The actual fibres are manufactured at a very limited number of industrial sites and are in general directly transformed within the same manufacturing process into articles that are subsequently used in a broad range of industrial equipment for high-temperature insulation, which can potentially lead to significant worker exposure.

For example, rare earths are essential for high performance permanent magnets in wind turbines or electric vehicles, catalytic converters for cars, printed circuit boards, optical fibres, and high temperature superconductors.

Moreover, the substrate for DOC is a single block honeycomb cylinder whereas the DPF substrate is formed by gluing several filtering elements and the channels of the DPF are plugged, which is not the case for DOC. It follows then that the production of the DPF substrate necessitates a non oxide high temperature sintering furnace, gluing system and plugging machines and these equipments are not necessary for the production of the DOC substrate. It appears therefore that it is not possible to produce DPF and DOC substrate on the same production lines without significant additional costs.

As far as the price is concerned, the Commission supports the view of Saint-Gobain and the interested party with withheld identity in this regard and observes that there is a big price difference between substrates of DOC and DPF, since the materials used for the substrates for DPF are higher performance materials whose production implies higher costs (for example, the use of a non-oxide high temperature sintering furnace is required).
