  • Publication number: 20230133560
    Abstract: Provided is a resin composition including 25 to 50 parts by weight of a phosphorus-based flame retardant composition, with respect to 100 parts by weight of a base resin including a graft copolymer containing a rubber polymer, and a styrene-based copolymer. The phosphorus-based flame retardant composition includes 30 wt % to 70 wt % of Mn+(diethylphosphinate)?n (M is a metal having an oxidation number of 2 to 5, and n is an integer selected from 2 to 5) and 30 wt % to 70 wt % of ammonium polyphosphate.

  • Publication number: 20120313297
    Abstract: A method for manufacturing a ceramic product without a sintering process, which requires no removal of binder to ensure favorable brittle fracture resistance of the ceramic product. The method includes mixing a ceramic powder with an additive and a binder to prepare a ceramic powder mixture, and treating the ceramic powder mixture through vacuum vibration pressing, to thereby form a ceramic product. The ceramic powder may include a fused ceramic powder prepared by heating the ceramic material to a melting point of the ceramic material or higher to fuse the same, cooling the fused material, and milling the cooled material.
