Supply Silane Surface Treated Magnesium Hydroxide

Magnesium hydroxide is a new type of environmentally friendly flame-retardant agent. It decomposes upon heating to release bound water and absorbs a large amount of latent heat to reduce the surface temperature of the synthetic material it fills in the flame, inhibiting polymer decomposition and The resulting combustible gas cools down. Magnesium oxide formed by decomposition is also a good refractory material, and it can also help improve the fire resistance of synthetic materials. At the same time, the released water vapor can also be used as a smoke suppressant. Magnesium hydroxide is a well-known flame retardant, smoke suppressing, and triple-filled flame retardant in the rubber and plastics industry. Widely used in rubber, chemical, building materials, plastics and electronics, unsaturated polyester and paints, coatings and other polymer materials. Especially for the mine air duct coated cloth, PVC core conveyor belt, flame retardant aluminum plastic panel, flame retardant tarpaulin, PVC wire and cable materials, mine cable sheathing, cable accessories, flame retardant, smoke and antistatic , can replace aluminum hydroxide, with excellent flame retardant effect.

Magnesium hydroxide absorbs a large amount of heat in the combustion zone during the decomposition process, lowering the temperature of the combustion product. At the same time, the water vapor generated by the decomposition can dilute the combustible gas, and the water vapor can also isolate the contact between the silicone rubber and the oxygen, thereby playing a role in the flame retardant.

Magnesium hydroxide has a good flame retardant effect on silicone rubber. The flame-retarding effect of organosilicon-treated magnesium hydroxide is better than that of stearic acid-treated magnesium hydroxide and untreated magnesium hydroxide. The damage of silicone-treated magnesium hydroxide to the electrical insulating properties and mechanical properties of silicone rubber is lower than the other two.
