Cards in this deck (6)
- 1Describe Nylon-tough
-lightweight
-keeps water out
-keeps UV light out
-does not let water vapour through - 2What does a nylon jacket do?Sweat condenses which makes the wearer wet and cold inside their jacket
- 3Describe GOR-TEXHas all the properties of nylon but is:
-breathable - 4What does a GOR-TEX jacket do?Water vapour from sweat can pass through the membrane but rainwater cannot. (Worn by mainly active outdoor people)
- 5What new types of polymers are scientists developing-polymers that dissolve
-biodegradable polymers - 6What environmental and economical issues does existing polymers have?-Disposal of non-biodegradable polymers means land sites get filled quickly
-landfill means wasting land that could be valuable for other purposes
-Disposal by burning waste plastics makes toxic gases
-disposal by burning or using landfill wastes the crude oil used to make the polymers
-It's difficult to sort out different polymers so recycling is difficult
