Plastisol inks will not dry, but must be cured. Curing can be done with a flash dryer, or any oven. Most plastisols need to reach a temperature of about 180 degrees Celsius (350 Fahrenheit) for full curing. Plastisol tends to sit atop the fabric instead of soaking into the fibres, giving the print a raised, plasticized texture.
where is the heat released up to a certain time , ˙ is the instantaneous rate of heat and is the total amount of heat released in , when the reaction finishes. [ 9 ] Also in this case the degree of curing goes from zero (no bonds created) to one (no more reactions occur) with a slope that changes in time and has its maximum about at half of ...
It is distinct from thermal-oxidation, which can usually take place at less elevated temperatures. [3] The onset of thermal degradation dictates the maximum temperature at which a polymer can be used. It is an important limitation in how the polymer is manufactured and processed.
Due to the large amounts of heat given off by internal combustion engines, [3] heat shields are used on most engines to protect components and bodywork from heat damage. As well as protection, effective heat shields can give a performance benefit by reducing engine bay temperatures, therefore reducing the temperature of the air entering the engine. [4]

Left: individual linear polymer chains Right: Polymer chains which have been cross linked to give a rigid 3D thermoset polymer. In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (). [1]
• Heat blisters can form after a burn or sunburn, Dr. Patel says, and blisters can occur when you get frostbite in the extreme cold. You might also get blisters from allergic reactions or ...
