Ultrafine Zinc Borate Powder

The Ultrafine Zinc Borate Powder produced by Taixing factory is not simply ground into finer particles from traditional products, but is produced through precise hydrothermal synthesis and grading technology to produce sub micron functional powders with unique narrow distribution characteristics (D50 ≤ 1.0 μ m, D90 ≤ 3.0 μ m).Through its excellent particle size control and surface engineering, the classic synergistic function of zinc borate is perfectly combined with excellent compatibility of filling systems, providing an ideal performance enhanced flame retardant choice for demanding thin-walled products, high gloss surface applications, and high mechanical performance materials.

Core strengths

1. Ultra fine particle size+integrated modification, leading in both dispersibility and compatibility

Adopting inert gas shielded airflow crushing technology to avoid oxidation and secondary agglomeration of powder during the crushing process, combined with graded purification technology, to ensure particle size distribution uniformity (Span value) ≤ 1.2; At the same time, after crushing, the titanium acid ester stearic acid composite coating modification can be directly carried out without the need for additional dispersants, achieving molecular level dispersion in the polymer substrate, completely solving the industry pain points such as surface pitting and decreased mechanical properties caused by the addition of traditional zinc borate.

2. Surface energy engineering and high interfacial bonding strength

The product has undergone special inorganic organic composite surface treatment, and its surface energy matches the majority of polar and non-polar polymer matrices (such as PVC, EVA, PA, PP).

·Enhanced interface bonding: Optimized surface treatment promotes physical entanglement and chemical bonding between powder and resin molecular chains, effectively transferring stress and transforming traditional "weak interfaces" into enhanced interfaces.

·Inhibition of migration and precipitation: The strong interfacial bonding fundamentally prevents the migration and precipitation of flame retardants in long-term use or high temperature and high humidity environments, ensuring the long-lasting stability and surface cleanliness of product performance.

3. Enhanced surface modification and optical performance

The ultrafine particle size significantly reduces its scattering of visible light.

·Enhance surface texture: When used for high gloss or matte surface products, it can achieve a finer texture and eliminate "pockmarks" or roughness.

·Improving color matching performance: Weakening the coverage of colors, providing color designers with a wider color gamut space and higher color saturation, while reducing the use of expensive color masterbatch.

Application field

1. Thin walled electronic and electrical casing

·Challenge: The shells of smart home devices and portable electronic products are becoming increasingly thin and lightweight, requiring materials with good fluidity, impact resistance, high surface glossiness, and must meet strict flame retardant standards.

2. High performance special wires and cables

·Challenge: New energy vehicle cables and robot cables require insulation/sheath materials with multiple characteristics such as high flame retardancy, high flexibility, scratch resistance, and small outer diameter.

3. High surface quality automotive interior parts

·Challenge: Interior parts such as car dashboards and door panels not only require low VOC, low odor, and flame retardancy, but also have extremely high requirements for surface texture delicacy, tactile sensation, and scratch resistance.

4. High end coatings and sealants

·Challenge: Expanded fireproof coatings require fillers with excellent dispersibility to form stable slurries and provide uniform fire protection after curing; The sealant requires that the filler does not affect its elasticity and extrusion properties.

Frequently Asked Questions

Q: What is the core difference between ultrafine boric acid zinc powder and nano boric acid zinc powder? How should one choose?

A: This is about the choice between "industrial feasibility" and "ultimate performance". Nanomaterials pursue molecular level dispersion and quantum effects, which may bring certain performance leaps at extremely low addition amounts, but face challenges such as extremely difficult dispersion, high cost, and complex processes. Ultra fine powder is positioned as having significantly better performance than traditional fillers, while fully compatible with existing industrial equipment and processes. It solves the problems of reunion, liquidity, and cost, and is the most robust choice for large-scale production and the pursuit of high cost-effectiveness upgrades. If your goal is to directly upgrade and improve the performance of your existing production line, ultrafine powder is the preferred choice; If conducting cutting-edge material research and development without considering costs, nanomaterials can be considered.

Q: Is it easy for such fine powder to absorb moisture and agglomerate, affecting its use?

A: We solve this problem through dual protection of surface hydrophobicity treatment and special packaging. The surface of the product has been treated to reduce its surface energy, making it less likely to adsorb moisture. We use multi-layer aluminum foil bags for vacuum packaging or nitrogen protection to ensure the dryness and fluidity of the product during transportation and storage. After opening, it is recommended to use it as soon as possible and store it sealed in a dry environment.
