But the essential principle is outwardly very straightforward to comprehend, even if it is highly complex to perfect.
It calls for just two ingredients: — the top end oilfield polymer PEEK (polyether ether ketone) that provides sealing, plus fibres of carbon to give strength. These two ingredients are combined in a roughly 50:50 proportion and this embedded fibre mix is then pre-manufactured into spools of thin, narrow tape — about a thumb’s width and not much thicker than an everyday binding tape.
