Positioned as the de facto standard for next-generation flame-retardant PBT resin, the product complies with the world safety and environmental standards, employing a non-halogen flame retardant to achieve the highest V0 retardant level set by the Underwiters Laboratories.
2. EXPERT ANSWER. Evaporation is an endothermic process. The reaction in which heat is absorbed by the system is known as endothermic reaction. In evaporation heat is absorbed and passed to the water which forms vapor when heated. Posted by Krishnakoli Datta on 30/5/13.
Endothermic reactions absorb energy from the environment, while exothermic reactions release energy to the environment. Distinguish between endothermic and exothermic reactions. 1  All chemical reactions involve the transfer of energy.  Endothermic processes require an input of energy to proceed and are signified by a positive change in enthalpy.
