To provide a pellet which is formed from a composition comprising 5 to 65 parts by mass of recycled carbon fibers as a heated product of carbon fiber reinforced resin, and 0.05 to 25 parts by mass of a nonmetal salt-based flame retardant, relative to 100 parts by mass of a polycarbonate resin having a terminal hydroxyl group content of 150 to 800 ppm.

A method of producing a flame resistant ticking includes laminating a flame resistant substrate to a decorative fabric, wherein the substrate is configured to release a chemical vapor that reduces the rate of propagation of a flame along the decorative fabric when the decorative fabric is exposed to flame. The substrate is laminated in direct contact with the inside surface of the decorative fabric. In some embodiments, the laminated ticking is configured to release less than 15 MJ of heat in the first ten minutes when exposed to a flame in accordance with the testing protocol set forth in 16 CFR 1633. Upholstered articles, such as mattresses, mattress foundations, and articles of furniture, may incorporate the flame resistant ticking layer.

A non-reinforced thermoplastic polyurethane composition having a high flexural modulus comprises 5% to 25% of a hydroxyl-functional polyol intermediate having a weight average molecular weight of 250 to 3000 and 75% to 95% hard segment comprising an unbranched, unsubstituted, straight chain diol and an aromatic isocyanate.

A functional material has, as a first component, a thermoset plastic material, as a second component, a binding material for binding the thermoset plastic material, and, as a third component, at least one additive, which is configured to improve a burning behavior, wherein the burning behavior corresponds at least to a fire reaction class C as given by DIN EN 113501-1 [German/European norm 113501-1]. A method is intended for producing such a functional material and an element is produced from such a functional material.

A fire-resistant material according to an example of the present disclosure includes a base material and at least one of a siloxane polymer and a phosphonate polymer. A method of making a fire-resistant material is also disclosed.

A 3D printing device and a method for 3D printing are provided. The 3D printing device comprises a first printing head and a second printing head. The first printing head is used to print a desired article with a first material. The second printing head is used to print support structures for supporting the desired article during printing with a second material. The method comprises the following steps: printing a desired article with a first material; printing support structures for supporting the desired article during printing with a second material; and detaching the desired article from the support structures. The first material has a first surface cooling time of the temperature drop from 170 C. to 70 C., the second material has a second surface cooling time of the temperature drop from 170 C. to 70 C., and the second surface cooling time is less than the first surface cooling time by at least 15 seconds.

This invention relates to a fireproofing article and the method of manufacturing the same. The fireproofing article comprises an external portion and an inner portion. The external portion defines external surfaces of the fireproofing article that are exposed to the environment. The inner portion is formed inside of the external portion. The external portion and the inner portion are both porous and made of a fireproofing material. The external portion has a first material density and the inner portion has a second material density. The first material density is less than the second material density. The method of manufacturing a fireproofing article comprises forming the fireproofing article with a fireproofing material through 3D printing; wherein the fireproofing article formed is porous.

A three-dimensional printing kit can include a build material, a fusing agent, and a flame retardant. The build material can include polyamide particles. The fusing agent can include a radiation absorber to generate heat from absorbed electromagnetic radiation and an aqueous liquid vehicle including water. The flame retardant can include 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide. The flame retardant can be included at from about 5 wt % to about 30 wt % in the fusing agent, at from about 5 wt % to about 30 wt % in a flame retardant agent if present that is separate from the fusing agent, or at from about 5 wt % to about 30 wt % in the fusing agent and from about 5 wt % to about 30 wt % in the flame retardant agent.

The present disclosure relates to a thermoplastic resin composition, a method of preparing the same, and a molded article manufactured using the same. The thermoplastic resin composition includes graft copolymer (A) including a polymer seed including 51 to 77 % by weight of an alkyl (meth)acrylate and 23 to 49% by weight of an aromatic vinyl compound, a rubber core surrounding the polymer seed and including 78 to 90% by weight of an alkyl acrylate and 10 to 22% by weight of an aromatic vinyl compound, and a graft shell surrounding the rubber core and including 65 to 80% by weight of an aromatic vinyl compound, 14 to 25% by weight of a vinyl cyanide compound, and 3 to 15% by weight of an alkyl acrylate; and a non-graft copolymer (B) including an alkyl (meth)acrylate, an alkyl-substituted styrene-based compound, and a vinyl cyanide compound.
