Original title: Brief discussion on the current market situation of flame retardants

Flame retardants are commonly used to prevent or reduce the possibility of combustion of combustibles. The current market situation of flame retardants is as follows.

1. Inorganic flame retardants, such as magnesium hydroxide and aluminium hydroxide, are not only inexpensive and environmentally friendly products, but also have low flame retardant efficiency and need a high amount of additives to make the materials flame retardant. Moreover, the compatibility and affinity of inorganic flame retardants are poor, which greatly reduces the impact resistance of materials, or the flexibility of materials is lost, so they are often subject to mechanical properties of materials. Used in less demanding situations.

2. Inorganic flame retardants such as antimony trioxide and zinc borate are often used as flame retardants, but their flame retardant effect is mainly reflected in assisting other halogens and other flame retardants, their own flame retardant effect is very low, or almost No.

3. Environmental friendly flame retardants abroad, many of them also have relatively high flame retardant efficiency for the corresponding materials, and can produce flame retardant materials with good mechanical properties and good appearance, but perhaps because of price and technology reasons, the current promotion in China is not very good.

Flame retardants with good properties generally meet the following requirements:

1. It has high flame retardant efficiency and can easily make the flame retardant material reach its proper flame retardant grade.

2. It has little influence on the physical properties of the materials, and the physical properties of the flame retardant materials manufactured after use should not be changed too much.

3. It has good compatibility with materials, can be uniformly dispersed in the flame retardant materials, and has good affinity; 4. The processing technology is feasible and can be used by traditional processes.

4. Affordable price, high cost performance, the cost of flame retardant materials can be accepted by the market;

5. Environmental protection, non-toxic, no harmful substances released.
