Boron in polymers: A proven flame retardant
Borates in polymer and coating formulations ensure safety, maintain integrity
Polymers are everywhere—from plastics and wiring to building materials and cars. Despite clear benefits, polymers ignite and burn easily—a trait manufacturers must try to inhibit by creating an effective fire-retardant formulation.
That’s why many polymer formulations incorporate zinc borates during processing. Compared to other flame-retardant additive choices available today, borates are naturally occurring, multi-functional, and possess strong synergistic effects when used with other flame retardants.
When you’re balancing factors such as cost, quality, process stability, and safety, even a small concentration of borates can improve your formulations without disrupting sensitive production processes. Borates can help polymers exceed flammability requirement standards such as UL94 and reach the market as safe, durable products. While boron’s use as a flame retardant is the primary commercial application in polymeric materials, borates can impart valuable benefits in coatings.
