Applying cyanoacrylate to some natural materials such as cotton (jeans, cotton swabs, cotton balls, and certain yarns or fabrics), leather or wool results in a powerful, rapid, exothermic reaction. This reaction also occurs with fiberglass and carbon fiber. The heat released may cause serious burns [34] or release irritating white smoke.

Although it is thermoplastic, polyacrylonitrile does not melt under normal conditions. It degrades before melting. It melts above 300 °C if the heating rates are 50 degrees per minute or above. [12] Glass transition temperature is around 95 °C and fusion temperature is at 322 °C.
For rigid containers (like ice cream cartons, for example), covering the surface of your food with a layer of plastic wrap helps keep at least some of the freezer burn at bay.
