Boron calcium stone is an unusual to calcium boron silicate minerals.
In metal or igneous rocks may have this kind of white, green, yellow, pink, purple, brown, gray, or colorless glass shiny minerals, under which the boron stone manufacturers to introduce its usage and dosage.
In using plastic, rubber formula of boron calcium stone, instead of 50% to 80% of the total zinc borate, synergistic flame retardant effect remains the same.
Reduce the cost.
Without the use of boron calcium stone in plastic, rubber formula, a single use of boric acid calcium, dosage is 30% - 40% of the total material, flame retardant effect is good.
In the fire retardant coatings, dosage of 30%
50%, the flame retardant effect is good.
Because the boron calcium stone has good covering power, can reduce other covered appropriately color pigment (
Such as titanium dioxide, etc. )
Therefore suggest when use, compound with 20% 50% of boron calcium stone, can promote its decomposition, so that the boron calcium stone plays a role of flame retardant and other organic halide compound with as soon as possible, play a better flame retardant effect.
