FAQ
Frequently Asked Questions
How many products does PRT publish?
Ten substrate and catalyst products across six categories, all listed on this page.
What is the difference between a substrate and a catalyst?
A substrate is the bare honeycomb carrier in ceramic or metal. A catalyst is that carrier after coating with the active formulation, for example the ceramic three-way catalyst or the diesel oxidation catalyst.
Can you supply a shape that is not in the specification tables?
The tables show the universal specification and size. Send a drawing by email and our engineers will confirm whether it can be produced.
