Magnesium hydroxide for flame retardants ECOMAG®

Magnesium hydroxide Feature

Recently, the plastic products doesn't burn easily by using various flame retardants, because it is demanded that the plastic products have flame resistance.
However, because the environmental problem such as dioxin contamination gets into the news, the use of the flame retardants is being limited.
For such a background, We succeeded by developing the crystal control technology and the composite metal technology in producing the flame retardant “ECOMAG®” which is environmental compliance type.
Because the content of chlorine and the alkali metal is low, “ECOMAG®” can be applied to the electronic material usages.
We produce the composite metal hydroxide “ECOMAG®Z-10” as semiconductor seal meterials.

Magnesium hydroxide Feature and usage of grade

Grade Feature Usage  
ECOMAG® Z-10
(Composite metal hydroxide)
Special Shape
The “ECOMAG®Z-10” is special crystal shape of the polyhedrons.
So it can do uniform dispersion to the resin and does not lose resinous fluidity.
High flame retardance
This grade has high flame resistance. Because the transition metal is contained.

"Tateho's vision of creating new environment-friendly materials"

Tateho Chemical Industries Co., Ltd. was born in the town of Ako--an area blessed with a warm climate and the abundant marine resources of the Inland Sea of Japan.
The history of the salt industry in Ako is long--dating back nearly 1300 years to the Nara period.
In 1966, Tateho was established as a group of engineers seeking to provide new materials widely useful for society by putting this inherited, time-honored wisdom into full use, and by effectively utilizing bittern, a substance left after separating salt from seawater.
Since then, we have continued to provide the world with highly functional products--including magnesium oxide, magnesium hydroxide, electrofused magnesium oxide, single crystal magnesium oxide, flame retardants, and ceramics--by expanding our businesses on the basis of our proprietary crystallization control technology.
We are committed to contributing to industry worldwide under the slogan of "Aiming to be a development-oriented company friendly to the natural environment and leading the world with proprietary technologies" by continuously adhering to our environmental policy and further improving our proprietary technologies.
