Polymers - Thermoplastics

Question 1

Low Density Polyethylene (LDPE)

Answer 1

Weatherproof, low level of rigidity, very tough. e.g. carrier bags, food wrap.

Question 2

High Density Polyethylene (HDPE)

Answer 2

Weatherproof, tough, chemical resistant. e.g. long life bags, buckets.

Question 3

Polypropylene (PP)

Answer 3

Good fatigue resistance, tough, chemical resistance. e.g. container lids, food containers.

Question 4

High Impact Polystyrene (HIPS)

Answer 4

Hard, rigid, tough. e.g. yogurt pots, single use plastic cups. Can be vacuum formed.

Question 5

Acrylonitrile Butadiene Styrene (ABS)

Answer 5

Extremely tough, hard. e.g. domestic appliances casings.

Question 6

Polymethylmethacrylate (PMMA) / Acrylic

Answer 6

Tough, hard, available in many colors. e.g. baths, lighting units. Can be laser cut.

Question 7

Nylon

Answer 7

Tough, corrosion resistant, temperature resistant, friction resistant. e.g. cable ties, bearings.

Question 8

Rigid Polyvinyl Chloride (uPVC)

Answer 8

Rigid, tough, hard, weather resistant, temperature resistant, fire retardant. e.g. window frames, guttering.

Question 9

Flexible Polyvinyl Chloride (PVC)

Answer 9

Tough, flexible, weather resistant, chemical resistant. e.g. cable insulation, hose pipes.
