Why Does Phosphate Flame Retardants Exist

Why does Phosphate Flame Retardants exist? That is a problem.

Most polymer materials such as PE, PP, ABS, PU, etc are flammable. Burning emits a lot of smoke and toxic gases and makes the person poisoning suffocated and influence fire fighting and rescue work. So you need to through a certain way of making polymer with flame retardancy which triggers the Phosphate Flame Retardants market.

 

No.1 halogenated phosphate

three (2-chloroethyl) phosphate (TCEP)

1. It is the first and most widely used addition type flame retardant;

2. Can be used in soft bubbles and hard bubbles; It is better for hard foaming effect;

3. Good anti-hydrolytic and high flame retardant efficiency;

4. Easy to volatilize loss, flame retardant durability;

5. If more than 15% of the amount is used, there is a decrease in the physical properties of foam.

No.2
3(2-chloropropyl) phosphate (TCPP)

1. Additive flame retardant, with good plasticizing effect;

2. More used in PU hard foaming and PIR hard foaming, also used in PU soft foam;

3. There are two elements of phosphorus and chlorine in the molecule, and the flame retardant performance is obvious.

4. It has the functions of plasticizing, moisture-proof and anti-static.

5. However, the content of phosphorus chloride is lower than TCEP and the flame retardant effect is relatively weak.

 

No.3
Phosphate Flame Retardants

Dimethyl phosphate (DMMP)
1. A low-viscosity liquid flame retardant without halogen;

2. High phosphorus content, excellent flame retardant performance, low addition, low price, convenient use, and have double effect of reducing viscosity and flame retardant;

3. The decomposition temperature greater than 187 ℃, good thermal stability;

4. Applicable for soft and hard PU foam, especially for transparent or light-colored products and application of spray;

5. It is not suitable for pre-match in combination material, and it is recommended to be added before
foaming production.

No.4
Diethyl phosphate (DEEP)

1. Is a new type of high efficient organophosphorous flame retardant; Flame retardant efficiency is 1.5~2 times of TCPP.

2. It is widely added in the hard foam formula of various foaming systems;

3. Without halogen viscosity, it is stable in the double component system of AB material;

4. It is effective for reducing the viscosity and improving the operation of foam and polyester hard foam system.

5. Not suitable for isocyanate components such as prepolymer and single-component foam plastics.
