Ford's New timing Belt in Oil information 1

[Ve3nNo0wM]

I recently got super interested in Ford's Bi-turbo and found heaps of information about that and then discovered they're using a "belt in oil" in which i have found very limited information about.

Ford is claiming the same lifetime durability of a metal chain timing belt, using this Glass cord / rubber hybrid material using a special Bonding method.
The following pdf gives lots of information on the company that makes the belts, but doesn't talk specifically about the "belt in oil" that Ford is using.

Can anybody shed more light on how the heck they got a rubber compound to survive in oil for the same lifespan of a metal chain ?

also, this is my first post and i hope i picked the right category, otherwise feel free to move it accordingly.

There's no real mystery to it- they are almost certainly using a nitrile-heavy HNBR formulation for the polymer components of the belt.

Manufacturers in Europe have been doing the wet belt thing for going on 10 years now, this isn't a new concept.

hmmm, ok. There's still a finite life of these belts then. according to

https://www.azom.com/article.aspx?ArticleID=537

they typically last 100k - 200k.

I just couldn't believe the notion that they could last as long as a chain and it completely threw my understanding of the properties of rubber in oil.

oh well, if it sounds too good to be true... it probably is.

there's no other possibility ?

With elastomers you basically have two options, does it stand up in water or does it stand up in oil.
Rubber compounds (and fillers) that tolerate oil exposure are very common. Think of the hoses in hydraulic service.
The only rubbers that will work in both environments are very expensive.

I downloaded the owners manual for the 2018 Ford F150 and in the scheduled maintenance there is no mention of a replacement interval for the timing belt. There is no mention of the timing belt at all. My experience with dry timing belts is they typically had a replacement interval of 60,000 miles (100,000 km). Given the disastrous consequences of timing belt failure the service interval is usually prominently highlighted.

They didn't mention anything about Firestone 500 tires either...
