What Can Be Added to Fiberglass Resin to Improve Flame Retardancy?

When working with fiberglass products, there are times when flame retardancy is required, though clients might not specify exact standards. So, what can be added to resin to enhance flame retardancy?

For general flame retardancy without specific requirements, aluminum hydroxide is the most economical option. It is an inert filler powder that helps reduce shrinkage, increase weight, and improve flame retardancy. If weight is a concern, then using specialized flame retardants is necessary, although this option is significantly more expensive.
