Magnesium hydroxide for flame retardants
By making full use of the crystal control technology that we had accumulated over the years, we had produced a non-halogen flame retardant for semiconductor sealing materials, which had been considered difficult to achieve magnesium hydroxide flame retardants. Our company produces it with the system of the quality control based on ISO9001.
Features
1. High filling property
ECOMAG® has a special particle shape, it can be highly filled in resin.
2. High stability
ECOMAG® has low impurities, it can be applied to Semiconductor seal materials that cannot use general magnesium hydroxide.
3. Highest flame retardance
ECOMAG® Z-10 achieves the highest flame retardance, due to its transition metal content.
4. Inexpensive
We have a lineup of ECOMAG® PZ-4 as an affordable and inexpensive flame retardant.
