Polymers - Elastomer

Question 1

Natural Rubber (polyisoprene)

Answer 1

high tensile strength, electrical insulator, cold resistance. e.g. tires, balloons, hoses.

Question 2

Butadiene Rubber (BR)

Answer 2

tough, friction resistant, electrical insulator. e.g. shoe soles, conveyor belts.

Question 3

Neoprene (polychloroprene rubber)

Answer 3

thermal resistance, chemical and oil resistance, weather resistance, abrasion resistance, electrical insulator. e.g. wetsuits, wire insulation.

Question 4

Silicone

Answer 4

flexible, extremely temperature resistant, lubricant qualities, electrical insulator. e.g. cooking utensils, flexible ice cube trays.
