so i want to ship something in a styrofoam container. 7x7x7 .5" thick styrofoam 1day express.

i want to ship something at room temperature 75F, but the temperature outside is 32F. how long will it take from 75F to 32F?

anyone have a heat dissipation per hour calculator through expanded polystrene foam?

will depend on what you are shipping as well. also what temperature do you need to keep it at?

what environment is the container in?
would have to know more variables

cialda // i want to keep it above freezing. It is 75F now in TX i want to ship it to Ny but it is 20F there.

saber_x3 // it is in a 7x7x7 box with a .5" styrofoam liner.

if you're worried about it actually freezing, i wouldn't worry so much. environmental temperature generally has to go below 32F to freeze anything since it involves a state change, and it's even harder if it's moving even the slightest.

i would wrap it with bubble wrap good. the more you fill the container the better.

i think for the most part it will be fine. i receive shipments occasionally and they will be overnighted as well but on ice packs. when i get them, they tend to be close to or above freezing.

it will depend more too on what you are shipping, its heat capacity, the exact flight conditions, and so forth.
