front

What are the challenges in using polymers for packaging?

Back

Environmental impact, recycling challenges, and potential health concerns.

Front

How can the properties of polymers be modified to suit specific applications?

Back

By changing the monomer composition, molecular weight, and processing conditions.
