What is the unit for dielectric constant?
What is the unit for dielectric constant?
EXPLANATION: As dielectric constant is the ratio of two like quantities i.e. permittivity, it has no units and dimensions.
What is the dielectric constant of polypropylene?

What is the dielectric constant of polyethylene?
Dielectric Constants at 20°C
| Material | Dielectric Constant |
|---|---|
| Polyethylene | 2.25 |
| Polyvinyl chloride | 3.18 |

What is the symbol for dielectric constant?
κ
There is no standard symbol for the dielectric constant – you may see it referred to as κ, ε, ε′ or εr. In this TLP κ shall be used to avoid confusion with the absolute permittivity, which may also be given the symbol ε.
What is the electrical conductivity of polypropylene?
At low filler loading, the composites have a negligible conductivity corresponding to the usual value of pure polypropylene (10−14–10−16 S·m−1). At high filler concentrations, the materials exhibit a conductivity of about 10 S·m−1.
What is the dielectric constant of neoprene rubber?
6.7
