Material Analysis SBS、brittleness

POE/carbon black conductivity unstable

Material Analysis POE conductivitycarbon black dispersioncritical concentrationconductive networkcarbon black structure

POE flexural modulus low

Material Analysis POEflexural modulusrigid fillernucleating agentcrystallinity

POE toughness insufficient, brittle fracture

Material Analysis POEtoughness insufficientmolecular weightcrosslinking controlcrystallization refinement

POE creep deformation large

Large creep is caused by elastomer nature; slight crosslinking and rigid filler are key
