Everyone knows more or less about TPE, but what is the role of halogen-free flame retardant TPE materials, what does halogen-free flame retardant mean, and what is the difference between them and TPE? Like everyone, I have a lot of questions in my heart. I got the answers through the collection of various materials and the engineers who asked professional research. Today, I will share with you the common problems and answers of halogen-free flame retardant TPE.

1: What is halogen-free flame retardant? How to define halogen-free.

When you say halogen-free flame retardant, you should refer to halogen-free flame retardant materials. The so-called halogen-free, the key is that the flame retardant used in the material does not contain halogen. However, in the development of modern flame retardant industry, some completely halogen-free flame retardant systems always have one or another problem, and the flame retardant efficiency is not satisfactory. The addition of a small amount of halogen often has a synergistic effect with other flame retardant systems. In the end, what is the halogen content to be considered halogen-free? In fact, it has been stated in the regulation IEC 61249-2-21: the bromine and chlorine content are less than 900ppm respectively, and the total content of bromine and chlorine is less than 1500ppm, which is halogen-free.

Two: What are the benefits of halogen-free flame retardant plastics?

Halogen-free flame retardant is relative to halogen (such as fluorine, chlorine, bromine and other halogen elements) flame retardant materials, halogen-free flame retardant materials have many advantages, the first is the density, the density will be lower than that of ordinary halogenated flame retardants. , the common one can go to 1.6, while the halogen-free flame retardant material can be less than 1.35; the other is the tracking index (CTI), the most common halogenated flame retardant is 250 volts, and the halogen-free flame retardant CTI can be as high as 550 -600 volts; the third is the low density of smoke, the smoke produced when burning will be relatively small;

3: Analysis of technical indicators of halogen-free flame retardant cable materials.

The technical index analysis of halogen-free flame retardant cable materials is mainly analyzed from four aspects, they are: 1. Environmental protection; 2. Hardness; 3. Flame retardancy; 4. Physical and mechanical properties.
