Six furan resins and one epoxy resin were used in tests to determine coking values and gas evolution characteristics of the resins. The same resins, except the epoxy, were used as binders in extruded graphite rods to determine environmental factors affecting the coked density of the rods.
Coking values of the resins containing three different activators were determined by measuring residue remaining after heat treatment to 850° C. Coking values 54-56% were obtained with 8 phr to toluenesulfonic acid actiator.
Gas evolution curves were obtained by measurement of pressure rise in a constant volume apparatus during heating to 300° C at 2° C/min. Equations of the form p=AeCt were calculated for the curves.
