Flame retardant ZB-2335 is a high-end customized halogen-free flame retardant enhancer produced by Taixing, specifically designed to solve the industry pain points of "insufficient flame retardant accuracy, mechanical performance degradation, and poor processing adaptability" in materials such as engineering plastics, high-end cable materials, and special fireproof coatings. Different from the broad-spectrum adaptation shortcomings of general flame retardants, this product achieves a triple breakthrough of high thermal stability, high synergistic efficiency, and high interface compatibility. It can be used in combination with magnesium hydroxide, phosphorus nitrogen based, and expansion flame retardants, significantly improving the carbonization strength, anti drip performance, and smoke suppression effect of the flame retardant system. It is the core additive of high-end flame retardant products.
Patent customized crystal structure and modification process
By adopting the hydrothermal method for precise temperature control and crystal growth technology, a zinc borate substrate with sheet-like single crystal structure was directionally synthesized. The specific surface area increased by 45% compared to ordinary flame retardants, and the number of active sites increased by 30%, strengthening the synergistic effect of flame retardancy at the structural level; The dual functional group silane grafting modification process is used to construct an amino epoxy dual active group layer on the crystal surface, while enhancing the interfacial adhesion with polar and non-polar polymer substrates, solving the problem of narrow adaptability of single functional group modifiers, and improving the synergistic flame retardant efficiency by more than 70% compared to general modified flame retardants.
1. High thermal stability and temperature control decomposition: The decomposition temperature of flame retardant ZB-2335 can reach up to 310 ℃, far exceeding the general pentahydrate zinc borate (280 ℃). It can withstand the high temperature processing flow of engineering plastics at 220-280 ℃, and will not cause defects such as bubbles, yellowing, and mechanical property degradation in the product due to premature decomposition; Step by step dehydration and heat absorption during the combustion stage, precise control of the thermal decomposition rate of the substrate, and reduction of combustible gas generation from the source.
2. Targeted free radical quenching: 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 flame propagation path. Especially for phosphorus nitrogen based expansion flame retardant systems, it has a synergistic amplification effect, which can increase the material's oxygen index by 5-7 units and easily achieve UL94 V-0 flame retardant grade.
3. Anti dripping and anti spreading protection: During the melting and combustion stage of the material, flame retardant ZB-2335 combines with the melt to form a high viscosity glassy composite, greatly increasing the surface tension of the melt and effectively preventing the melting and dripping phenomenon of engineering plastics such as PP and ABS. It has passed the UL94 V-0 vertical combustion test without dripping, eliminating the risk of secondary fire.
1. Customized and precise collaboration, breaking through performance bottlenecks
-When used in combination with phosphorus nitrogen flame retardants for ABS household appliance casings, the addition amount only needs to be * * 6% -10% * * to achieve UL94 V-0 grade, reducing the addition amount by 30% compared to general flame retardants and significantly reducing raw material costs;

-Meets specialized and stringent standards such as ISO 6722 for the automotive industry, EN 45545 for rail transit, UL 1581 for the cable industry, and can be used in fields such as automotive interiors, high-speed rail flame retardant components, and high-end communication cables;
-The combustion residue is a stable and harmless borate zinc salt that can be recycled and reused, meeting the circular economy requirements of the EU WEEE directive, and helping enterprises achieve green production.
3. Stable weather resistance to meet long-term service requirements

Scenario 1: Global layout of automotive parts supply chain
·The same flame-retardant PP or PA6 component produced in Europe, Asia, and the United States must ensure absolute consistency in performance to meet the globally unified quality standards of the host factory.
·Solution: As a constant cornerstone of the formula, ensure that critical safety performance data such as flame retardant rating and wire ignition temperature (GWIT) of materials are highly consistent regardless of where the raw materials are purchased or produced, simplifying global material management and quality certification.
Scenario 2: Large scale manufacturing of high-end electronic appliances
·Mobile phone chargers, router cases, and other products are produced annually in the millions, and the requirement for flame retardant performance (UL94 V-0) is "zero defect". Any batch fluctuation may result in the rejection of the entire batch of products.
·Solution: Its extremely low performance variability provides an ideal foundation for statistical process control (SPC) in large-scale manufacturing. The quality control department can establish narrower and more reliable control limits to achieve true preventive quality management, rather than post inspection.
Scenario 3: Building materials products that have passed strict certification
·Applying for EU CE certification (EN 13501-1) or US UL certification requires submitting a large amount of test data and committing to continuous production consistency.
·Solution: Its predictable smoke suppression performance and flame retardant synergy make the difference between sample testing results and subsequent large-scale production results extremely small, greatly improving the first pass rate of certification and maintaining the reliability of certification, reducing certification risks and costs.
Q1: What is the core difference between flame retardant ZB-2335 and general-purpose modified zinc borate?
A1: General modified zinc borate adopts single crystal form and single functional group modification, with limited adaptability and synergistic efficiency; ZB-2335 is a directionally cultivated sheet-like single crystal, combined with bifunctional silane modification, which has higher synergistic efficiency, wider substrate adaptation range, and can accurately match the performance requirements of high-end materials.
Q2: Does it support adjusting crystal structure and particle size according to customer specific needs?
A2: Support. We have a professional crystal shape control laboratory that can customize flame retardant products with different crystal shapes (flake, needle, granular) and particle sizes (1-10 μ m) according to the customer's substrate processing technology and performance goals.
Q3: Does claiming 'predictability' mean sacrificing some extreme performance?
A3: On the contrary, predictability improves the lower performance limit by eliminating "low performance outliers" rather than lowering the upper limit. A product with large fluctuations may have high optimal performance, but its worst performance may not meet the standards. ZB-2335 ensures stable performance output within the "excellent" range through precise control, eliminating the risk of failure. In industrial production, stable excellence is far more valuable than occasional excellence.
