Let's talk about the "sweet" big brother of halogen flame retardant. Why is halogen flame retardant like sweet? Because it is just like an omnipotent "magician". Any plastic can become flame retardant under its magic. There is actually a little secret behind this, that is, halogen flame retardant relies on the "magic" of free radical termination and antimony halide isolating oxygen to achieve the flame retardant effect. This is like a powerful shield that isolates the flame from oxygen, leaving the fire source nowhere to go and naturally extinguishing.

Moreover, the choice of halogen flame retardants is also diverse, just like the desserts in a dessert shop. Many organic substances can basically be transformed into flame retardants as long as they are connected to halogen elements. Just like adding a layer of delicious chocolate sauce to an ordinary cake, it can instantly make its taste richer. Therefore, for halogen flame retardants, you only need to consider the processing performance and other later properties to easily achieve the flame retardant effect.

However, in the "sweet and salty dispute" in the plastics industry, the "salty" leader of non-halogen flame retardant seems to be a little powerless. Why do you say that? Because the mechanism of non-halogen flame retardant is very limited, just like a dish can only be cooked with fixed ingredients and methods. For example, nitrogen-phosphorus intumescent flame retardant, the amount of it added to different plastics is different, which brings great difficulties to processing. Moreover, its flame retardant mechanism relies on esterification and expansion into charcoal, just like when cooking, you need to use a specific method to make the ingredients expand. But the problem is that the addition of many fillers and additives will affect this mechanism, resulting in the flame retardant failing to play its due role.

It's like when someone accidentally adds a spoonful of salt to a carefully prepared dish, the taste of the whole dish changes. Similarly, in the formula of non-halogen flame retardant, a small change may cause the entire flame retardant effect to fail. Therefore, people who know how to process try to simplify the formula as much as possible to meet the needs of customers.

But then again, there is no absolute winner in this "sweet vs. salty battle". Although halogen flame retardant is convenient and easy to use, it also has some potential hazards, such as the impact on the environment and human health. Although non-halogen flame retardant has many restrictions and is difficult, it is more environmentally friendly and safer, and is in line with the trend of future sustainable development.

Therefore, in this "sweet and salty dispute" in the plastics industry, we should look at the pros and cons of the two flame retardant technologies more rationally. The most important thing is to choose the product that suits us.
