Additives and materials for swimming pool noodle

[hamsuplo]

Swimming pool noodles don't absorb water and are resistant to chemicals in the pool.

I have a protective foam tube supplier, whose products deteriorates within weeks in exposure to UV light, but I have swimming pool noodles that seem to last forever.

Since they are both foam I would like to know what material the swimming pool noodles are exactly made of an additives that make it last long, if anyone has experience which swimming pool noodle manufacturing.

Thanks in advance

The foam tube (ie:foam rubber grip?) is likely foamed rubber. I believe noodles are foamed polyethylene.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

I would dispute that foam noodles "last forever;" I've seen foam noodles left outside that show at least gross discoloration.

Have you looked at the foam insulation used for household A/C insulation? The insulation around the lines going to the outside heat exchanger at my house have been there for 6 yrs and look tolerably good.

It's probably the same polymer just one is UV stabilized using additives and the other one not. That can make the difference between 1 day life and 20 years.

Contact a polymer stabilization expert like Stabilization Technologies or

or ask a supplier.

We used stabilizers in our compounding of PVC resin back in the early 70's to protect the end products from UV rays deterioration.
