- Product Introduction
Products Description
Truck exhaust packing material, also known as muffler packing or silencer fiber packing, is the core fill material fitted inside truck mufflers and exhaust after‑treatment assemblies. It operates under real‑world working conditions including high‑temperature exhaust, continuous vehicle vibration and high‑speed gas scouring. It delivers noise absorption, heat insulation and inner‑structure support for heavy‑duty truck exhaust systems.
We are Ningjin Zhiyuan New Materials, the direct manufacturer. We supply this product to exhaust system factories, muffler producers and exhaust modification suppliers. All products are developed according to actual diesel truck operating conditions to match various exhaust structure requirements.
Core Functions
This muffler packing solves common practical issues during truck exhaust operation.
Absorbs sound energy generated by fast‑flowing exhaust gas and metal vibration to reduce exhaust noise output
01
Cuts heat radiation passing through the muffler shell and protects nearby chassis parts from long‑term high‑temperature damage
02
Fills gaps between inner perforated pipes and outer shell, buffers driving vibration and avoids collision of internal muffler components
03
Features good blow‑out resistance to prevent fiber loss from continuous gas scouring
04
Maintains stable silencer performance over the whole service life, reduces muffler packing blow‑out failure
05
Material & Working Performance
We provide two material options: glass fiber and basalt fiber exhaust insulation packing. They are built to cope with temperature fluctuation of diesel truck exhaust systems.
- Glass fiber: for conventional exhaust temperature range
- Basalt fiber: for higher‑temperature working scenarios
01
Keep stable fiber structure after repeated thermal cycles, no melting or powdering under rated working temperature
02
Resist corrosion from exhaust gas, sulfur compounds and residual oil mist
03
Stable bulk density under long‑term road vibration, no structural collapse or large‑scale fiber shedding
04
Even fiber distribution ensures uniform sound absorption and heat insulation across filling area
Application Scope
Our silencer fiber packing covers multiple application scenarios.
Vehicle types:
Light‑duty, medium‑duty and heavy‑duty diesel truck mufflers
Project type:
OEM original supporting production, aftermarket replacement mufflers
Extended equipment:
Construction machinery, generator sets and other diesel equipment with similar working conditions
