The company is not standing still and still has a real chance of success with the Polish litigation. Watch this space!

Looks like this is the old Praire Maining, for now they're doing copper exploration.

More companies to add yet. Just a thread to list, and possibly discuss those companies that may be making a breakthrough to commercial production, or supply of equipment or products to commercial levels.

It's a bit of a hidden market at the moment as many don't realise that graphene composites are upon us and will transform the composites market.

(note the video on the website, this explains the applications, improved performance.

EG they claim body armour enhanced with graphene platelets, would be the equivalent of 6 inches of armour plating.
Support structures meaning buildings could be 3 times taller and so on.



I will add in the various companies but one key theme seems to be obvious. Some make very big claims.

Quite simply most are all about introducing graphene nano-platelets into composites, be it tyres, sports equipment, military and automotive etc. The uses are vast and are in countless items we use today.

It equates to much higher strength for the same weight, all the way down to equal strength with much less weight.

Take tyres, less rolling resistance and higher resistance to cuts and damage. That isn't the future one company is already working with a cycle company and we know how the cycling industry wants faster, stronger and lighter. Head already have it in their tennis rackets.


However there is specific set of circumstances that will see some companies rise above the others.

3 points.

Purity.

I don't see companies having too much of an issue on the purity side. That said there is a huge difference in performance with the range being Carbon black up to pure graphene

What are graphene nano platelets?

They come from top down and bottom up production.

Bottom up means produced from graphite sources. Top down can mean produced from Hydrocarbons (AGM do this).

A loose definition of graphene nano platelets is platelets consisting of 10 layers of less.

Now that's where a major point kicks in when looking at the companies involved.

NOTE

In that Graphoid video they talk of 'multi-layer' graphene, and 2% graphene means much greater strength and performance for the composite.

If you have 10 layer platelets at 2% compared to single layer platelets at 2% then that tells you in volume terms, there will be 10 times more platelets available in the single layer version.

That means the dispersion efficiency will be far greater with single layer meaning a higher performance.

So you have your platelets of high purity, but it doesn't end there. You now need technology that will efficiently mix the platelets into the composite. The better the dispersion rate the higher the performance. So you need excellent dispersion technology to achieve the best performance of the material.

If you mix gravel into cement instead of sand you don't have a very good dispersion level, there are big gaps in the mix, and you have a very poor mortar.

So what we have is quite a few companies talking about bulk production of graphene nano platelets, but if you look they are all multi-layer producers.

What few mention is if they have dispersion techniques or not, so some may be able to supply the nano platelets but not he technique or know-how to mix the graphene into composites. That's what end users need, they don't know how to do it either.

So the best platelets and the best dispersion technology is the key.

The best being

HIGH PURITY

SINGLE LAYER PLATELETS

HIGH PERFORMANCE DISPERSION TECHNIQUES.

Obviously on the technology side patent protection is key for value.

In this link you can see photos which gives a quick visual impact of having the right dispersion technology (Haydale tech)
