Waterproofing

Rotational moulding, in single or multiple layers, creates an effective barrier against liquids, gases, hydrogen and waves. It can also offer good resistance to permeation.

Rotational moulding copes with liquid permeation

According to a petrol evaporation test, rotomoulded tanks show no loss after 8 weeks at 40°C.

Rotational moulding copes with hydrogen permeation

Hydrogen is the smallest molecule on Earth. Hyperbaric hydrogen tanks exist to store these molecules within the tank.
