5532113W5000 Sound Absorbing Cotton is a sound insulation and thermal barrier pad installed inside the engine hood of JAC HFC1036 light truck. It absorbs high-frequency mechanical noise generated by engine operation and blocks part of radiant heat transferring to the cab. This aftermarket replacement cotton fixes poor noise reduction, partial shedding and burnt foam issues caused by aging adhesive, water soaking and long-term thermal degradation of original insulation pad. Effective sound absorption lowers engine noise entering the cab and improves driving comfort for light trucks used in frequent stop-and-go urban delivery scenarios.
Product Advantages Adopts multi-layer porous sound-absorbing material with good noise attenuation performance. Reinforced aluminum foil surface reflects radiant heat and prevents direct baking from engine heat. Pre-punched mounting holes match hood buckle positions for firm fixation. Each pad is checked for size, thickness and flame retardant property before shipment, pre-cut contour fits hood inner panel perfectly.
