Disintegrating rubber bands
 

What's happened to rubber bands? About 10% of my mixed stock are in
various stages of decay. I suppose this is something to do with being
eco friendly, but it means I can't trust them any more for holding stuff
together for more than a few weeks.

Can you still buy good ol' rubber bands? What's the decay process of the
eco ones - does they decay from manufacture or is it initiated by the
first stretch?

On my experience the old ones used to do what I can only describe as 'melt'
and stick to everything.

Modern, presumably plastic, ones keep good for years.

Light doesn't have a good effect on the old ones.

I'm guessing at the decay process, but natural rubber is stabilised by a
process called vulcanisation, whereby sulphur creates cross linking between
the rubber molecules, stabilising them. Remove that sulphur, maybe by a
process of oxidation, I don't know, and possibly a stcky natural rubber is
the result again.

Just a guess,

Andy.

You're right but I didn't want to show off :-)

I pick up from the pavement the ones dropped by the postpeople.

Me too; but they're just as bad as Phil's - when you want to use them,
they've gone all manky :-(

They've changed recently from 'natural' colour to pinky-purple.

Owain

Have they?

Could it be because the weather's turned a bit nippy and they are still
wearing their shorts?

The best place to harvest them is the car park of our local delivery
office, near the bike racks.

There were loads of complaints from the public a while ago about
posties dropping rubber bands all over the place - Royal Mail claim
that they are now bio-degradable.
(Which of course doesn't mean that they aren't unsightly and dangerous
to pets.)

Thirty or forty years ago rubber bands seemed to last for ever -
nowadays it would appear that they're only intended for very
short-term use.

Yours would be too, if you were still wearing your shorts in this weather.

Oh no. You should treat yourself with more respect than that...

The UV light degrades them. Leave one on the window sill for a few
weeks, and it will just crumble..

Ours changed to those years ago - they're very good. Too good - I have an
overabundance.

Our postman is stll wearing his red T shirt and black trousers, he's a very
fit young man. He's also regular, friendly and gets things right. But I
daren't tell the RM management that or they'll take him off our walks (he
does two). They did that with the last one I commended. We've had a
miscellany of awful postmen :-(

I doubt there is much difference in the way that elastic bands are
made. Perhaps they were made of natural resin originally but whatever
they are made of these days will be the cheapest available suitable
material as suits throw away items that they are and have always been.

I think the OP's problem is that his bands are now in contact with
something that perishes them, chlorine or oil based most likely.

Our postie, Wayne, is still in shorts. He reckons that if it's very cold
it makes little difference when you're walking fast, and when it's
raining you don't feel as wet 'cos you ain't got wet trousers sticking
to your legs.

Yes, but his name *is* Wayne......

I imagine the first is true (I can't walk fast) but I certainly endorse the
latter point. When it rains - if it's warm - I shed clothes rather than put
them on. Skin is waterproof.
