(OP)
Which kind of artificial rubber with high tear and abrasive resistant should I go for in order to produce items with similar properties to shoe soles and tires with a hardness over shore A-80?
It needs also to have good bonding properties to metals.

I need to get some good polymers from somebody who sell these in bottles. Any suggestion about any good web dealers?

RE: Need advice regarding artificial rubber.
There are multitudes of companies who do this at the professional level, reasonably priced, with consistent and repeatable results.
If you have a very high volume part, then you can justify going it to it on a grand scale.
Good luck.

Nitrile rubbers have higher tear strengths than urethanes (in general) and good abrasion resistance. They hold up better to a wider range of environments also. There are about a gazillion choices of "artificial rubber" compounds to choose from, and we've suggested two. SBR rubber is a common tire compound. EPDM can be compounded to be quite hard, and is very stable chemically. Butyl rubber can be made quite hard, and has the best impermeability to gases. Silicones...don't get very hard.
Any heat-cured rubber will bond well to metals, provided that you do your homework and find the appropriate bonding primers for the particular metal and rubber combination. One of the best ways to learn about rubber is to go visit a rubber molding shop and ask questions.

btrueblood, my experience (and quite a few references I've seen) is that urethanes generally have higher tear strength than nitrile rubber, and not all urethanes are "too slippery for a shoe sole". Castable (liquid) urethanes are generally slipperier than millable (rubber) urethanes. Urethanes are used today in footwear and shoe soling.
