Yes, chitin does have a melting point. The melting point of chitin can vary depending on its source and purity, but it typically ranges from 200 to 250 degrees Celsius (392 to 482 degrees Fahrenheit).

Yousra Mdarhri

Chitin does not have a melting point.

It begins to degrade at a temperature over 200°C.

For more and exact information, here is an article about chitin thermal degradation :
