Wire and cable standard ZB is a professional grade halogen-free flame retardant enhancer produced by Taixing. It is specifically designed to solve the industry pain points of "substandard flame retardancy, high smoke emissions, and weak weather resistance" in wire and cable insulation and sheath materials. While providing excellent flame retardant and smoke suppression synergistic effects, it ensures zero negative impact or even enhancement on the volume resistivity, dielectric strength, and long-term water resistance of cable materials. This product aims at the processing characteristics and safety requirements of cable materials, realizing the four core breakthroughs of low smoke and halogen-free, efficient flame retardancy, anti-aging and easy processing. It can be compounded with magnesium hydroxide, aluminum hydroxide and phosphorus nitrogen flame retardants, and is widely used in the fields of medium and low voltage power cables, control cables, mining cables, rail transit cables, etc. It is a core special additive for global cable enterprises.
Cable oriented crystal structure+radiation resistant modification process
Using closed-loop temperature controlled hydrothermal synthesis technology, a needle shaped single crystal structure of zinc borate substrate is directionally cultivated. Needle shaped crystals can form a "fibrous barrier network" in cable materials, greatly improving the flame retardancy and mechanical strength of the material; The irradiation resistant silane grafting modification process is matched to build a UV resistant and anti-aging protective layer on the crystal surface, improve the compatibility with cable substrates such as polyethylene (PE), polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), and solve the problems such as the decline in mechanical properties of cable materials and the increase in processing difficulty caused by the agglomeration of inorganic additives. The particle size of the product is precisely controlled within 3-5 μ m, and the dispersion uniformity is 50% higher than that of general zinc borate, fully meeting the extrusion processing requirements of cable materials.
1. Melting film barrier flame retardant: During the combustion stage of cable materials, needle shaped zinc borate crystals undergo thermal decomposition, releasing boronic ester components that combine with the substrate melt to form a dense glassy flame retardant film that covers the material surface to block oxygen and heat transfer, helping cable materials easily meet UL 1581 VW-1 flame retardant standards and EN 50265 low smoke halogen-free standards.
2. Low smoke, low toxicity, and hazard reduction: Boron containing gas phase components can target and capture active free radicals such as · OH and · H in the combustion chain reaction, cutting off the path of toxic gas generation; Simultaneously suppressing the smoke release during the combustion of cable materials, the smoke density (SDR) is reduced by more than 65% compared to traditional halogen cable materials, meeting the IEC 61034 smoke density testing standard.
3. Anti aging improves service life: the radiation resistant modified layer can effectively resist the erosion of cable materials by ultraviolet rays and humid environment, and improve the outdoor weather resistance and underground corrosion resistance of cables; After addition, the anti-aging performance of the cable material has been improved by 40%, and the service life has been extended to more than 15 years, meeting the long-term service requirements in power, rail transit and other fields.
4. Processing adaptation ensures production efficiency: The product has excellent compatibility with cable substrates, does not affect the material's melt index and extrusion flowability, and can be directly adapted to existing cable extrusion production lines without adjusting processing temperature and equipment parameters, avoiding production defects such as wire breakage and surface roughness caused by the addition of additives.
1. Precise adaptation to cable standards, global compliance coverage
-Flame retardant standard: When used in combination with magnesium hydroxide for PE cable sheath material, the addition amount is only * * 8% -12% * *, which can make the material meet UL 1581 VW-1 and IEC 60332-1-2 single vertical combustion standards; When used for PVC cable materials, it can replace 30% antimony oxide and easily pass the GB/T 18380 bundle combustion test.
-Low smoke and halogen-free environmental protection: 100% halogen-free, antimony free, and heavy metal free. There is no release of corrosive and toxic gases such as hydrogen halides during combustion. It complies with the EU RoHS 2.0, REACH (224 SVHC), and EN 50265 low smoke and halogen-free cable standards, meeting the environmental access requirements of markets such as Europe, America, and Southeast Asia.
-Excellent special performance: temperature resistance level up to 105 ℃, suitable for the working temperature requirements of medium and low voltage cables; Excellent acid and alkali corrosion resistance, suitable for cable production in harsh environments such as mining and chemical industry.
2. Improve the mechanical performance of cables to ensure safe use
-The needle shaped crystal structure can enhance the tensile strength and elongation at break of cable materials. After addition, the tensile strength retention rate of PE sheath material is ≥ 92%, and the elongation at break is ≥ 350%, which meets the GB/T 2951 cable physical performance testing standard.
-Improve the anti cracking performance of cable materials, avoid sheath damage during cable laying and bending, and reduce safety hazards such as leakage and short circuit.
3. Process friendly and efficient, reducing cable production costs
-Excellent compatibility with cable substrates such as PE, PVC, XLPE, etc., evenly dispersed without agglomeration, without the need for additional dispersants, reducing the comprehensive procurement cost of additives.
-Adapting to conventional cable extrusion processes, with a wide processing temperature window (160-220 ℃), it does not affect production efficiency, while reducing waste generation and minimizing production losses for the enterprise.
-Supporting various packaging forms such as 25kg bags and 500kg ton bags, to meet the bulk procurement and small-scale trial production needs of cable enterprises.
Q1: What is the difference between wire and cable standard ZB products and general zinc borate?
A1: General zinc borate is a broad-spectrum additive that is difficult to balance the flame retardancy, smoke suppression, and mechanical properties of cable materials; This product is a cable specific formula, designed with needle like crystal structure and radiation resistant modification, which accurately adapts to cable substrates and processing technology, and can meet various cable specific standard requirements.
Q2: Can this product be used for specialized cables for rail transit such as high-speed trains and subways?
A2: Sure. The product is specially optimized for the low smoke and low toxicity requirements of rail transit cables. After being compounded with phosphorus nitrogen flame retardants, it can easily pass the EN 45545 rail transit flame retardant and toxic standards.
Q3: Is this product series suitable for the latest new energy vehicle high-voltage cable (EV Cable)?
A3: Yes. New energy vehicles with voltage platforms of 600V/800V or even higher have extremely high requirements for the corona resistance and electrical stability of cable insulation and shielding materials after high-temperature aging. Our product's low ion content and high purity are the foundation for meeting these requirements. It can serve as a core synergist in halogen-free flame-retardant sheaths or shielding materials of high-voltage cables, helping the materials pass the rigorous long-term aging and combustion tests in automotive cable standards such as ISO 6722 and LV 214.
