Are the PS gobelets dangerous for the health?
(OP)
I would like to obtain some information about the hazards related to the use of PS (polystyrene) cups or gobelets for hot drinks.These cups are deformed when we add a warm water (temperature above 90deg C).





RE: Are the PS gobelets dangerous for the health?
http://en.wikipedia.org/wiki/Polystyrene it has a glass temperature of 95ºC.
Since you've already demonstrated that it's unsuitable for hot drinks and you presumably won't do it again

It is quite difficult to add hot water to a cup, add othere components to a beverage then stir and maintain over 90 deg C.
I have used PS cups in such application for years with not a single cup failure. Maybe some reasonable technique re gripping force is required.

I believe such cups are used the world over in coffee vending machines. I can only assume that they add the milk first to lower the water temperature or they may avoid such high temperatures. Afterall what's the point of 95°C water when it's not comfortable to drink it at that temperature.

I only want to know if the cups are harmful. I heard of they release some toxics.

Frankly, I've done it exactly once, with an orange juice bottle, that deformed with hot tea. So, I've never done it again. I'm puzzled by why you'd continue to use something that's clearly inappropriate for the application.

This article measured sytrene from injection molded parts and it was well below regulated limits even under the worst conditions:

Best of all is this study that really measures leaching of styrene from household PS cups etc. It shows there is some leaching but in the ppm level:

Why did you write 3 posts before you declared your agenda.
With complete information we can cut to the chase with minimal delay, and thereby save everyone some time.
The cups are designed for drinking, therefore the water should be at a temperature that is safe to drink.
If necessary, add the hot water last and do not pick the cup up until the contents are mixed and at near consumable temperature. Do not add water at a higher than required temperature no matter what the cup is made from as there is always a risk of spill, even from a metal oe ceramic cup.
Demon3 already fully answered the styrene monomer extraction issue.
