Barrier outperforms HDPE

Membrane specialist ITP claims to have developed a new hydrocarbon resistant barrier that outperforms current HDPE products.

According to ITP, while HDPE passes the current tests for chemical resistance, permeability tests show it is permeable to hydrocarbons and other environmental contaminants, because they are made from hydrocarbon based materials.

ITP says its new Puraflex product overcomes the problem because it is a chemical resistant multilayer barrier membrane incorporating both polar and non-polar polymers.

The installed cost is up to 20% more than HDPE, but ITP says this is heavily outweighed by substantially lower levels of risk.
