Basalt fiber chopped strand mat (CSM) is a non-woven material comprised of basalt fibers bonded with an organic binder. It exhibits better mechanical properties, higher temperature tolerance, and greater chemical stability compared to fiberglass CSM. Eco-friendly and more durable, basalt CSM is ideal for high-performance applications in automotive, construction, and marine sectors. Its resistance to corrosion makes it superior to fiberglass mats in highly corrosive environments.
