I'm mechanical engineer, so the topic of material definition pertaining to polymers isn't my best.
I'm searching the maximum "service" temperature of a few polymers and elastomers on Campus plastics and Matweb.
Some compounds have a clear "service" temperature window other not. So my questions are:
I'm searching the maximum "service" temperature of a few polymers and elastomers on Campus plastics and Matweb.
Some compounds have a clear "service" temperature window other not. So my questions are:
- Is a fraction of the fusion temperature (1/3, 1/2 or 2/3...) a good estimation of maximal "service" temperature? If yes, is there a common knowledge among material engineers on that fraction?
- Is the deflexion temperature at 1.8MPa or 0.46MPa a commonly used limit for the maximal "service" temperature? If yes, is it a fraction of this temperature?
- Is there any other possible rules of the thumb or known relations between other properties to calculate a maximum "service" temperature?
