Techmat has been a mainstay of the BGF product line since its inception in 1994. Techmat is a mechanically bonded (needled) mat with superior insulating properties up to 1200 degrees F. It’s 6 lb/cubic ft. density makes it the ideal thermal and sound insulator for automotive or appliances applications. Techmat has excellent vibration and corrosion resistance in heat-generating mechanical or industrial processing equipment.
