4. Features

Common features:

Operating temperature: -200 degrees to 260 degrees

Ease of processing: can be flanged, welded

Aging resistance: can be exposed to ozone and sunlight for a long time without aging

High transparency: The refractive index is the lowest among all plastics, and the flow of the medium in the pig can be viewed directly

Corrosion resistance: It can withstand all strong acids and strong oxidants except molten alkali metals, fluorinated media and those above 300°.

The role of strong reducing agent and various organic solvents

Unusual features:

Density: 2.14-2.17g/cm³

Volume resistance>1× 1018

Surface resistance>2× 1013
