A Thermomechanical (TMA) Test Method for Evaluation of Cured Polymer Encapsulating Materials.

Abstract

Thermomechanical Analysis (TMA) penetration test method was used to measure the softening point temperature of cured polymer encapsulating and coating materials. This test method was compared with the Shore Hardness Test Method by measuring softening temperature and hardness change that occurred in encapsulating materials exposed to humidities greater than 90% and temperatures above 82 C. The thermomechanical test method definitely offers a distinct advantage when evaluating the quality of a manufactured item. The TMA method is very rapid, requires a small amount of test specimen and is nondestructive to the part. (Author)
