Firebrake 500 is an anhydrous zinc borate that’s designed to stand up to high-temperature polymer processes. Polymer manufactures gain multiple benefits from Firebrake flame retardants—supported by technical expertise from U.S. Borax.

Recent building fires have renewed attention on fire safety in modern construction. See how borate flame retardants improve fire performance in wood products used across residential and commercial buildings.

Housing is one of the fundamental needs for people everywhere. As the world’s population grows, we need more housing with a greater variety of options. This demand presents challenges not only for the pace of building but also for building materials.

Fifty years ago, U.S. Borax introduced a multifunctional, zinc borate, flame retardant we called Firebrake. Learn how we improved the fire safety of essential materials that surround us every day.

Borate caking is a nuisance for many industrial users, but it can be prevented by paying attention to the moisture and temperature conditions in storage areas and by avoiding compaction.

Polymer producers face a range of challenges as they strive to find a balance of safety, sustainability, and quality in their products. Firebrake products offer a multifunctional solution.

Firebrake ZB provides multifunctional benefits in a wide variety of solvent-based and aqueous fire-retardant coatings, including epoxies, vinyl chlorides, acrylics, and urethanes coatings.
