Abstract

Abstract:

Two kinds of dispcrsants，Altfona 3050 and ALTFONA 3020 were introduced into polypropylene(PP) /carbon black(CB) composites to improve the dispersion of CB. When the contents of CB and Altfona 3050 were 8 phr and 2 phr, respectively, the composite gave a volume resistivity of 1 .08 X 10 cmwithout a loss in tensile strength. Scanning electron microscope(SEM) showed that Altfona 3050 couldpromote the dispersion of CB in a nano-scale in PP.

Key words: carbon black, polypropylene, dispersant, antistatic composite
