High Temperature Needled Mat
High temperature needled mats come in a variety of materials and are low-cost replacements for asbestos mats, ceramic fiber paper, and refractory fiber paper. E glass fiber mat is the most common material due to its dimensional stability and resistance to chemicals, humidity, and temperature. It also conforms with Military Specification MIL-1-16411, ASTM-C-1086-96, and Coast Guard Specification for incombustible materials #164.009 and MIL-I-24244.
Basalt fiber mat is the most environmentally friendly high-temperature mat for both manufacturing and recycling. The operating temperature is higher than E glass and can withstand over 1500 °F for certain periods. Silica fiber mat provides excellent temperature resistance and thermal insulation. It is non-irritating, non-reparable, and can withstand temperatures of 2000 °F, making them a great ceramic free insulation alternative.
Applications include: Industrial furnace insulation, oven insulation, engine insulation, acoustic insulation, electrical insulation
