Magnesium hydroxide is an inorganic flame retardant, which has the following advantages:
Non -toxic, tasteless, non -corrosive
Without halogen, there will be no toxic smoke
Have good flame retardant and smoke
Low price and rich source
The application requirements of magnesium hydroxide flame retardant are as follows:
Granularity: The smaller the particle size of the flame -retardant of magnesium hydroxide, the better the flame retardant effect. Generally speaking, the particle size of magnesium hydroxide flame retardant should be less than 2 μm.
Disable: Magnesium hydroxide flame retardant should be evenly scattered in polymer materials, otherwise it will affect the performance of the material.
Compatible: Magnesium hydroxide flame retardant should be compatible with polymer materials, otherwise the mechanical properties of materials will be reduced.
Magnesium hydroxide flame retardant can be used for the following materials:
Plastic: polyolefin, polystyrene, polyvinyl chloride, polyurethane, etc.
Rubber: Natural rubber, synthetic rubber, etc.
Wood: wood, paper, etc.
Textiles: cotton, hemp, polyester, etc.
Coatings: paint, coating, etc.
The specific application of magnesium hydroxide flame retardant is as follows:
Plastic: magnesium hydroxide flame retardant can be used for flame retardant of plastics such as polyolefins, polystyrene, polyvinyl chloride, polyurethane. For example, adding 15%~ 20%magnesium hydroxide flame retardant to polypropylene can increase its oxygen index to more than 26%.
Rubber: Magnesium hydroxide flame retardant can be used for flame retardant such as natural rubber and synthetic rubber. For example, adding 10%to 15%of magnesium hydroxide flame retardants to natural rubber can reduce its combustion rate by more than 50%.
Wood: Magnesium hydroxide flame retardant can be used for flame retardant for wood, paper, etc. For example, soaking wood in a solution containing magnesium hydroxide flame retardants can extend the burning time by more than 3 times.
Textiles: Magnesium hydroxide flame retardants can be used for flame retardant of textiles such as cotton, hemp, and polyester. For example, soaking cotton fabrics in a solution containing magnesium hydroxide flame retardants can reduce its combustion rate by more than 70%.
Coatings: Magnesium hydroxide flame retardant can be used for flame retardant in paint, coatings, etc. For example, adding 10%to 15%of magnesium hydroxide flame retardants to the paint can extend the burning time by more than double.
