- Product Introduction
Products Description
Glass fiber muffler packing (multi-layer noise reduction) is a dedicated sound insulation material tailor-made for cavity filling of various exhaust silencers. It is precision-woven from premium continuous bulked textured glass fiber yarn, with low-temperature meltable binding yarn for shaping and restraint. Exhaust heat generated during equipment operation melts the low-temperature restraining yarn, releasing the inherent high elasticity of the glass fiber yarn and allowing the material to fully expand and fill the entire silencer cavity.Glass fiber muffler packing (multi-layer noise reduction) boasts excellent high temperature resistance. It has a softening point of 880 ℃ and a maximum operating temperature of 720 ℃, making it ideal for high-temperature exhaust conditions. The product features flexible dimensions: standard width is within 1000 mm, and areal weight does not exceed 1500 grams per square meter. Custom processing is supported. It is supplied in rolls up to 20 meters long and conventionally packed in cartons, to meet the silencing and filling needs of different types of equipment.
Working Principle
Thermal Rebound
The built-in low-temperature binding yarn melts when exposed to exhaust heat, releasing the elasticity of glass fiber and enabling the material to stretch and fit the inner space of silencers automatically.
Porous Sound Absorption
Micropores formed by multi-layer weaving block and refract exhaust sound waves, weaken sound energy and gradually eliminate noise.
Full Cavity Filling
It fully fills internal gaps after elastic recovery, eliminating vacant spaces inside silencers and preventing noise penetration to improve overall sound insulation.
Product Structure
Multi-layer Composite Structure
Glass fiber muffler packing (multi-layer noise reduction) adopts a multi-layer composite sound insulation structure. Each layer works in synergy to deliver sound absorption, heat insulation and structural shaping, enabling comprehensive noise reduction performance.
Temperature-controlled Binding:
Special low-temperature binding yarn fixes the shape for easy installation at room temperature and unlocks elasticity under high temperatures.
Dense Weaving
Adopting precision weaving technology, the overall structure is compact and uniform, resisting delamination, damage and deformation during long-term use.
Product Advantages
High Temperature Resistance: Made of high-grade heat-resistant glass fiber, it resists aging, carbonization and failure under prolonged high-temperature conditions.
High-efficiency Noise Reduction: The multi-layer sound insulation and elastic filling structure comprehensively blocks noise and delivers uniform, stable silencing performance for all exhaust scenarios.
Strong Versatility: Flexible shape and customizable sizes allow it to fit exhaust silencers of different models and dimensions.
Easy Installation: The neat shape and good flexibility simplify cutting and filling, making it suitable for mass installation.
Functional Features
Efficient Silencing
It absorbs high-frequency and low-frequency exhaust noise, weakens sound transmission and greatly reduces abnormal exhaust noise from operating equipment.
Thermal Insulation Protection
Glass fiber provides good thermal insulation, blocks high exhaust heat and protects silencer shells and surrounding components.
Stable Operating Performance
It optimizes internal cavity airflow, reduces airflow impact and vibration, and avoids extra noise and equipment wear caused by turbulent flow.
Wear Resistance
With excellent resistance to high temperatures and airflow erosion, it will not wear down or collapse under long-term airflow impact and maintains consistent performance.
Application Scope
Automotive Exhaust
Used for filling exhaust silencers of various motor vehicles to reduce exhaust noise and improve driving comfort.
Industrial Equipment
Applied to exhaust silencing for industrial fans, air compressors, generators and other equipment under high-temperature exhaust conditions.
General Machinery
Suitable for exhaust systems of all kinds of general mechanical equipment to resolve excessive and disordered exhaust noise.
Special Equipment
Customizable for exhaust silencing accessories of special operating equipment to meet noise reduction and heat resistance requirements for special working conditions.
