In recent years, silicone rubber flame retardant technology has gradually become the focus of attention and research. Although silicone rubber is non-toxic and tasteless, high and low temperature resistance, weather resistance, good electrical insulation performance, but itself flammable, so the need for flame retardant modification, in order to expand its application in electronic and electrical, mechanical, chemical and other industries.

Early flame retardants used for silicone rubber are mainly flame retardants containing halogens, while improving the flame retardancy of silicone rubber, the irritating gas containing chlorine or bromine will be released during the combustion process, which is harmful to the environment and the human body, and is gradually eliminated. Aluminum hydroxide is an environmentally friendly flame retardant, filled in rubber, plastic, will inhibit its temperature rise in a high temperature environment, flame retardant at the same time does not produce toxic gases, but also improve the anti-arc and anti-leakage performance of the substrate. Aluminum hydroxide is widely used in water and thermal environment with stable performance, non-volatilization, strong color retention and low price.

Application characteristics: Adding aluminum hydroxide to silicone rubber can play a good flame retardant effect. With the increase of the amount of aluminum hydroxide, the flame retardant property of silicone rubber is significantly improved, the vulcanized rubber's Shore A hardness, 300% constant elongation stress and tensile permanent deformation are gradually increased, the tensile strength, elongation at break and tear strength are gradually reduced, the electrical insulation performance is decreased, but it can still meet the material performance requirements.

Highly recommended: Aluminum hydroxide powder H-42

H-42 is a hexagonal single crystal, which makes their surface parallel arrangement is very strong, coupled with its high whiteness characteristics, so when used in products, it has a very smooth surface and high whiteness characteristics.

Product features:

1, Bayer synthesis, high purity

2, the particle size is small, and the particle size distribution is narrow, the average particle size is only 1 micron

3, the finished product appearance is very smooth and delicate

4, low smoke halogen-free flame retardant, in line with green environmental protection concept

5, for different products have different surface treatment, improve product compatibility
