The choice of flame retardant depends on your application and specific flame retardant standards and regulations. There are also some other issues to consider when choosing an application. The following editor will share with you the factors that affect the selection of brominated flame retardants:
- Types and contents of bromine
In order to be effective, the selected brominated flame retardant must decompose during polymer combustion but remain stable during polymer processing; This in turn determines the type of bromine in FR. It must also have sufficient bromine content to achieve the desired flame retardant performance, while not adversely affecting physical properties and overall system costs due to high loads.
2. Thermal stability
The selected brominated flame retardant must remain stable during the mixing and injection molding process. Decomposition in these steps can lead to color formation, polymer degradation, and equipment corrosion. Therefore, choosing the right flame retardant and any necessary heat stabilizers and enhancers is crucial.
3. Aging characteristics
Your resin system may have to withstand various factors that can lead to premature performance degradation and color formation. Factors such as UV stability, thermal stability, and migration will determine the optimal flame retardant and any stabilizer needed in your system.
4. Processing characteristics
According to your processing temperature, some flame retardants can be melted and mixed, while others are used as fillers. This may affect your processing and final physical properties.
5. Standards to be achieved
The choice of flame retardant largely depends on the resin system you choose and the standards you want to meet.
6. Cost of use
It is necessary to consider the total cost of the entire packaging, which is not only a function of the cost of brominated flame retardants, but also of their required load and other additives that need to be used together to obtain a feasible system.
7. Environment
The use of brominated flame retardants can cause specific environmental restrictions. One of the key is to reduce the toxic hazards at every step of the production process, from manufacturing to final use and disposal.
8. UV stability
In many applications, flame retardant resins may have to withstand various conditions, which can lead to premature performance degradation and discoloration.
Therefore, selecting appropriate brominated flame retardants is crucial for UV stable applications, especially for outdoor use.
