  • High strength sheet molding composition formed with an interpenetrating polymer network
    Patent number: 11214679
    Abstract: A polyurea additive is provided that strengthens a given base sheet molding composition (SMC) An isocyanate containing species and an amine containing species are introduced into an uncured polymeric resin of a sheet molding compound (SMC) under conditions suitable for the formation of a polyurea polymer network. Upon cure of the SMC base resin, an interpenetrating network is formed that is stronger than the base SMC absent the polyurea. As a result, an article is formed from the SMC that is stronger at the same dimensions than a conventional article or thinned to achieve the same properties to obtain a lightweight article compared to that formed from conventional SMC. The properties of the article are also attractive relative to aluminum for the formation of vehicle body and exterior panels.

    Abstract: Elastomer compositions with high dielectric constants are disclosed. Embodiments of the disclosure include a high dielectric constant (high-K) elastomeric composition comprising an elastomer, carbon black (CB), and organoclay (OC). The composition is not dependent on any raw material with inherent high-k or any metal oxide type material that changes conductivity with applied voltages. The composition instead uses distributed electric fields and polarizability with carbon black and organoclays. This allows for a high-k material through polarizability with limited large-scale electron sharing.
