Matt, could you keep an item made of rubber inflated for a long period of time?

Cheers matt,
i had my suspicions that this could be not a good idea! Seen what resembles a pioneer boat and thought that it would be quite a good thing to display my pioneer in but i'll have a good think about it now

Does Silicone oil also stop rubber that has started cracking and going (well for a lack of a better word) gooey ? I have a british gas mask that was sticking to the box in part when it arrived. Would never have brought it if I had seen how bad it was first but if I can save it I would like to.

Cheers

Nick

Hi Matt

Thanks, Let me know how it goes, (before and after pics might be interesting?)
I might put some talc on this gas mask in the mean time see if it slow down the process.

Cheers
Nick

Keep sunlight and cigarette smoke away from old rubber. Had a friend who constantly smoked at WW2 oxygen masks in his collection. Within a few years, his started to crack and crumble, while mine stayed factory fresh. He's liable to get cancer too.

Silicone seems like a good idea. Automotive stores here sell Armorall, its a restorative for car tires and dashboards, IIRC, its silicone based. Makes my dash look great, feels a bit slick for a few days tho!

I've read,heard...,that natural (old) rubber should be treated by talcum powder only and that nowadays "un-natural" rubber should be treated by both talc or silicon products ,because not all rubber products are the same...

Lucky..,
I know someone who bought a Luft O2 mask in good condition and after a while it started to crumble,what a pity,it was a early type

...,this man was a non-smoker and the rest of the family too...,he also kept it in the dark..
I think it might have something to do with enviroment,temperature,whatever..,but on the other hand he owns another 7 O2 masks and they're still fine...
Think it's something starting from inside,a certain process caused by ???

Bottomline:
All old rubber items are tiny timebombs,don't invest too much in these,it's only a matter of time !!
But what we've we've too treat,that's a fact..

Jos.

Thanks again, Seeing as this mask is a pretty common british one I might try both in parts and see what happens (Not going out to destroy it, It's doing that itself, could be an interesting test piece),
Cheers for the update

Silicone oil is good for items You want to use some time again, but for a collection of rubber made items it's better to store them into a sealed display (an old fish tank f.e.?) and use then a special oxygene absorbing chemical inside the tank as oxygene is the main agressor.
