Zinc Borate Anhydrous Grade

The zinc borate anhydrous grade produced by Taixing fundamentally eliminates bound water in its crystal structure, creating excellent thermal stability and chemical inertness. Whether it is micropores in high-temperature casting resins, bubbles in powder coatings, or deterioration of electrical insulation performance, it is your ideal choice.

Core strengths

·Absolute thermal stability: Dehydration initiation temperature>380 ° C, maintaining complete inertness within the processing window of high-performance polymers such as PPS, PEEK, LCP, while traditional products have already decomposed at this temperature.

·Zero process gas release: completely eliminate the "vapor pressure" defects caused by water vaporization - internal bubbles, pinholes, and pores in the product, ensuring structural integrity and perfect surface.

·Improving electrical reliability: The presence of anhydrous molecules and related ions in the crystal structure significantly and stably increases the volume resistivity and relative tracking index (CTI) of the final composite material, which is crucial for high-voltage and miniaturized electronic devices.

·Excellent stability: Excellent resistance to hydrolysis and performance retention in humid/high-temperature aging environments, ensuring the long-term life of precision components.

High end application core

1. Conquer the Achilles' heel of high-temperature processing: moisture

During injection molding, extrusion, or powder coating curing processes at temperatures greater than 300 ° C, any form of moisture will vaporize instantly.

·Disadvantages of traditional hydrates: Local high pressure is generated inside polymer melts or uncured coatings, resulting in micro bubbles and macro pores, seriously damaging mechanical strength, dielectric strength, and appearance.

·Solution for Zinc Borate Anhydrous Grade: The absolute anhydrous characteristic eliminates the gas generation mechanism from the source, ensuring clean and dense molding and curing processes, especially suitable for thin-walled electronic connectors, laminating processes of high-performance composite materials, and automotive and aerospace components that require zero defects.

2. Expand the temperature boundary of flame retardant protection

Traditional flame retardants become ineffective after self decomposition. Anhydrous zinc borate expands the effective temperature window by about 100 ° C.

·Early intervention: At the beginning of thermal decomposition of the polymer matrix (usually>350 ° C), zinc borate anhydrous grade begins to form a viscous boric acid glass body.

·Continuous protection: During more intense fire stages, promote the formation of a more ceramic and robust expanded carbon layer, providing long-lasting insulation and oxygen barrier, which is crucial for fire-resistant components that need to maintain structural integrity.

3. Establish new standards for electrical performance

Moisture and migratory ions are the "natural enemies" of insulating materials.

·Intrinsic insulation advantage: The anhydrous crystal structure fundamentally reduces the channels and sources of ion migration.

·Improving CTI and arc resistance: Under high temperature and high humidity conditions, composite materials filled with anhydrous zinc borate can more stably maintain high CTI values and exhibit excellent arc resistance, meeting the ultimate requirements for material reliability in electric vehicles, 5G base stations, and high-voltage insulators.
