The corotating technology can also be applied for pipes production when one or more pipe layers are made of filled/reinforced materials, just like for the following reference applications:
> Extrusion of pipes for heating systems where the core layer is made of PP reinforced with glass fibres
> Extrusion of soil stacks/pipes where the core layer has a high percentages of mineral fillers for deadening purposes.
> Extrusion of generic purposes pipes using low cost materials filled with mineral fillers
