Sorry, don't know of anything more recent. This covers: HP sodasorb, Agasorb, Diveasorb, Draegersorb, and Protosorb

Ass allways Gene, you provide a wealth of information. Though it does not cover Molecular Products, it is worth reading.

Thanks.

Great info a usual! Knowing some of the heavy regular AGAsorb users it seems to be designed with low temp performance in mind. If I'm not completely wrong I think the AGAsorb is actually made by Molecular Products?

If the sorb behaves anything like chalk then I expect the damage to be of a mechanical nature due to some forming of ice crystals.
It will give you more dust. Wether thats noticable remains to be seen. The water content is low and there are many pores than can hold minute crystals.

If you can't avoid freezing then make sure it remains frozen until you use it.
Repeated freezing and thawing will make it worse as ice crystals form every time.

In addition if you have any control over the freezing rate avoid slow freezing as less but bigger crystals will form.
