Properties of foam plastic in Mattress and in general

AI Thread Summary
Foam plastic, commonly used in mattresses, has specific properties that affect heat retention and insulation. Hot foam retains heat more than cold foam, which can lead to discomfort during sleep. The insulation properties of foam can vary, with some types retaining heat more than others, potentially influenced by the mattress cover as well. The discussion highlights a concern about foam's ability to insulate too much, leading to overheating. Recommendations for mattress types that balance comfort and temperature regulation are also sought.

Hello,


I wanted to know which properties a foam plastic have in general and how it works in a Mattress.

I have a Foam mattress is there any difference between hot and cold foam?

My Mattress is a Foam mattress not a Spring mattress and it feels too hot after a while you lie on it.

Is it because of the Foam it gets heated and doesn't give away the heat?

So can it be that the Foam insulate too much? or do a Foam not insulate and its only the cover of the mattress?

Thats why i wanted to know the properties of a Foam and of the Foam which is filled in a Mattress or in General.

Does Foam insulate and how it is build or works.

Can you also give me a advice which mattress should i buy which are the best in tests and experience ?

Thanks!

hi,

this is all about memory foam I am talkin about normal foam made of the same material as like plastic ...i wanted to know about the insulation of foam and heat conduction properties for example.

anyway thanks for your answer.

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
