All-Round Performance Zinc Borate

All-Round Performance Zinc Borate is a high-end and versatile flame retardant and efficiency enhancing additive produced by Taixing, specifically designed to solve the industry pain point of traditional zinc borate, which is characterized by single performance and neglecting one aspect. This product achieves a quadruple balance breakthrough in flame retardant efficiency, smoke suppression effect, substrate mechanical properties, and weather stability. It can be compounded with various flame retardants such as magnesium hydroxide, phosphorus nitrogen series, and expansion type, and is widely suitable for a full range of materials including general plastics, engineering plastics, high-end cable materials, and special fireproof coatings.

Flame retardant mechanism

Using gradient temperature controlled hydrothermal synthesis technology, the three crystal forms of zinc borate, namely sheet, needle, and granular, are precisely compounded in proportion to construct a three-dimensional synergistic structure of "barrier heat absorption free radical capture"; The supporting amino epoxy methyl tri functional group organic silicon grafting modification process forms an active layer on the crystal surface that matches different polar substrates, while strengthening interfacial bonding and weather resistance, solving the problem of performance shortcomings in single crystal form and single functional group modified products. The particle size of the product is precisely controlled within 3-6 μ m, with a specific surface area that is 50% higher than that of ordinary zinc borate, and a synergistic flame retardant efficiency that is over 65% higher than that of the universal modified version.

mechanism of action

1. Efficient flame retardant and anti spreading: The composite crystal structure dehydrates and absorbs heat step by step during the combustion stage, and can absorb 420J of heat per gram of product, rapidly reducing the surface temperature of the substrate; At the same time, the released boronic ester groups crosslink with the substrate to form a high-strength and dense ceramicized carbon layer, which blocks the bidirectional transfer of oxygen and heat, and easily helps the material achieve UL94 V-0 and GB 8624-2022 B1 flame retardant standards.

2. Low smoke, low toxicity, and hazard suppression: 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; The carbon layer structure synchronously adsorbs smoke particles, reducing the material's smoke density (SDR) by more than 60% compared to traditional halogen systems, and the release of toxic gases meets the GB/T 20285-2006 standard.

3. Interface compatibility protection: The multifunctional modified layer forms physical entanglement and chemical cross-linking with the molecular chains of the polymer substrate, filling the interface gaps between inorganic additives and organic substrates to avoid material brittleness; The tensile strength retention rate of the added product is ≥ 95%, and the impact toughness retention rate is ≥ 93%, fully meeting the structural performance requirements of high-end products.

4. Weather resistance, stability and anti-aging: the silicone modified layer forms a hydrophobic protective film on the surface of the substrate, improving the product's ability to resist ultraviolet rays, moisture and chemical corrosion; The product has been used in a wide temperature environment of -50 ℃~180 ℃ for more than 2 years, with a flame retardant and smoke suppression performance attenuation rate of ≤ 5%, and no precipitation or migration phenomenon.

Core strengths

1. Four in one, with no shortcomings in performance

-Flame retardant and efficient: The recommended addition amount is only 5% -10%. When used in combination with phosphorus nitrogen based ABS materials, the oxygen index increases to over 34%, reaching UL94 V-0 level, and the addition amount is reduced by 30% compared to general zinc borate;

-Significant smoke suppression: The smoke density level (SDR) is reduced by 60% -65%, and there is no release of toxic gases such as hydrogen halides during combustion, meeting strict smoke and toxic standards such as EN 45545 for rail transit and ISO 6722 for automotive interiors;

-Mechanical protection: There is no significant negative impact on the mechanical properties of substrates such as PP, PE, ABS, PVC, etc. The impact strength retention rate of hard products is ≥ 93%, and the flexibility retention rate of soft products is ≥ 90%;

-Weather resistant and stable: Excellent performance in UV resistance, moisture resistance, and high and low temperature resistance. Outdoor products have no significant performance degradation after more than 2 years of use, and are suitable for long-term service scenarios such as outdoor building materials and automotive exteriors.

2. Zero halogen environmental protection

-100% halogen-free, antimony free, and heavy metal free. The combustion residue is stable and harmless zinc borate salt, which can be recycled and reused, meeting the circular economy requirements of the EU WEEE directive;

-Meet the basic compliance requirements for food contact grade materials, and can customize specialized formulas that comply with the US FDA 21 CFR 177.1520 standard, suitable for tableware, food packaging, and other fields.

3. High cost-effectiveness, outstanding advantages in cost reduction and efficiency improvement

-The single product achieves the four functions of flame retardancy, smoke suppression, mechanical protection, weather resistance and stability, without additional smoke suppressants and anti-aging agents, which can reduce the comprehensive purchasing cost of additives by 15% -20%;

-The low additive content reduces the impact of additives on the properties of the substrate, while lowering the transportation and storage costs of raw materials, helping enterprises improve product profit margins

Frequently Asked Questions

Q1: What is the difference between comprehensive performance zinc borate and ordinary modified zinc borate?

A1: Ordinary modified zinc borate is mostly modified with a single crystal form and functional group, focusing only on one performance; This product adopts polycrystalline composite+three functional group modification technology to achieve four functions of flame retardancy, smoke suppression, mechanical protection, and weather stability, and is suitable for a wider range of scenarios.

Q2: Does "all-around performance" mean being "world number one" in every single item?

A2: No, it means that within the set high-end application target framework, all key performance has reached the level of "excellent" or "superior", and there are no shortcomings. Its design goal is to become the "all-around champion" with the highest overall score, rather than a "world record holder" in any individual event. For example, its smoke suppression efficiency may be slightly lower than top-level specialized smoke suppressants, but it provides top-level smoke suppression while also retaining top-level flame retardancy and mechanical properties, which cannot be compared to any single function product. It solves systemic problems.

Q3: In terms of sustainability, what impact does this integrated design have on the recycling and reuse of materials?

A3: Integrated design is actually beneficial for sustainability. Firstly, the introduction of a single component simplifies the difficulty of separation and identification during recycling. Secondly, its strong interface binding in physical recycling helps to maintain the mechanical properties of the recycled material. More importantly, we are committed to making its chemical composition compatible with mainstream chemical recycling processes such as depolymerization and cracking, avoiding the introduction of toxic elements that are difficult to remove or stubborn structures that hinder depolymerization. Full functional integration is an important step towards materials designed for the circular economy.
