A thermally conductive polyamide compound is disclosed. The compound comprises a polyamide matrix, boron nitride, and a laser direct structuring additive dispersed in the matrix. The compound can be extruded, molded, calendered, thermoformed, or 3D-printed into a heat dissipating and laser direct structured article.


Aliphatic polyimides are synthesized by a reaction of 2 moles of an unsaturated monoanhydride or an unsaturated diacid with both one mole of a diamine and one mole of a monoamine. Imidization of intermediates so formed from those reactions resolve to 6 possible bicyclic imidic structures bridged by monoamidic or saturated hydrocarbon spans, more likely the latter. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.


Aliphatic polyimides are synthesized by a 1:1 molar ratio reaction of an unsaturated monoanhydride or an unsaturated diacid with a diamine. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.


Aliphatic polyimides are synthesized by a 2:1 molar ratio reaction of an unsaturated monoanhydride or an unsaturated diacid with a diamine. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.

Plastisol compositions having a two-resin interpenetrating polymer network (IPN) are disclosed. The compositions begin with blocked isocyanate grafted acrylic polymer, blocked isocyanate urethane prepolymer, plasticizer, optionally pigment, and optionally thixotropic agent. When subjected to a thermal cure, the isocyanate groups on the acrylic polymer and urethane prepolymer both become unblocked and both react with the crosslinking agent to form an interpenetrating acrylic-polyurethane network. The two-resin IPN offers improved storage stability, hand-feel characteristics, and processing properties for textile printing among other uses. Preferably these plastisol compositions are essentially free of polyvinyl halides and phthalates restricted for regulatory reasons.

A thermoplastic elastomer compound includes styrenic block copolymer and high softening point tackifier. The styrenic block copolymer has a Copolymer Tan Delta Peak Temperature and the thermoplastic elastomer compound has a Compound Tan Delta Peak Temperature. The Compound Tan Delta Peak Temperature is greater than the Copolymer Tan Delta Peak Temperature. The thermoplastic elastomer compound exhibits useful damping properties at or above room temperature while also advantageously possessing improved stability for processing and/or applications at high temperatures and upon exposure to weathering.

Significant disadvantages of the use of polylactic acid (PLA), lack of good heat stability and flame retardance, have been overcome by the use of an aryl phosphate in combination with talc. The compound achieves a threshold of 65 C. in heat deflection temperature and V-0 flame retardance at 1.6 mm thickness.


A thermoplastic elastomer compound is disclosed having a high strain recovery rate and a high strain fixity rate to provide shape memory, preferably manageable shape memory. One type of thermoplastic elastomer compound is comprises a maleated styrenic block copolymer and polycaprolactone to achieve the shape memory. A second type of thermoplastic elastomer compound comprises styrene-ethylene/butylene-styrene and a paraffin wax having less than about 0.5% oil content. Shape modes of articles made from the thermoplastic elastomer compound can be altered by at least one thermo-mechanical event to cause deformation of the compound from a first shape to a second shape with retention of the compound in the second shape for any reasonable time interval.
