Polyethylene pipe material contains well dispersed fine particle size carbon black, choice polymer and stabilisers ensuring excellent weather resistance including UV radiation and long term stability and lifetime expectancy of more than 50 years.
Polyethylene material shows excellent resistance to rapid crack propagation and slow crack growth both being benefits for pressure pipes. PE100 & PE80 pipes are flexible and offer greater mechanical resistance when compared to other pipes.
The most important property of PE pipes is it's resistance to hydrostatic pressure. It defines the life expectancy of a pipe under internal pressure. The stress resulting in a fracture in PE plastic pipes depends on the test time and temperature.
