Abstract:
Electrically conductive vulcanized epoxidized natural rubber [ENR]-carbon black blends can be produced by using either internal mechanical mixing method or open milling method. These two methods are commercially friendly due to their practicability and high production rate. The addition of vulcanization system, either sulfur or peroxide type does not affect the electrical properties of the vulcanized blends. All vulcanized blends prepared in this innovation show useful electrical properties with electrical volume resistances as low as the order of 101 ohms. All these vulcanized blends also exhibit good mechanical properties with tensile strengths up to 26.0 MPa and Dunlop rebound resiliencies of 14.0% (i.e. high damping property). The black color level of all these vulcanized blends is adjustable. As a result of good electrical and mechanical properties (especially high damping property), they have good potential to be used for antistatic footwear manufacturing and application.
