The difference between PP halogen flame retardant and halogen free flame retardant

PP raw material is one of the five general-purpose plastics. It is easy to burn and has an oxygen index of about 18. Therefore, flame retardant modification is one of the common modification processing methods of PP. Currently, the two most common ones are halogen flame retardant PP and other is halogen-free flame retardant PP.

What is the difference between halogen flame retardant and halogen-free flame retardant PP?

1. Density, with the same flame retardant level, the density of halogen flame retardant PP is about 1.35, and the density of halogen-free flame retardant PP is about 1.04. The lower density of halogen-free flame retardant can save costs; 

2. Due to the flame retardant principle, halogen-free flame retardant PP does not produce black smoke when burned, has lower odor, is more environmentally friendly, and is not restricted by the import and export policies of developed countries;

3. Halogen-free flame retardant PP has low corrosiveness and is not easy to corrode the mold surface, and is friendly to precision molds and high-gloss molds;

4. Halogen-free flame-retardant PP dyeing has brighter colors and higher transparency, making it easier to make bright colors;

5. The electrical properties of halogen-free flame retardant PP are relatively higher;

6. In terms of price, halogen-free flame retardant PP is lower than that with halogen, and is expected to be about 560USD-845USD cheaper per ton;

7. Thermal stability, precipitation resistance and moisture absorption resistance, halogen flame retardant PP is better.

PP halogen flame retardant and halogen-free flame retardant each have their own advantages and disadvantages, and injection molding manufacturers can choose according to actual needs. However, halogen-free flame retardant has become a popular trend and is required by some policies and regulations for safety and environmental protection considerations.

Halogen-free flame retardant PP is gradually becoming a trend

Halogen-free flame retardant PP (polypropylene) is a PP material that does not contain halogen flame retardants. It achieves flame retardant effects by adding halogen-free flame retardants. Compared with traditional halogen-containing flame retardants, halogen-free flame retardant PP has better environmental protection and safety.

Traditional halogen-containing flame retardants will release halogen compounds and toxic gases during fires, causing certain harm to the environment and human health. Halogen-free flame retardants do not cause these problems, so in some special applications, such as electronic appliances, building materials, automobile parts, etc., halogen-free flame retardant PP is increasingly used.

The performance of halogen-free flame retardant PP depends on factors such as the type and amount of flame retardant. Commonly used halogen-free flame retardants include phosphates, aluminum hydroxides, etc. These flame retardants can react chemically in the PP molecular chain to form an inorganic layered structure, thereby improving the flame retardant properties of the material.

Halogen-free flame retardant PP has good mechanical properties, heat resistance and molding properties, and can be made into products of different shapes through injection molding, extrusion, blow molding and other methods. Therefore, halogen-free flame retardant PP is an excellent choice in applications that need to meet environmental protection and safety performance requirements.
