Diesel heater burner mat

[Whaup367]

Hi,
I have a Webasto diesel heater which is working fine but parts are getting hard to find. One of the service items is the burner mat, which (IIUC) acts as a reservoir for the fuel by soaking it up before it's vapourised and burnt.
The OEM part is this: https://www.butlertechnik.com/item/Webasto/HL32-Burner-Matting-1319261A-117835/6R4

...but they are getting hard to find and expensive.

It looks like a shaped piece of thinnish fibreglass matting which doesn't seem as if it should be hard to find in sheet form and cut to shape...though I'm guessing the density of the mat may be important(?).

Anyone know where I should look for this type of matting, please, and/or what it would be called when it's not a specific "part" of an obsolete device?

Thanks!

Is the same part used in China Copies ? maybe checking out Vevor and other brands may be OK

Good thinking (and thanks for taking the time to reply) but I think these are copies of later, Eberspacher, models, and use a different burner setup. Even the later Webastos seem to have a separate burner cartridge, rather than a combustion chamber with a replaceable mat :-(.

What about scrapped cars that use Webasto .. or truck dealers ... they have Webasto often for the cabs...

I would bet dinner it is mineral wool, not fiberglass, which would melt.

I looks as simple as a shape punched from mineral wool insulation matting, although the ones I'm seeing are thicker. I'm sure a brief search would find it. This is the sort of material used in stove cartridges.

Unless I'm misunderstanding the nature of these things, it's more of a consumable than a "part" which might break or wear out: the mat appears to me to operate a little like a wick (though I don't think it's quite the same process) and so ends up contaminated and degraded, hence the need for regular replacement.
My thinking is that these are just pre-cut examples of a generic material, made to fit this application, so if I can source a sheet or other larger piece of this stuff, I can keep the unit going in the absence of the OEM supply...
It looks like fibreglass insulation, a few mm thick but seems possible that the density and thickness are important to get the vapourisation rate right for efficient burn. I just don't really know... might not really matter and maybe a lump of loft insulation would do the job fine!!
... so I'm hoping there might be someone here that can advise...

I've bought a new one for my Webasto Thermo 90 from Ebay. Chinese sourced I think.
Seems to be made of some sort of compressed fine wire matrix
