    Abstract: A filler includes a first precursor and a second precursor; the first precursor is a hollow filler with a surface covered by a first silane coupling agent; the second precursor is a non-hollow filler with a surface covered by a second silane coupling agent; the first precursor and the second precursor are connected by a covalent bond formed by a chemical reaction between the first silane coupling agent and the second silane coupling agent. Also included are a preparation method of the filler and a resin composition containing the filler. A prepreg, a resin film, a laminate, or a printed circuit board made from the resin composition has excellent thermal resistance after moisture absorption, low Df variation rate under moisture and heat, low water absorption rate, high copper foil peeling strength, the prepreg having a smooth appearance and even color, and absence of branch-like pattern on laminate.

    Abstract: A water pipe for mining operations has an outer diameter of 20 to 200 millimeters and a wall thickness of 2 to 20 millimeters. The water pipe includes a composition containing 58 to 82 parts by weight poly(phenylene ether), 8 to 18 parts by weight of a hydrogenated block copolymer of an alkenyl aromatic monomer and a conjugated diene, 0 to 15 parts by weight of polystyrene selected from the group consisting of homopolystyrenes, rubber-modified polystyrenes, and combinations thereof, and 10 to 20 parts by weight of a flame retardant comprising an organophosphate ester, wherein parts by weight values are based on 100 parts by weight total of the poly(phenylene ether), the hydrogenated block copolymer, the polystyrene, and the flame retardant. The water pipe exhibits a desirable balance of impact strength, tensile strength, burst pressure resistance, static pressure resistance, and flame retardancy.
