This disclosure describes compositions, kits, methods, systems, and three-dimensional parts. According to an example, described herein is a method of forming a polymeric powder build material composition for three-dimensional printing, the method comprising mixing a thermoplastic polymer powder composition, antioxidants, flow aids, a surface modifying agent, antistatic agents, and filler.

Cables are constructed with extruded discontinuities in the cable jacket that allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of material in the cable jacket.

The invention includes a method of providing an intermediary layer in a laminated structure, between two adjacent layers, where the intermediary layer contains a fiber having an extrusion coating. The intermediary layer may form a textile constructed from the fibers, the intermediary layer, when the lamination method proceeds, provides the adhesion between the adjacent layers, as well as reinforcement for the laminated structure.

Provided herein are polyamide compositions having desirable flow properties, for example low viscosity, which is useful for molding small components. The polyamide compositions comprise a polyamide comprising 1,10-decanediamine terephthalamide (10T) repeating units; a copolyamide comprising repeating units derived from terephthalic acid and from a diamine containing 6 or fewer carbon atoms; a reinforcing agent; and optionally, one or more of a flame retardant, a flame retardant synergist, and a lubricant.

An optical fiber cable includes: a core including optical fibers; a reinforcing wrap that surrounds the core; and a sheath that accommodates the core and the reinforcing wrap. The reinforcing wrap includes an overlapping portion. A first end portion of the reinforcing wrap overlaps a second end portion of the reinforcing wrap at a portion of the reinforcing wrap in a circumferential direction of the optical fiber cable in a cross-sectional view.

Disclosed is a flame-retardant HIPS material and a preparation method thereof, comprising the following components: 90 parts to 67 parts of a HIPS resin; 8 parts to 15 parts of a brominated flame retardant; and 3 parts to 7 parts of an auxiliary flame retardant; wherein the auxiliary flame retardant is a 1,3,5-triazine compound. In the present invention, a synergistic compounding of the brominated flame retardant and the auxiliary flame retardant effectively reduces an amount of the brominated flame retardant, and a stable UL 94 (1.5 mm) V-0 flame-retardant class can be achieved. Compared with the existing brominated flame-retardant HIPS, the present invention has a low halogen content, low gas, and high cost performance ratio, which avoids excessive acid gas from forming air lines on the surface of parts, has a good appearance.

A fusible, phase-change powder composition includes a plurality of powder particles comprising a polymer composition, an unencapsulated phase-change material, and optionally, an additive composition; wherein the powder composition is fusible at a temperature of 25 to 105° C., or 28 to 60° C., or 45 to 85° C., or 60 to 80° C., or 80 to 100° C.

Disclose are is method of manufacturing a ventilation sheet for a vehicle. The ventilation sheet for a vehicle is manufactured by performing anti-fouling finishing treatment using an anti-fouling coating agent including an anti-fouling composition. The anti-fouling properties can be improved to prevent the sheet from being fouled, and flame-retardant treatment is performed through a flame-retardant aqueous solution including flame-retardant PET fiber and flame retardant in bath so that the deterioration of flame retardancy caused by the improved anti-fouling properties can be prevented through the flame-retardant treatment while ventilation properties are maintained.

A flame retardant composition includes poly(carbonate-bisphenol phthalate ester) or a combination of poly(carbonate-bisphenol phthalate ester) and a poly(ester), an organophosphorous flame retardant present in an amount effective to provide 0.5-0.8 wt % of added phosphorous; 5-45 wt % of glass fibers; optionally, a poly(carbonate-siloxane); optionally, 0.01-10 wt % of a flame retardant sulfonate salt; optionally, 0.1-0.6 wt % of an anti-drip agent; and optionally, 0.01-10 wt % an additive composition, wherein the amount of the polymer component, the organophosphorous flame retardant, the glass fibers, and the optional components total 100 wt %; and wherein a molded sample of the flame retardant composition has a UL 94 rating of V0 at a thickness of 1.2 millimeter, preferably a CA UL 94 rating of V0 at a thickness 0.8 millimeter.
