Polyéthylène (PE)

LD (Low Density) - HD (High Density)

Discrete impact strength.
Can be flexible (LD) or stiff (HD) depending on the formulation.
Mechanical properties depend on the crystallinity.
Good sliding properties.
Operation temperature from -40°C to +80°C depending on the type.
Low moisture absorption.
Resistant to (selection):
acids, alkaline solutions, alcohol, salt solutions, water, esters, oil, some types of petrol.
Not resistant to (selection):
strong oxidative agents, swelling caused by aliphatic hydrocarbons,
brittleness due to direct solar radiations.
