Better Products,Better Protect and Better Life
Fiberglass needle-punched felt utilizes inorganic E-type glass fiber as its primary material, with its main chemical composition consisting of silica and alumina. All products undergo stringent comprehensive inspections and systematic quality control measures to ensure consistent performance, providing customers with a safe and continuous production guarantee. This product is manufactured through a specialized needle-punching process applied to ultra. fine E-type glass fibers. This mechanical interlocking creates a microporous structure within the fiber matrix, endowing the material with exceptional thermal insulation and superior acoustic absorption properties.

Product Features

As a non-toxic inorganic material, it demonstrates significant advantages compared to traditional centrifugal glass wool and asbestos products:

Contains no binding agents or volatile compounds

Free from carcinogenic substances

Exhibits outstanding heat resistance (withstands temperatures up to 700 °C, four times

higher than centrifugal glass wool)

Excellent tensile strength and flexibility

Superior fire resistance and corrosion resistance

Remarkable electrical insulation properties

Easy workability for cutting and shaping

The material's unique combination of characteristics makes it an innovative, eco-friendly solution in thermal and acousticinsulation applications.

Technical advantages:

Continuous service temperature: -60° C to +700°C

Density range: 80-150 kg/m:(customizable)

Fiber diameter: 3-6 um(E-glass specification)

Non-combustible (ASTM E84 Class A rating)

Chemical stability(pH resistance: 2-12)

Sizes
Application

1. Construction & HVAC:

When resin-impregnated and formed into boards, serves as effective thermal-acoustic insulation for building structures and air conditioner linings

Surface-laminated with aluminum foil, plastic film, or fiberglass cloth for enhanced performance

2.industrialinsulation:

Processed into strip form for pipeline insulation (both aboveground and underground)

Generator set insulation with superior noise reduction

Effective insulation for color-coated steel roofing systems

3. Acoustic engineering:

Widely implemented in muffler cores due to:

High porosity structure (typically 85-95%)

Excellent sound absorption coefficients (NRC 0.8-1.0 across broad frequency ranges)

Low thermal conductivity (0.032-0.040 W/m· K at 25° C)

4.Automotive engineering:

Globally adopted in automotive/motorcycle exhaust systems for:

Noise attenuation through optimized acoustic impedance

Thermal management enabling complete catalytic conversion (achieving >95% HC/CO/NOx reduction in modern catalytic converters)

Corrosion resistance in harsh exhaust environments (pH 2-12, temperatures 400-700°C)
