Polyether TPU materials are widely used in the fields of automobiles, toys, shoes, pipes, electronic appliances, etc. However, in the fields of electronic devices and cables, the flame retardant properties of the materials are extremely high. This is because the limiting oxygen index (LOI) of conventional polyether TPU materials is only about 18%, which is much lower than the oxygen content in the air and is a flammable material. When burning, this material will not only release a large amount of harmful gases, but may also produce serious molten droplets, posing a serious threat to personal safety.

Necessity of flame retardant modification

In order to meet market demand, it is imperative to improve the flame retardant properties of polyether TPU materials. Flame retardant modification can not only effectively prevent the occurrence of fire, but also reduce the damage to people and property caused by fire. Flame retardant modified polyether TPU materials will have higher safety and reliability, and thus be more widely used in various fields.

How to achieve flame retardant modification

The key to flame retardant modification is to have a deep understanding of the degradation mechanism of different polymers and to select the corresponding flame retardant to match the polymer. Taking polyether TPU material as an example, in order to achieve efficient flame retardant effect, we need to select a flame retardant that matches its degradation mechanism. In this way, when the material encounters a fire source, the flame retardant can quickly take effect and inhibit the spread of flames and the burning speed.

Choosing the right flame retardant

The choice of flame retardant is the key. Different polymer materials have different degradation mechanisms, so it is necessary to select flame retardants that match them. For example, for materials such as polyolefins, PA, and PC, halogen-free flame retardant modification is relatively easy to achieve because their degradation mechanisms are relatively simple. However, for materials such as ABS and PS, flame retardant modification is more difficult because their degradation mechanisms are relatively complex. When selecting flame retardants, we also need to consider their impact on material properties to ensure that the flame-retardant modified materials can still maintain their original excellent properties.

Flame retardant and polymer combination

After selecting the appropriate flame retardant, we also need to study the coordination between the flame retardant and polymer materials. Different combination methods may have a significant impact on the flame retardant effect. Therefore, we need to find the best combination through experiments and theoretical analysis to achieve the best flame retardant effect.

Conclusion

Flame retardant modification is an important way to improve the safety of polyether TPU materials. By selecting appropriate flame retardants and studying the combination of flame retardants and polymer materials, we can achieve efficient flame retardant effects and enable polyether TPU materials to be used in a wider range of fields. We should also be aware of the importance of flame retardant modification, strengthen the research and application of flame retardant technology, and protect people's lives.
