Description

Fiberglass needle-punched felt is a high-temperature resistant, high-performance filter material made from alkali-free glass fiber through surface chemical treatment. It not only possesses the inherent high-temperature resistance, corrosion resistance, low shrinkage, and high strength of glass fiber, but also features a single-fiber, three-dimensional microporous structure with high porosity and low gas filtration resistance. Its unique felt layer structure achieves a combination of high-efficiency filtration and low resistance, making it suitable for various high-temperature filtration applications.

Features of Fiberglass Needle Felt

  • Temperature resistance

Glass fiber has high temperature resistance, so it can maintain stable performance in high temperature environment and is suitable for high temperature working conditions.

  • Chemically stable

It is inert to many chemical substances and not susceptible to corrosion, so it is suitable for handling various chemical liquids and gases.

  • Mechanical strength

Needle-punching process can form a strong mechanical connection between the fiber layers of the glass fiber felt, which improves the mechanical strength and durability of the filter felt.

  • Microfiltration

The diameter of the glass fiber is finer, which can produce a filter mat with a denser fiber structure, thereby achieving a more efficient microfiltration effect.

  • Adsorption performance

Due to the microstructure of the fiber surface, it has a certain adsorption capacity and can be used in some occasions that need to remove suspended particles and particles.

Upgraded Processing of Fiberglass Needle Felt

To meet the ever-changing industry demands, fiberglass needle felt can be enhanced through various upgraded processing methods to improve its performance.

01. PTFE Membrane Coated Fiberglass Felt

PTFE membrane coated fiberglass needle felt is made by applying a layer of polytetrafluoroethylene (PTFE) membrane on the surface of fiberglass needle felt to enhance its performance in high-temperature and highly corrosive gas environments. PTFE is a material with extremely high thermal resistance and chemical stability. Its excellent non-stick properties and extremely low friction coefficient allow this material to maintain outstanding filtration performance even under extreme working conditions.

02. Fiberglass Blended Needle Felt

Fiberglass blended needle felt is a composite material made by blending fiberglass with other types of fibers, such as polyester, aramid, or polypropylene. This material combines the advantages of different fibers, allowing the performance to be customized according to different application needs, thereby adapting to a wider range of usage scenarios.


Applications

Fiberglass needle felt is widely used across various industries due to its outstanding high-temperature resistance, strength, and filtration performance.

  • Industrial Filtration

Fiberglass needle felt excels in industrial filtration, particularly for high-temperature gas filtration. It is widely used in furnaces, kilns, and other equipment in industries such as steel, cement, and chemicals, where it effectively filters dust particles from high-temperature flue gases, reducing environmental pollution.

  • Automotive Industry

In the automotive sector, it is used in engine air filters, oil filters, and other components. With its high strength and excellent filtration performance, it effectively removes impurities from the air and contaminants from the oil, ensuring stable engine operation and extending its service life.

  • Construction Industry

As an insulation and heat-resistant material, it is applied in the walls, roofs, and other parts of buildings. The air cavities formed within its fiber structure help reduce heat transfer, thereby lowering energy consumption and improving building energy efficiency.

  • Electronics and Electrical Industry

It is used for thermal insulation and electrical insulation in the electronics and electrical industry. Its excellent insulation properties and high-temperature resistance ensure the safe operation of electronic devices under stable temperature and electrical conditions.

  • Aerospace and Marine Applications

Due to its lightweight, high strength, and heat resistance, it is also widely used in aerospace and marine applications. For example, it is used for thermal insulation in aircraft engines and pipe insulation in ships, ensuring the stability and durability of equipment in high-temperature environments.
