English term

English
Tech/Engineering
Engineering (general)
(sponge rubbers)
The term is used in a packaging machine manual.
This is what is said about the sponge rubbers that hold the bag during the process:
"When these sponge rubbers become damaged, worn or dry-rotted, they should be replaced."
I know that sponge rubbers can in time become brittle or hardened (or both), but I am interested which one is the meaning of dry-rotten or does it mean both.

brittle from drying out
I found a few discussion of dry rot and rubber on university websites. There are also discussions to be found by auto mechanics about dry rot in tires. They all seem to talking about brittleness that occurs because the rubber is drying out.
"Dry rot of rubber or cracking of plastic caused by sunlight
Sunlight can cause dry rot of rubber or cracking of plastic"

"Tires need a minimum amount of 1/4" of tread (check with your state Division of Motor Vehicles for the measurement); they should be adequately inflated and have no signs of dry rot cracks. Spare tires also should be checked."

AND FROM A WEBSITE ABOUT AIR CONDITION SYSTEMS and the rubber nozzles:
ACBs (active chilled beams) equipped with rubber nozzles may need to be replaced as a result of dry rot within their service life.

I am not an expert in the field, but I have been checking University websites, and this does seem be the same type of context as your text -- talking about rubber degrading and losing its elastiscity as well as cracking as it dries out.

dry rot. Look for a code (usually found on the sidewall of the tire)
that indicates when the tire was manufactured"

To go back to your question: I think the answer is both, brittle and hard. Rubber as is dries becomes hard and loses its elasticity, and also becomes brittle.

Thanks Tony ! I would hate to driving with a tire that was really damaged in this way.

Am just offering help with the English :)
Hi Timo,
Dry rot is a little different from being brittle or hardened - it is to do with damage caused by a type of fungus. Have a look at the links below.

English term (edited):
dry-rotten
frayed, torn,
As is the case with the sponge you use in washing up. in time they become 'frayed or torn or worn-out'. Not very technical, but similar situation in your machine.

crumbly
That is how I'd describe the rather unpleasant mess that sponge rubber gets into when it dry-rots.
