MaxBoard LD 2300 insulating board is a low-density product manufactured to tight dimensional tolerances and an excellent surface finish.

A family of vacuum-formed boards designed to be strong, rigid, self-supporting, and resistant to high velocities, high vibrations, erosive forces, and mechanical stresses.
Our fiber boards are typically used for thermal management and with two fiber grades available, customization options are extensive. We offer standard formulations, sizes, and shapes typically found and required in the market.
Our range comprises of the following fiber grades Refractory Ceramic Fibers (RCF) and Low Biopersistent Fibers (LBP).
