Super Bowl and Super Balls

Most of us had one of these as kids. At least some of the older ones.

My mechanical engineer has suggested putting a thin sheet sheet of polybutadiene my blade. It isn't legal to put the top sheet directly on the blade unless it is short pips but it would be fun to try. If you want maximum spin and speed this what you put on the paddle. Put a 0.4mm sponge underneath just to be legal but not to absorb too much energy. For starters I would probably just glue the polybutadiene sheet directly to the blade just to see what would happen.

So polybutadiene has been around for years, before Sriver and Mark V. I wonder why the TT manufacturers never made a rubber out of polybutadiene if they really wanted faster and spinnier rubbers. My feeling is that the polybutadiene top sheet would need to be thin and would wear out quickly or get brittle. The other is that no one would be able to control it.

The question I have is what are the TT manufacturers trying to sell us? There are many hundreds of rubbers now. Most are pretty much the same yet each new one is supposedly spinnier and faster than the previous and sold at a higher price.

The only source I have seen is Alibaba but the minimum order is 500 sheets.

My mechanical engineer told me of a sponge or rubber called sorbothane. It is the opposite of polybutadiene. sorbothane absorbs energy and would be a good anti sponge. It comes in 7x7 inch sheets with or without a glue sheet and in thicknesses of 1 and 2 mm. This company specializes in damping.
Now add a slick top sheet and the rubber should be able to compete with the best Der Materialspecialist or Dr Neubauer can provide.

I am still searching for the super rubber.
