Maximum Temperature
The most common question asked when selecting an advanced filament is “What is the maximum temperature <plastic> can handle?” While the question is reasonable, it is completely unanswerable.
Broadly speaking, the higher the temperature rises, the weaker the plastic becomes. This often happens gradually; therefore, the higher the strain in an application, the lower the “Maximum Temperature” is considered to be.
Some plastics also exhibit creep, a situation where a plastic component slowly deforms in response to continuously applied force. This effect can also vary with temperature.
Takeaway
Identifying the “Maximum Temperature” of a particular polymer for a particular application is non-trivial. While datasheets or HDT testing can provide critical inputs or points of comparison, no one number is likely to provide directly applicable data for your project.
