Abstract: A self-heating sealant or adhesive may be formed using multi-compartment microcapsules dispersed within a sealant or adhesive. The multi-compartment microcapsules produce heat when subjected to a stimulus (e.g., a compressive force, a magnetic field, or combinations thereof). In some embodiments, the multi-compartment microcapsules have first and second compartments separated by an isolating structure adapted to rupture in response to the stimulus, wherein the first and second compartments contain reactants that come in contact and react to produce heat when the isolating structure ruptures. In some embodiments, the multi-compartment microcapsules are shell-in-shell microcapsules each having an inner shell contained within an outer shell, wherein the inner shell defines the isolating structure and the outer shell does not allow the heat-generating chemistry to escape the microcapsule upon rupture of the inner shell.

Abstract: Materials including support layers and fiber-free compositions are disclosed, as well as related articles and methods for making the materials. The fiber-free compositions are formed from a precursor composition that includes a nitrile butadiene rubber, a nanoclay and a cure package including a sulfur-based curing agent. The fiber-free compositions may have a substantially reduced weight and compressive modulus in comparison to conventional rubber. Thus, the fiber-free compositions may provide improved ballistic properties in addition to reduced density and thickness. Precursor compositions for forming the insulative composition may have good flow characteristics. The fiber-free compositions may be used in a variety of applications, such as personnel body armor, ground vehicle armor and aircraft armor systems.

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.
