Possibility of a non-exhaustive selection of several other plastic polymers, either homogenous and/or reinforced with fibres, which can also serve the “UHCS” design.
The generic choice of privileging PET has been made because of its appropriate qualities, non-toxicity and availability all over the world.
This choice certainly does not rule out the occasional use of other polymers that are better suited to the prevailing climatic features, more readily available or because of opportunities provided by regional circumstances.
But UHCS does impose two rules:
- No mixing of polymers when the three “UHCS” profile sections are manufactured so as to guarantee the ease of subsequent recycling
