Products Description
Product Material Composition
This professional Automotive Muffler Packing Material is made of high-purity alkali-free glass fiber. Adopting premium glass beads and quartz sand as core raw materials, the product is processed through high-temperature melting, high-speed centrifugal spinning, layered laying and curing to form a porous and flexible inorganic fiber sound-absorbing cotton. As the most versatile and mainstream filling material for automotive mufflers, exhaust tail drums and three-way catalytic converters, it is professionally optimized for automotive exhaust working conditions. Different from ordinary building-grade glass wool, this Automotive Muffler Packing Material adopts automotive-grade dust-free spinning technology with fine, pure and impurity-free fibers. It effectively prevents powder falling and pipeline blockage, and perfectly adapts to harsh operating environments including high-speed airflow scouring and alternating high and low temperatures of automotive exhaust systems, serving as a high-performance functional sound absorption and thermal insulation auxiliary material for vehicles.
Core Technical Parameters
Calibrated strictly for automotive exhaust conditions, the parameters fully match the original factory supporting, after-sales maintenance and refitting scenarios of passenger cars and light commercial vehicles:
Continuous Temperature Resistance:
Stable operation at 450℃-600℃ under regular working conditions; instantaneous extreme temperature resistance up to 650℃. No melting, carbonization or blackening under long-term high-temperature exposure, ensuring excellent thermal stability.
Standard Specifications:
Density ranges from 80 to 200kg/m³, conventional thickness 5mm-30mm. Custom rolls, sheets and preformed blocks are available to fit various muffler cavity sizes.
Sound Absorption Performance:
Effectively eliminates high-frequency roaring, turbulent airflow noise, idling noise and acceleration abnormal noise of automotive exhaust within 1000Hz-4000Hz, with a sound absorption coefficient of ≥0.85.
Structural Strength:
Three-dimensional interwoven fiber structure with longitudinal tensile strength ≥80kPa, resisting delamination, powdering and shedding under long-term high-speed exhaust airflow scouring.
Product Features & Advantages
Wide Compatibility:
Suitable for over 95% of household sedans, SUVs and light trucks. It is the preferred filling material for OEM matching, after-sales maintenance and mild exhaust refitting, replacing inferior chemical fiber fillers.
Balanced Noise Reduction Effect:
The porous fiber structure dissipates sound energy layer by layer, reducing high-frequency exhaust noise while retaining a deep and stable exhaust tone. It satisfies both original factory mute standards and mild refitting sound effect demands without noise distortion.
High Temperature & Aging Resistance:
Treated with high-temperature setting and curing technology, it avoids shrinkage, hardening and compaction under long-term high-temperature exhaust conditions, effectively preventing later-stage muffler abnormal noise and noise amplification.
Lightweight & Heat Insulation:
Low thermal conductivity and lightweight structure isolate high-temperature radiation from mufflers, reduce chassis temperature, and protect chassis wiring, rubber parts and paint from high-temperature aging damage.

Thermal Insulation & Protection:
Blocks high-temperature exhaust diffusion, reduces chassis high-temperature damage, and improves vehicle driving safety and component durability.
Vibration Damping:
The flexible fiber buffers exhaust pulse vibration, weakens muffler shell resonance and eliminates exhaust system abnormal noise.
Corrosion Prevention & Pipe Protection:
Isolates water vapor and corrosive media in exhaust gas, reduces internal oxidation and corrosion of mufflers, and extends equipment service life.
