Rotational moulding is actually a very suitable process for the manufacture of fuel tanks of all types - including those for marine applications. Both diesel and petrol tanks are commonly manufactured from either LLDPE (linear low-density polyethylene), or XLPE (cross-linked polyethylene), and for diesel applications no further processing is required.
In the case of petrol, post moulding fluorination is used to provide the barrier properties to meet permeation regulations. However, other materials may be used, either on their own or in conjunction with polyethylene (normally as an inner layer) to provide enhanced performance, such as improved heat resistance or barrier properties.
