Polymers and their uses Flashcards
What are the properties and uses for the polymer poly(ethene)
Polythene
Properties = flexible, cheap, good insulator,
Uses = Plastic bags, plastic bottles, cling film, polytunnels
What are the properties and uses for the polymer poly(propene)
Polypropylene
Properties= Flexible, does not shatter
Uses = Buckets and bowls, crates, ropes, carpets
What are the properties and uses for the polymer poly(chloroethene)
Polyvinyl chloride, PVC
Properties = tough, good insulator, can be made hard or flexible
Uses = Window frames, gutters, pipes, insulation for electrical wires
What are the properties and uses for the polymer poly(tetrafluoroethene)
PTFE, Teflon
properties = tough and slippery
Uses = non stick coating for frying pans, burette taps, stain proof clothing
What is the problem with polymers
They are not biodegradable
Why shouldn’t plastics be incinerated
They produce CO2, which is toxic
How can we reduce landfill
Reduce uses,
Reuse products,
What is the process for recycling polymers
Collect waste. Sort waste into different polymers, Dispose stuff which can’t be recycled, Clean, grind into chippings, Purify, melt
Why are codes used on certain plastic products
Makes it easier to identify which polymers are in what products
How can PVC be made softer
You can include Plasticisers in its manufactory
