1
Synthetic polymers are usually made from crude oil and are normally referred to as what?
plastics
2
Plastics which do not soften with heat, tending only to char or burn, this type of material cannot be recycled.
Thermosetting polymer
3
A thermoplastic often used for vacuum forming
HIPS - high impact polystyrene
4
A thermoforming polymer often used for shop signs, baths, car lights and menu holders
Acrylic (PMMA) Polymethylmethacrylate
5
A thermosetting polymer that can degrade in soil and be disposed of in landfill sites
Biopol - used for disposable cups, razors and plastic cutlery
6
A thermosetting polymer that comes in a thick liquid form and can be used with glass fibres to make a composite material called GRP (glass reinforced plastic) to form boat hulls, sports car bodies
Polyester resin
7
A thermosetting polymer which is heat resistant and used for electreical fittings - plugs, sockets and swithches
Urea formaldehyde
8
Most polymers are excellent insulators of heat and electricity. A mains cable is likely to be covered with which polymer?
PVC (polyvinyl chloride)
9
Polymers can withstand rough handling making them suitable for a wide range of products in the home, industry and agriculture. for instance, wheelie bins, buckets and car bumpers. What is the term used to describe this quality?
toughness
10
The category of plastics which once heated and cooled sets hard and cannot be reformed or recycled
Thermosetting plasics = (Thermosetting polymers)
11
The category of plastics which once heated and cooled can be heated and reformed again to make another recycled product
Thermoforming plastics = (Thermoforming polymers)
