Why Are Thermoplastic CV Boots So Hard To Find?

[Fitz98]

After many hours of research, I came to the conclusion that most aftermarket CV Boots are junk and won't last long. At least that is the general consensus that I have found. Enough negative reviews to make me want an alternative, otherwise I would be wasting my time and would be doing the job again in short time.
It seems that most approve of Thermoplastic boots.
If they are so much better and last so much longer, why are they in such short supply? Wouldn't it seem logical that since the biggest complaint in the aftermarket CV world is the longevity of the boots, that it would be a good idea to make thermoplastic boots and charge a few dollars more for a much better product?
I literally could only find 2 international companies that make them and 1 company that stopped making new boots in 1999 recommended by @Trav....at least for my vehicle.

Does OEM have a CV rebuild kit? That saves money but usually gets good boots.

Febest? Rockford

I would suspect the best CV boot material is known as Hytrel which is a Dupont patented product. So only OEMs with deep pockets are willing to pay the premium to use that.

The patent expired years ago, so that's not the reason.

I still maintain there must be different quality levels of neoprene, so just saying "neoprene" is disingenuous and confusing.

We can probably all agree most ratchets and wrenches are made from "tool steel." And yet 99% of us also understand the metallurgy varies. TTC has proven HF will be less consistent in metallurgy than SnapOn.

So, why is there not "rubberology"?????

It would explain why OEM "neoprene" seems to last A LOT longer than Trakmotive, and many unwanted pregnancies as well......

Don't use Trakmotive condoms! DUH!!

Most OE boots are NOT neoprene, but rather thermoplastic elastomer (TPE)
Some newer cars have neoprene inner boots, but the outer boots are still TPE.

Exactly, everyone keeps insisting Subaru used neoprene inners. I don't know.
