摘要:
Graphene has been used in nanocomposites as constituents/doping in plastics or epoxy providing dramatic enhancement of the mechanical properties but have not progressed past the laboratory level novelty. This invention can provide a graphene based composite structure with a density less that 1.9 g/cm3 for a fiber, yarn, rope or cable and a density less that 1.5 g/cm3 for a sheet both structure have tensile and shear strength greater than either Aluminum or Steel; thus providing a graphene material that is both much lighter and stronger.

The present invention relates to a flame retardant resin composition including (A) 100 parts by weight of a blend resin composition including a styrene copolymer and a polyester elastomer, (B) 1 to 30 parts by weight of an epoxy resin, and (C) 1 to 30 parts by weight of a phosphor-based flame retardant agent. The flame retardant resin composition has improved flame retardant properties and flexibility and is used for coating a wire and a cable.

The present disclosure relates to a matting agent including emulsion polymer particles, a matting polymer composition including a matting agent, and a method of producing emulsion polymer particles. The emulsion polymer particles may be produced by a simple process using an emulsion polymerization method, and have the advantage of being relatively easy to control a degree of crosslinking. In addition, in a case where a matting polymer composition is prepared using a matting agent including the emulsion polymer particles, it is possible to manufacture a molded article having excellent appearance and matting effect without deterioration of the existing mechanical properties such as impact strength and tensile strength of a thermoplastic polymer, and in particular, an excellent matting effect may be exerted even in the extrusion processing, which has been difficult to achieve in the related art.

摘要:
Part materials for additive manufacturing applications include materials with a fluoropolymer processing aid (material-FP). These materials include one or more thermoplastic polymers and one or more fluoropolymers as a processing aid. The material-FP is used to build parts with additive manufacturing systems. Parts built using material-FP have improved physical properties including improved strength in the z-direction of the parts. Composite systems such as reinforced filaments with the material-FP also have a higher density.
