this is confusing at the beginning.
You did a great job of explaining the details. The problem is that most of us common folk think that rubber is rubber, and if it is not you will call it something else. Using the same word for two entirely different things is problematic. manufactures are calling this Premium Rubber, which now does nothing to explain what you are doing here.

It is like Calling Rum for Vodka, based on the logic that the most common attribute is alcohol, and you want to get drunk. If the taste is what is important, and the user does like rum and does not like vodka, the difference is what is important, not the common.

I did not want a rubber hose. I did want the attributes of this product, and rejected it because it was called premium rubber. Confusing and not helpful. Words mean something. Not explanations. The industry needs a word for it.
