Study of electric conductive polysulfide sealant

Along with the rapid development of electronic industry,the requirements of electronic equipment to electromagnetic environment become more and more rigorous.Electric conductive polysulfide sealant is needed for sealing the electronic equipment.We studied the effect of conductive carbon black on the electric and mechanical properties of polysulfide sealant,and obtained the optimal dosage of conductive carbon black in sealant.Furthermore,we also investigated the influence of high temperature air aging on the conductive polysulfide sealant.The results showed that the conductive polysulfide sealant can be used in high temperature environment.
