Wanted to test this theory out.
Since rubber degradation has a lot to do with oxidation, why not just remove the source of oxygen and simply store it in a vacuum bag? Has anyone tried this before?

I didn't but this is a very good idea for the people seldom playing. For those who train, their play may destroy the rubbers before any oxidation has a chance to kick in however the price of a vacuum bag is nothing compared to what we spend on rubbers so why not since the benefit is not null and the routine is easy to install?
You may go further and introduce an anti pressure box maybe? (btw did that thing ever work LOL) Edited by stiltt - 07/28/2022 at 5:08am |

I had some rubbers at the start of covid put away and they didn't do too well (small amount of oxidation). Perhaps I should have gotten fresh clean bags. Also some rubbers shrunk a lot. So the bags don't help that part. I don't know what to do with small rubbers that can't be play.

Were they all vacuum bags?

Storing porous sponge in a vacuum is not a good idea because of permeation.

Adhesive protection sheets work very well and are simpler to use.

Could you elaborate? I'm not too sure if I understand....

These protect the topsheet, but doesn't prevent the sponge itself from hardening. I have like a 4 mth old D09c which is becoming close to unplayable fml...

To keep it short, the pressure difference will cause the gas within the cells to escape to the void between the topsheet and sponge at a faster rate than it would if it were stored at atmospheric pressure.

I can't think of a practical method to keep your rubber from oxidizing. Most people don't have a convenient source of nitrogen or argon at home. I think zeio is right that a vacuum would deflate the sponge, but maybe you only need a slight vacuum? Maybe there is a middle ground somewhere?

Maybe some boosting will soften it up enough? It just doesn't produce that insane spin it did for the 1st 3 months.... I have a decent job so I don't mind that much

Would this ruin the rubber though, isn't this a reversible process?

Yes you're right, but in my experience the degradation of the topsheet is usually far worse than the sponge. When you buy a new rubber, most are in a plastic packet that's got a few holes in it, so I can't see how degradation due to oxidation can happen that quickly.

Possibly irreversible if it damaged the walls of the pores in the sponge?

Update on this - I stored my racket in a vacuum storage bag (with quite a decent vacuum) for a week. I opened the bag and played with the setup yesterday night.
Some thoughts: 1) It definitely felt very different - the vacuum process did quite a number to the rubber. This almost feels a bit like boosting the rubber as the rubber felt very elastic and lively (it was going increasingly dead on me). I was getting some insane spin, even more than usual... 2) However there seems to be a reduction in the sweet spot area - I think the vacuum process somehow caused some glue detachment on the sides. Ideas on why these have happened?

I bought a goon looking bag you were suppose to breath c02 into (silly gimmicky thing from butterfly I think).
If you use tacky rubbers especially buy some contact, nothing restores and cleans it better after whatever else you use to get the first visible stuff off. $2 a roll If it's your playing bat just put it in a case... or storage if you are worried about the sponge a sandwich bag. As I have mentioned before, for me the most noticable difference of the sponge feeling dead when you play is when its cold. So keep it under your shirt for a while before competition. Not much else you can do... And or reboost it... But I reckon we damage them every time we pull them off and put them down again. |
