A hardener composition can be used for a reactive resin system containing a reactive resin based on radically curable, ethylenically unsaturated compounds. The hardener composition contains a hardener for the reactive resin and a filler mixture. The filler mixture is composed of a first filler having a first average particle size d.sub.50,1 and a second filler having a second average particle size d.sub.50,2. The first average particle size d.sub.50,1 of the first filler is greater than the second average particle size d.sub.50,2 of the second filler (d.sub.50,1>d.sub.50,2). The ratio d.sub.50,1 to d.sub.50,2 (d.sub.50,1:d.sub.50,2) is in the range of 8:1 to 100:1. The filler mixture is useful, and a reaction resin system can contain the hardener composition.

Electrically conductive thermoplastic polymer composites of particulate thermoplastic polyester polymers, electrically conductive components (carbon nanofibers, graphene nanoplatelets, and/or conductive metal nanoparticulates), processing aids such as plasticizers, thermal stabilizers, etc., as well as nanoscopic particulate fillers such as nanoscopic titanium dioxide, etc., the electrically conductive components being distributed substantially uniformly in the composite to form an electrically conductive network. Also, methods for preparing thermoplastic polymer composites, a system for collecting extruded filaments prepared from thermoplastic polymer composites as a coil of filament, as well as method for tempering articles formed from thermoplastic polymer composites to increase the degree of crystallinity of the thermoplastic polymers and thus their mechanical strength properties.

Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. The first particulate mix includes greater than 50 weight percent of first metallic particles.

A reinforcing clinical wrap is provided with integral thermal management. The clinical wrap includes a fluid circuit for a heat transfer medium to circulate between a fluid inlet and a fluid outlet. A shape conforming medium is disposed within a portion of the clinical wrap providing selective reinforcement support of the portion of the clinical wrap to conform to a surface of a patient. Non-limiting examples of the shape conforming medium may include a magnetorheological elastomer, a magnetorheological elastomer, a magnetorheological foam, a UV curable resin, and a phase change material.

A curable casting compound, including a polymeric binder and at least one particulate filler incorporated therein, wherein the filler is ground fruit kernels and/or fruit shells, wherein either only the at least one filler composed of ground fruit kernels and/or fruit shells or additionally at least one further particulate inorganic filler is present.
