Elastomers Flashcards
1
Q
elastomers
A
polymers that do not need to be heated to deform and then return to original shape
2
Q
natural rubber polyisoprene
A
high tensile strength, low elongation, good hardness compared to other elastomers, tough, electrical insulator, good cold resistance
3
Q
butadiene rubber BR
A
tough, excellent wear resistance against friction, good thermal resistance against friction, electrical insulator
4
Q
neoprene polychloroprene rubber
A
good thermal resistance, toughness, good oil and chemical resistance, excellent weather resistance, good abrasion resistance and electrical insulator
5
Q
silicone
A
good flexibility at low temperatures, poor abrasion resistance to temperature extremes, good weather resistance, good lubricating qualities, electrical insulator
