What Is The Function Of Installing A Muffler Heat Insulation Jacket On The Muffler?

Muffler heat shields are used to isolate the heat generated by the muffler and exhaust pipes to prevent it from damaging other components or triggering combustion, while protecting components around the engine, such as plastic and rubber hoses and wires, paint on the surface of the engine compartment and hood, etc.

The muffler heat shield protects against damage caused by localized hot areas of the engine itself. According to the materials used, it plays the role of flame retardant, anti-corrosion, and heat insulation. The heat insulation sleeve of the silencer should have the advantages of small heat transfer coefficient, good heat preservation, moderate weight, easy to roll up, good wind resistance, good waterproofness, and long service life.

The main material components of the muffler heat insulation sleeve:

Glass fiber (temperature resistance 550°), aluminum foil layer (anti-radiation, anti-corrosion, flame retardant, etc.), imported high silica oxygen needle felt (used for inner insulation layer, temperature resistance up to 1260°, silica composition up to 97%), outsourcing recommends the use of aluminum foil packaging, which is an ideal material for mass production.
