Avaliação da compatibilidade química do epóxi LY 1316 com o fluido refrigerante R410A.

This work had the main goal of investigating the behavior of a thermoset polymer, epoxy LY 1316, making a survey of the chemical compatibility of this material in the refrigerant fluid R410a, currently used in air conditioning equipment, so creating a methodology that evaluates different polymers. The operating conditions of the system were simulated by immersing samples in liquid R410a for a period of fourteen days, according to the ASHRAE 97 standard, then the effects of this immersion on their mechanical and thermal properties were evaluated. A control group was created in order to evaluate possible effects of temperature, and to differentiate them from the effects of the refrigerant. No significant variations were observed in the analyzes of DSC, TGA, FTIR and on tensile tests for all samples, thus concluding chemical compatibility between the epoxy and the R410a refrigerant.
