The liberation or evolution of heat during the curing of a plastic product.
The heat released as a by product of some chemical reactions. All flexible polyurethane foam production reactions are exothermic.
The amount of surplus heat produced during a chemical reaction. Materials such as resins which produce heat are refered to as exothermic.
heat generated by a chemical reaction.
Exothermic materials give off heat when they cure. When large quantities cure all at one time, the amount of heat given off (the exotherm) can be high enough to melt plastic containers.
The liberation of heat energy during a chemical reaction. Exotherm is increased in large masses.
1) The temperature/time curve of a chemical reaction giving off heat, particularly the polymerization of casting resins. 2) The amount of heat given off. The term has not been standardized regarding sample size, ambient temperature, degree of mixing, etc.
The amount of heat given off by a chemical reaction, proportional to the mass.
