Surface Modified Zinc Borate

You can choose Taixing as your fire retardant manufacturer and supplier, among our products, surface modified zinc borate is a white uniform crystalline powder. During the combustion stage of the material, the modified zinc borate can quickly release crystalline water to absorb heat and cool down. The decomposed boron oxide catalyzes the formation of a dense carbon layer on the substrate, blocking the transfer of oxygen and combustible gases; During the processing stage, its surface functional groups can form chemical bonds with polymer chains, significantly improving the tensile strength, impact strength, and thermal stability of the product.

Core strengths

1. "Adaptive" interface thermodynamic compatibility design

·Principle: By grafting polymers with different chain segment lengths and polarities (such as polydimethylsiloxane, polyether, reactive polymers), the surface of the particles can accurately match the target resin (such as non-polar PP/PE or polar PA/PBT).

·Effect: In the processing of melt, the modified layer and resin molecular chains generate strong entropy driven miscibility, achieving true molecular level dispersion, fundamentally eliminating agglomeration, and forming a uniform "island structure".

2. Empowering the "multifunctional" interface

·Principle: The intelligent interface layer itself can be endowed with additional functions. For example, introducing hydrophobic segments to enhance the water resistance of composite materials; Introducing a thermal interface to construct a thermal management pathway; Introducing antibacterial functional groups to achieve integrated antibacterial and flame retardant properties.

·Effect: Transforming from a single functional flame retardant to a multifunctional performance enhancement platform, achieving "one agent multi energy".

Application field

1. High filling halogen-free flame-retardant polyolefin (automotive, home appliances)

To achieve V-0, a large amount of ATH (>60%) needs to be filled, resulting in material brittleness, high density, and poor surface quality.

2. High performance flame-retardant engineering plastics (electronic and electrical, automotive)

PA and PBT are used for connectors and coil frames, requiring high RTI, high CTI, excellent mechanical strength, and dimensional stability. Traditional flame retardants can seriously deteriorate electrical performance and toughness.

3. High reliability epoxy encapsulation material and potting adhesive

The packaging materials used for semiconductors and components require high purity, low stress, high thermal conductivity, high flame retardancy, and good adhesion with chips and lead frames.

4. Special flame retardant elastomers (wires and cables, seals)

High voltage cables and fire-resistant sealing strips for new energy vehicles require materials that are soft, flame-retardant, oil resistant, and aging resistant. Adding fillers can easily lead to loss of elasticity.

5. Coatings and adhesives

Functional additives for fire-resistant coatings and flame retardant sealants, enhancing the adhesion, corrosion resistance, and flame retardant effect between coatings and adhesive layers, suitable for steel structure fire prevention, building exterior wall insulation, and other projects.

Frequently Asked Questions

Q: Faced with so many customized models, how should I choose? What if my formula is an alloy of multiple resins?

A: The core principle of selection is compatible with continuity. For resin alloys, the type of resin that constitutes the continuous phase (matrix) should be analyzed, and the matching model should be selected. For more complex systems or uncertain situations, we provide the "Interface Spectrum Matching Analysis" service. You only need to provide resin samples or detailed specifications, and our laboratory can recommend the best model or develop customized interface solutions for you through surface energy testing and simulation.

Q: Will surface modification cover or weaken the flame retardant activity of zinc borate itself?

A: No. Our interface layer is thin, porous, and thermally stable. At the processing temperature of the polymer, it remains inert and protects the zinc borate core. When exposed to high temperatures in a fire, the interfacial layer will rapidly decompose (this process itself may also absorb heat or char), exposing the highly active surface of zinc borate, allowing its flame retardant function to be fully and even more efficiently exerted (due to excellent dispersibility). Modification is for better integration and collaboration, rather than package failure.
