Dehydrated Zinc Borate

Dehydrated zinc borate is an innovative inorganic flame retardant synergist developed specifically to meet the three core requirements of modern polymer materials in high-temperature processing, low moisture sensitivity, and maintaining high performance. Dehydrated zinc borate undergoes controlled heat treatment to partially or completely remove crystal water, forming a thermodynamically more stable and reaction activity controllable "activated" state, while retaining its excellent multiple functions such as flame retardancy, smoke suppression, carbonization, and anti melting droplets, becoming a key core component of high-end halogen-free flame retardant formulations.

Core strengths

1. Excellent high-temperature processing stability

The main decomposition stage of traditional zinc borate (releasing crystal water) occurs at around 300 ℃, which overlaps with the processing window of many engineering plastics and easily leads to material degradation. The Taixing Dehydrated Zinc Borate series removes this processing interference factor through pre controlled dehydration, raising its thermal decomposition starting temperature to above 380 ℃, thereby maintaining excellent chemical inertness and physical stability during high-temperature mixing, extrusion, and injection molding processes.

2. Stable electrical and mechanical performance

The extremely low moisture content effectively prevents potential negative effects of moisture migration on the dielectric properties and mechanical strength (especially impact strength) of the polymer matrix in high humidity environments or long-term use. This provides assurance for applications in thin-walled electronic and electrical components, high-voltage connectors, and high-frequency substrates.

3. Efficient synergistic flame retardant effect

As an efficient synergist, Taixing dehydrated zinc borate has excellent synergistic effects with aluminum hydroxide, magnesium hydroxide, phosphorus nitrogen flame retardants, and ammonium polyphosphate. It can promote the formation of a denser and stronger expanded carbon layer in the condensed phase, and exert a free radical quenching effect in the gas phase, thereby reducing the amount of main flame retardant by 10% -30%, optimizing the comprehensive performance of the final product while controlling costs.

Application field
