ProFlame MHO-3505/2/83/81 (Chemical-Method precipitation)
Product Name: Magnesium Hydroxide
Molecular Weight: 58.3
CAS No. : 1309-42-8
EINECS No.: 215-170-3
MHO series is fine Magnesium hydroxide with a high chemical purity. MHO-3505 grade is surface treated by non-polar polymer of Silane, the compatibility and combination with plastic material will be improved so that it is easy to evenly distribute into material, then the performance of fire retardant and mechanical properties is better than normal grade.

● Electronic and electrical components, conveyer belt and construction materials
● Phenol resin, fiber reinforced rubber, fine ceramics
● Petroleum additive or other chemical
Package and Storage:
Net weight: 25kg/500kg/900kg/1000kg bag
Magnesium hydroxide is sensitive to atmospheric conditions as CO2 and H2O. Opened bags must be re-closed carefully. The product has to be stored at a cool and dry place.
