  • Patent number: 10455886
    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.

    Abstract: Electrically conductive vulcanised epoxidised 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 vulcanisation system, either sulfur or peroxide type does not affect the electrical properties of the vulcanised 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 vulcanised 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 colour level of all these vulcanised 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.

  • Publication number: 20170009029
    Abstract: Epoxidised natural rubber [ENR] based vulcanised-blends with two different types of electrical conductive filler (i.e. conductive grade-carbon black and intrinsically electrical conductive polymer) may be produced respectively by using either internal mechanical mixing method or open milling method or the combination of the two methods. All these ENR based vulcanised-blends show high consistent reversible electrical behaviour under the tensile straining process. They also exhibit useful mechanical properties with tensile strengths up to 28.0 MPa, elongations at break up to 800.0% and Dunlop rebound resiliencies up to 55.0%. The lower the rebound resilience, the better the damping property and shock absorption ability for the ENR based vulcanised-blends. As a result, these ENR based vulcanised-blends are ideal to be used for manufacturing flexible sensors that may correspond to the tensile straining process.
