Modification of properties (AQA GCSE Design and Technology): Flashcards

Special ingredients to enhance/change polymer properties

Prevent discoloration/brittleness from sunlight exposure

Reduce damage from microorganisms (bacteria & fungi)

Prevent decomposition at high temps during manufacturing

Create strong, rigid structures when mixed with resin

Reduce costs while maintaining functionality

Make rigid polymers more flexible & improve flow in molding

Change the colour of polymers from natural base colour

Mask unpleasant smells from the base polymer

Plant-based materials

Moisture & warmth via bacterial action

3D printing filaments, disposable cutlery, compost bags

Moulded/remoulded at low temps by hand

Low chemical resistance
