ELECTRICALLY CONDUCTIVE THERMOPLASTICS ELASTOMER COMPOSITION COMPRISING OF CARBON NANO TUBE

摘要

PURPOSE: A conductive thermoplastic elastomer composition is provided to have excellent electric conductivity and to have excellent mechanical properties and restoration at room temperature and high temperatures while maintaining the surface hardness of 50 (shores A). CONSTITUTION: A conductive thermoplastic elastomer composition comprises 30-50 wt% of a terpolymer; 30-45 wt% of a paraffin oil; 5-10 wt% of a polyolefin-based resin; 5-20 wt% of an inorganic additive; and 3-15 wt% of a polyphenylene ether-based resin; and additionally includes 1.5-4.0 parts by weight of carbon nanotubes as a conductive filler based on 100 parts by weight of the thermoplastic rubber composition. The weight average molecular weight of the terpolymer is 140,000-180,000.
