Thermoseal C-4439

Thermoseal C-4439 is an excellent high-performance material for use in high temperature and high-stress applications. The expanded metal reinforcement is a galvanized low carbon steel insert which makes this material suitable when vibrations are present. This material is manufactured with a combination of fiberglass and aramid and inorganic fibers reinforced with a nitrile binder.
