This invention provides resin formulations which may be used for 3D printing and pyrolyzing to produce a ceramic matrix composite. The resin formulations contain a solid-phase filler, to provide high thermal stability and mechanical strength (e.g., fracture toughness) in the final ceramic material. The invention provides direct, free-form 3D printing of a preceramic polymer loaded with a solid-phase filler, followed by converting the preceramic polymer to a 3D-printed ceramic matrix composite with potentially complex 3D shapes or in the form of large parts. Other variations provide active solid-phase functional additives as solid-phase fillers, to perform or enhance at least one chemical, physical, mechanical, or electrical function within the ceramic structure as it is being formed as well as in the final structure. Solid-phase functional additives actively improve the final ceramic structure through one or more changes actively induced by the additives during pyrolysis or other thermal treatment.

The present invention relates to a thermoplastic resin composition for laser direct structuring, containing: a polycarbonate resin; an inorganic compound comprising titanium dioxide and zinc sulfide; a fibrous inorganic filler; and an additive for laser direct structuring. Therefore, the present invention can provide: a thermoplastic resin composition for laser direct structuring, capable of implementing excellent whiteness while maintaining excellent impact resistance and rigidity; and a molded article comprising the same.

A versatile silicone resin reflective substrate which exhibits high reflectance of high luminance light from an LED light source over a wide wavelength from short wavelengths of approximately 340-500 nm, which include wavelengths from 380-400 nm near lower limit of the visible region, to longer wavelength in the infra-red region. The silicone resin reflective substrate has a reflective layer which contains a white inorganic filler powder dispersed in a three-dimensional cross linked silicone resin, the inorganic filler powder having a high reflective index than the silicone resin. The reflective layer is formed on a support body as a film, a solid, or a sheet. The silicone resin reflective substrate can be easily formed as a wiring substrate, a packaging case or the like, and can be manufactured at low cost and a high rate of production.

A thermoformed storm water chamber has an exterior surface formed of first layer having an increased reflectance additive and an interior surface formed of a second layer. The increased reflectance additive is a pigment (other than a black pigment) or may be a mineral component. Optionally, a supplemental ultraviolet and/or antioxidant protection additive is also provided in the first layer. The thickness of the first layer is less than the thickness of the second layer, optionally in a 20%/80% of total thickness ratio. The two layers may be made from the same or different HDPE or blends thereof.

A resin product including an antireflection surface includes a plurality of first concave portions, a plurality of second concave portions, and a component surface. The first concave portions have opening widths equal to or larger than 1 m and equal to or smaller than 300 m. The second concave portions are formed on each of the plurality of first concave portions and have opening widths equal to or larger than 10 nm and equal to or smaller than 1 m. The component surface is configured to surround each of the plurality of first concave portions.
