Melt Temperature
Materials Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Melt temperature (Tm) is the temperature at which a crystalline polymer transitions from a solid to a liquid state upon heating. It is a critical parameter for processing thermoplastics by injection molding or extrusion.
Example in context
“The melt temperature of polypropylene is around 160°C, which must be monitored to prevent thermal degradation during extrusion.”
“Polipropilenin erime sıcaklığı yaklaşık 160°C'dir ve ekstrüzyon sırasında termal bozulmayı önlemek için izlenmelidir.”
Where engineers use it
Melt temperature is essential for determining processing windows in extrusion and injection molding. Engineers use DSC to measure Tm and ensure polymer does not degrade during manufacturing.
Synonyms: melting point, Tm
Practice: can you use “Melt Temperature” at work?
You are a production engineer troubleshooting a smoking extruder. The melt temperature sensor reads 20°C above the polymer's specified Tm. What do you do?
Show a model answer
“Set the barrel temperature below the melt temperature to avoid burns.”
