Blow-Out of Rubber Blocks Due to Internal Heating

Abstract

Rubber blocks undergo explosive blow-out when heated in a microwave oven. The process appears to be the same as the blow-out caused by repeatedly- applied, severe compressive loads. It is attributed to high internal pressures generated by a volatile product of thermal decomposition. Bursting took place at lower temperatures for softer compounds and for compounds that softened markedly upon heating. The blow-out temperature was also quite different for different elastomers, being low for butyl over 200 degrees C. Polybutadiene compounds did not blow-out at all, probably because the products of thermal decomposition were less volatile. (KR)
