Chapel Hill, NC, 5 December 2023 – Armacell, a global leader in flexible foam for the equipment insulation market and a leading provider of engineered foams, announced today the addition of Monarch® 9021 to the ArmaComp™ family of our component foam solutions. Armacell’s sulfur-free* EPDM foam answers the demand from engineers and designers seeking a product free from added sulfur.

From automotive and consumer electronics to outdoor lighting or industrial applications, Monarch 9021 offers an innovative solution to the problem of corrosion due to sulfur outgassing, creep corrosion, and silver surface tarnishing.
