Permanent effect of the speed glue. Is it ever possible?

Speed gluing is a messy job, you know. Japanese scholars did suceeded in developing an innovative sponge material to retain SG effect for years. In essential it is a pressurized foamed material with closed oxigen capsules, -no obnorious odours of benzine, no health hazard at all.
Each single capsule works like an inflated rubber balloon, having inside air pressure over 1 atmosphere.

Be happy.

Be happy that these rubbers didn't make it out there.
There were terrible.
Glad Stiga made Mantra very quickly to fix the problem of these rubbers

All these "high technology" buzzwords from different manufacturers but they still can't leave a bigger impression than Butterfly's 'Spring Sponge'

Where did the oxygen come from that that filled the gas pockets? I can see normal air in in the gas pockets.
How did they get the gas pockets to have a pressure over 1 atmosphere? Before the foam solidified the gas would expand to reach equilibrium with the air. Getting the gas pockets to be a uniform size is a trick.

BTW, it is the gas pockets that are "springy", not the actual foam rubber material itself. You fill your tires up with air not foam.

I'm not sure what is worse
These buzz words or 10 year old failed technology that Igor is posting about today

Airoc didn't even need to compare with Butterfly, it couldn't even compare with its own "older generation" rubbers.
Calibra Tour was also bad.
I guess the oxygen in that Airoc wasn't suitable for earth
The only good of those Daiki was Calibra LT series and then moving onto Mantra.

I suppose if we pay enough money we could make a sponge that's filled with high pressure gas locules. That's theoretically possible. I wonder if that may be the market in the future, a $500 sponge with $30 replaceable topsheets.

Donic Baracuda tag line was and I quote, " rubber with inbuilt speed glue effect produces fantastic spin "

Does this count?

Baracuda was my very first ESN / 1st Gen Tensor rubber I used. Fond memories I had with this rubber paired with Tibhar's Stratus Powerwood ( both side ).

Everything wears out. Foam cushions you sit on lose their spring. Same with TT sponge. Also, any gas in the air pockets will eventually equalize with the atmosphere. Balloons lose air and go flat. Air mattresses go flat. Tires go flat.

There is another thread about the first feeling playing with T05. I don't remember that but I do remember the rubber felt mushy at the end. Also, H3 Neo top sheets seem to last forever but the sponges do go dead over time. I probably play with my rubbers for too long before I give up on them.

Everything degrades over time.

back in the day (1970-ish) when mark v and sriver came out, and were noticeably more lively than any other rubber sheet especially in the first week, we were told that an inert gas was present in the bubbles under pressure so that the sponge sheet became a component that added speed, as well as aiding spin strokes. The slowing down of the rubber over times was attributed to gas leakage over time.
I would have thought an inert gas was more more likely than oxygen
with apologies to BB:-
If the above is true, then the manufacturing process is a mystery. Perhaps they found a way for the manufactured sponge to cool while containing bubbles which contracted around the gas in them so creating slight pressure and tension
