What is Matrix then? All the MSDS says is 100% Natural Made Stone. It has all the properties of Pumice, It's highly porous, very lightweight and some even floats like some pumice, and it is colored like common pumice.
Yes, it's pumice. Pumice is a generic form of volcanic rock whose ingredients may vary.
The difference from buying pumice in a store versus Seachem is presumably that the store won't clean it and guarantee that it's free of heavy metals. (Since pumice comes from volcano's, it will have different properties (ingredients) depending on where it came from.)

The nursery across the road from my house stockpiles pumice by the dump-truck-load. I have often thought about washing some of it and trying it out, now I will definitely have to give it a go....
