Properties of Polymers

Question 1

What are the 10 properties of polymers?

Answer 1

1. Heat capacity
2. Thermal expansion
3. Crystallinity
4. Permeability
5. Elastic modulus
6. Tensile strength
7. Resilience
8. Refractive index
9. Resistance to electric current (Insulator)
10. Unreactivity

Question 2

Extent to which the polymer acts as an effective insulator

Answer 2

Heat capacity

Question 3

Expands or contracts when heated or cooled

Answer 3

Thermal expansion

Question 4

Arranged in regular structure than random fashion

Answer 4

Crystallinity

Question 5

Tendency to pass extraneous materials (Low permeability - High barrier properties)

Answer 5

Permeability

Question 6

Substances resistance to being deformed elastically when stressed is applied

Answer 6

Elastic modulus

Question 7

Strength of plastic or force that must be applied in one direction

Answer 7

Tensile strength

Question 8

Ability to resist abrasion and wear

Answer 8

Resilience

Question 9

Extent to which the plastic affects light as it passes through polymers (Speed of light)

Answer 9

Refractive index

Question 10

Most polymers do not conduct electricity

Answer 10

Resistance to electric current (Insulator)

Question 11

It is not affected by air or water and chemicals (This makes plastics durable and protects many substances)

Answer 11

Unreactivity
