1Synthetic polymers are usually made from crude oil and are normally referred to as what?
plastics
2Plastics which do not soften with heat, tending only to char or burn, this type of material cannot be recycled.
Thermosetting polymer
3A thermoplastic often used for vacuum forming
HIPS - high impact polystyrene
4A thermoforming polymer often used for shop signs, baths, car lights and menu holders
Acrylic (PMMA) Polymethylmethacrylate
5A thermosetting polymer that can degrade in soil and be disposed of in landfill sites
Biopol - used for disposable cups, razors and plastic cutlery
6A 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
7A thermosetting polymer which is heat resistant and used for electreical fittings - plugs, sockets and swithches
Urea formaldehyde
8Most polymers are excellent insulators of heat and electricity. A mains cable is likely to be covered with which polymer?
PVC (polyvinyl chloride)
9Polymers 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
10The category of plastics which once heated and cooled sets hard and cannot be reformed or recycled
Thermosetting plasics = (Thermosetting polymers)
11The category of plastics which once heated and cooled can be heated and reformed again to make another recycled product
Thermoforming plastics = (Thermoforming polymers)
