AMMONIUM METAPHOSPHATE Resistant O-Rings and Seals

Ammonium Metaphosphate is also known as Ammonium Polyphosphate and is often used as a flame retardant. It is found in a variety of materials, including insulation, plastics, adhesives, coatings, and even in food additives. Common uses include fire protection and smoke suppression in buildings, and flame retardant in furniture and fabrics.

When rubber is exposed to ammonium metaphosphate, it can cause cracking, swelling, hardening, and discoloration. The chemical reaction between the rubber and the ammonium metaphosphate can cause the rubber to become brittle, which can lead to stress cracks, tears, and other types of damage. Additionally, the ammonium metaphosphate can cause the rubber to become discolored, which can lead to an unappealing look and may also reduce the overall performance of the rubber.
