Dow Chemical tells everyone the role of wood flame retardants.

1: High flame retardancy, which can prevent flame combustion and smoldering (flameless combustion, red hot combustion);

2: The flame retardant itself is non-toxic and does not pollute the environment during production and use. The pyrolysis products of flame retardant wood should be less smoke, low toxicity, non-irritating and non-corrosive;

3: Durable flame retardant performance, no thermal and photolysis occurs during use, and it is not easy to hydrolyze and lose;

4: low moisture absorption, good dimensional stability of flame retardant wood;

5: The physical and mechanical properties and process properties of wood are basically unaffected;

6: Anti-corrosion and insect-proof performance;

7: The environmental characteristics of wood such as vision, touch and regulation are basically unaffected;

8: Low cost, rich sources, easy to use.

Wood is a porous complex natural organic substance mainly composed of cellulose, hemicellulose and lignin. Its characteristics are: under normal processing and use conditions, it does not dissolve and does not melt, so the processing method is different from synthetic polymers; wood molecules contain a large number of hydroxyl-containing polar groups such as hydroxyl groups and methylol groups, so they are highly hygroscopic. Poor dimensional stability; in addition to flammable, it has the characteristics of easy decay and easy chemical degradation. The above-mentioned characteristics of wood determine that the mainstream varieties of wood flame retardants are all water-based products, and the main method of addition is the infusion method.

Dole Chemical is a high-tech enterprise integrating R & D, production and sales of fine chemicals. The company has undergone considerable development in more than ten years. It is distributed throughout the country and serves more than 4,000 customers. It also cooperates with major universities in China to develop new products and introduces a large number of foreign advanced technology patents and equipment. In the halogen-free flame retardant industry, we are a leading developer, manufacturer and marketer, providing customized flame retardant application services to many well-known companies.
