Formulation Guidance<\/span><\/h3>\n

Achieving these specs requires careful formulation. Here are typical additives used in patented formulas for mining applications<\/span>:<\/span><\/p>\n

    \n
  • \n

    Base Resin<\/span><\/strong>:\u00a0<\/span>PVC Resin (SG-2 to SG-5 type)<\/span><\/strong>\u00a0is common, with SG-5 being frequently used<\/span>.<\/span><\/p>\n<\/li>\n

  • \n

    Anti-static Agents<\/span><\/strong>:\u00a0<\/span>Highly Conductive Carbon Black (10-40 parts)<\/span><\/strong>\u00a0is a primary agent<\/span>.\u00a0<\/span>Graphene<\/span><\/strong>\u00a0or\u00a0<\/span>Quaternary Ammonium Salts<\/span><\/strong>\u00a0are also used in newer formulas<\/span>.<\/span><\/p>\n<\/li>\n

  • \n

    Flame Retardants<\/span><\/strong>:\u00a0<\/span>Antimony Trioxide (Sb\u2082O\u2083)<\/span><\/strong>\u00a0is a classic choice, often used with\u00a0<\/span>Chlorinated Paraffins<\/span><\/strong>. Modern formulas also use\u00a0<\/span>Aluminum Hypophosphite<\/span><\/strong>,\u00a0<\/span>Brominated Paraffin<\/span><\/strong>, or\u00a0<\/span>Melamine Salts<\/span><\/strong>.<\/span><\/p>\n<\/li>\n

  • \n

    Plasticizers<\/span><\/strong>: For flexibility, use\u00a0<\/span>TOTM, DIDP<\/span><\/strong>, or\u00a0<\/span>DOP<\/span><\/strong>\u00a0(30-80 parts)<\/span>.<\/span><\/p>\n<\/li>\n

  • \n

    Other Key Additives<\/span><\/strong>:\u00a0<\/span>Calcium-Zinc Stabilizers<\/span><\/strong>\u00a0(for heat stability)<\/span>,\u00a0<\/span>Impact Modifiers<\/span><\/strong>\u00a0(e.g., CPE, MBS for toughness)<\/span>, and\u00a0<\/span>Lubricants<\/span><\/strong>\u00a0(e.g., paraffin)<\/span>.<\/span><\/p>\n<\/li>\n<\/ul>\n

    Production & Market Advice<\/span><\/h3>\n
      \n
    • \n

      Processing<\/span><\/strong>: The compound is mixed in a high-speed mixer and then melt-extruded and granulated, with temperatures typically controlled between\u00a0<\/span>130-170\u00b0C<\/span><\/strong>.<\/span><\/p>\n<\/li>\n

    • \n

      Compliance & Certification<\/span><\/strong>: For the Chinese market, obtaining the\u00a0<\/span>Coal Mine Safety Certification (“\u7164\u5b89\u8bc1”)<\/span><\/strong>\u00a0is typically mandatory for products used in coal mines<\/span>. Adhering to relevant\u00a0<\/span>industry standards<\/span><\/strong>\u00a0for cable materials is also crucial<\/span>.<\/span><\/p>\n<\/li>\n

    • \n

      Product Naming<\/span><\/strong>: Following established market conventions can be helpful. Products are often named with patterns like\u00a0<\/span>“GL-PVC-[Diameter]”<\/span><\/strong>\u00a0(e.g., GL-PVC-38, GL-PVC-50)<\/span>.<\/span><\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
