Sunua's national invention patent for non-crosslinked antitracking polyolefin sheath material for optical cables and its preparation method

Recently, Hebei Sunua Advanced Material Co., Ltd. of "non-crosslinked antitracking polyolefin sheath material for optoelectronic cables and its preparation method" was pleased to obtain national invention patent authorization for our company's innovative work to add another fruit!

The invention patent of "non-crosslinking electric trace-resistant polyolefin sheath material for optical cable and its preparation method" involves the technical field of polymer composite materials, and provides non-crosslinking electric trace-resistant polyolefin sheath material for optical cable with ethylene-propylene copolymer, high-density polyethylene and metallocene-catalyzed low-density polyethylene as the base resin material and the addition of metalocene-catalyzed low-density polyethylene as the base resin material, and the addition of metalocene-catalyzed low-density polyethylene as the base resin material. As the base resin material, and add low temperature ceramic glaze powder, metal oxides, zinc borate and fluorine-modified organosilanes together as the sheath material of the trace resistance performance to enhance and improve the functional additives, so that the resulting sheath material at the same time has excellent electrical insulation properties, high trace resistance grade and good hydrophobicity, 20 ℃ volume resistivity are in the 3.00 × 1014Ω -m or more, trace resistance grade up to 1A3.5 or 1A4.5, hydrophobicity grade as low as HC2, broadening the application areas of the existing sheathing materials.

The "non-crosslinked trace-resistant polyolefin sheathing material for optoelectronic cables and its preparation method" invention patent provides a cost-effective sheathing material preparation method is simple to operate, and can realize the large-scale production.
