Application of boehmite
Product Overview
Aliases: Boehmite, Boehmite, Boehmite
Molecular formula: AlO(OH) or Al2O3.H2O
Among the many flame retardants, aluminum hydroxide Al(OH)3 has been widely used due to its abundant structural water, good flame retardant effect, acid resistance, flame retardant, smoke suppression, and low cost. However, ordinary aluminum hydroxide starts dehydration at 200 °C, and is completely dehydrated at 330 °C to 350 °C, while the curing of thermoplastic resin is mostly within the dehydration temperature range of aluminum hydroxide, which leads to foaming in the synthetic resin product, uneven surface, and low yield. .
The high heat resistant boehmite flame retardant produced by our company using a unique new process independently developed by our company has the following characteristics:
1. Very low content of ionic impurities
2. Advanced technological process and low production cost
3. The particle size of the product can be controlled, the median particle size can be adjusted between 1-4um, and other particle size specifications can also be customized.
4. The boehmite (AlOOH) content in the product is high, the 1% dehydration temperature is above 350 °C, the dehydration at 500 °C reaches the peak value, and EC<50uS/cm, which is a good solution to aluminum hydroxide caused by low dehydration temperature. product defects.
■Application fields:
1. Electronic substrate: improve heat resistance, improve yield, and significantly improve the flame retardant properties of materials
2. Silicone rubber, electronic potting glue: improve heat resistance, improve dielectric and thermal conductivity, and significantly improve the flame retardant properties of materials
3. Coating: Plate-like crystalline particles, prevent fluid intrusion, prevent gas permeation, improve moisture resistance, water resistance, excellent aging resistance, and significantly improve flame retardant performance
4. Rubber and plastic fillers: due to the fine plate-like crystal particles, the tensile strength, the tensile strength and the reinforcement of the tensile stress are improved, and the flame retardant performance is significantly improved
