Flame retardant polymers are an increasingly important component of manufacturing, especially as electronic components become more prevalent in every aspect of our lives. Fires pose a hazard to safety, and flame retardant polymers are a great way to minimize the potential damage to people and property from overheating and other issues.
The function and type of flame retardant can vary based on what is needed for the product, but generally speaking these polymers work to keep fire from forming and spreading. In producing these components, polymers must meet certain requirements for ASTM, UL, and other standards.
Different resins must be handled in different ways, as their physical nature and chemical composition can vary widely. Understanding how to successfully engineer and use flame retardant polymers to create the optimal result is a challenging, but crucial part of manufacturing.
3 Types of Flame Retardant Polymers
Halogenated Flame Retardant
Largely based on bromine, the idea behind these types of materials is to deconstruct quickly so that bromine can be released and cut off the supply of oxygen to any flames.
Non-Halogenated Flame Retardant
The minerals used in these materials generate water as they decompose, which can cool heated items and quench fires.
Intumescent Chemistries Flame Retardant
Based on a process of charring, these materials decompose through an endothermic process, which produces char to separate fire from further materials to burn.
These various types of flame retardants can be implemented based on the type of protection needed, the placement of the material in the finished product, and the types of resins being used in conjunction with them.
