I already gave two options and ask about the appropriate sequence (method) to use!
There is 3 possibilities and the answer would be: option 1 - option 2 or other.
I ve never ask about a thesis on the subject...nor the reasons of shrinking that I already know.
Sorry, i read my question again...
Patprimmer,
Regardless of the environment and use conditions. The question is not to know the reasons of degradation of the polymer. I just want to know what are the "correct" mechanical tests to perform in order to degrade the material severely and quickly.
I also want to know the theory of...
To simulate ageing and degradation of a plastic material PBT containing 10% of glass in the lab, I am trying to run humidity, wetting, and drying processes. From samples
gathered from the field this material have had cracks appearing in the finished assemblies. This material is suspected to...
I'm planning to use aluminum (Grade 6061 T6 / 6082 T6) for low temperature equipment skids (-20 to -40 degC).
Are there any recommendation / limitation for these materials at such low temperatures (resilience...) ?
Thanks and regards,
According to the link below the styrene leaches into the drink whether the beverage is hot or cold

I thank Sheilah Etheridge for this link.
I never used them. Now, I must prepare a safety meeting and explain to my collegues that those cups are harmful, but I did not have enough information.
I agree with all of you, not all cups have the similar behavior. Actually, I dont know the composition of the cups, I only know that they are used daily by all employees in the company where I work.They add boiling water and the cups become deformed. These cups are like ones used for drinking...
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).
