What are the common application areas of ordinary electronic cloth and fiberglass mat?

Fiberglass felt is formed using a wet-process method with chopped glass fibers. It has a loose structure, good air permeability, and strong absorbency, providing excellent impermeability, sound insulation, and corrosion resistance.

Fiberglass electronic cloth is a high-density fabric made from alkali-free glass fiber through weaving and surface treatment. It features high strength, low dielectric constant, and strong dimensional stability.

Although their forming processes and physical structures differ significantly, their core substrate properties are consistent. They are highly compatible in applications requiring insulation protection, weather resistance, and structural reinforcement, covering a wide range of mainstream industrial products and new material products.

1. In the core field of electronic and electrical insulation, these two materials have the highest degree of overlap in application. In traditional insulation boards, composite insulation partitions, and electrical equipment insulation pads, fiberglass electronic cloth is often used as a skeleton substrate, combined with resin impregnation to create rigid insulation components, ensuring the structural strength and electrical stability of equipment during long-term operation. Fiberglass felt, on the other hand, is mostly used for insulation layer wrapping, gap filling, and soft insulation pads. Its dense fiber structure enhances the sealing and breakdown resistance of the insulation layer. In addition, the outer protective layers of high and low voltage switchgear, transformers, and motor windings will use two materials as needed to adapt to different processing requirements of flexibility and hardness, becoming the basic materials for the safety protection of electrical equipment.

2. In the new energy industry, two fiberglass materials are widely used in energy storage, photovoltaic, and lithium battery supporting products. The backsheet substrate and frame sealing protective layer of photovoltaic modules require aging-resistant, UV-resistant, waterproof, and moisture-proof fiberglass substrates. Electronic cloth composite resin can be used to make high-strength backsheet reinforcement layers, while thin felt is used for edge sealing, buffer protection, and waterproof coating substrates. In the heat insulation and fireproof partitions of lithium battery modules and the protective plates of energy storage cabinets, the flame-retardant and temperature-resistant properties of alkali-free fiberglass are fully utilized. Electronic cloth is used for structural reinforcement, and fiberglass thin felt is used for heat insulation, buffering, and fireproof coating. This dual combination improves the safety factor of new energy equipment and is also a key material selection for the current lightweight transformation of the energy storage industry.

3. In key application scenarios where both materials are used in corrosion protection and chemical composite materials, corrosion-resistant products such as chemical pipelines, storage tanks, sewage treatment equipment, and anti-corrosion flooring are exposed to acidic and alkaline corrosive media for extended periods, requiring extremely high corrosion resistance and leak-proof properties of the substrate. Fiberglass felt, with its fine fibers and strong coverage, is the preferred material for corrosion-resistant linings and leak-proof surfaces, effectively blocking the penetration of corrosive media. Electro-woven fabric, with its higher mechanical strength, serves as a middle-layer reinforcing substrate, improving the overall tensile and compressive strength of corrosion-resistant products. In fiberglass products, integrated corrosion-resistant tanks, and municipal sewage pipes, the composite structure of felt + electro-woven fabric is already a common industry solution, balancing corrosion and leak-proof properties with structural durability.

4. In the rail transit and industrial lightweight components sectors, the application of both materials is further expanding. Products such as train interior panels, sound and heat insulation wall panels, equipment shells, and industrial lightweight enclosures need to simultaneously meet the requirements of flame retardancy, sound insulation, heat insulation, lightweight, and high strength. Fiberglass electronic cloth, after being impregnated with resin, exhibits good formability and high strength, making it suitable for manufacturing rigid structural components. Fiberglass felt possesses excellent sound absorption, heat insulation, and vibration damping properties, and is widely used in interior linings, sound insulation filling, and surface protective layers. The combination of these two materials controls product weight while improving the safety and comfort of the equipment's operating environment, making them widely applicable to components for rail transit and industrial automation equipment.

5. Both materials are also found in the fields of building energy conservation and fireproof decoration. Fire-retardant wall panels, ceiling substrates, pipe insulation and protection layers, and building waterproofing reinforcement layers utilize the non-combustible, temperature-resistant, and crack-resistant properties of fiberglass for stable performance. Electronic cloth is often used in fireproof board reinforcement layers and wall crack-resistant mesh substrates to improve the crack resistance and impact resistance of building materials; fiberglass felt is suitable for wall cladding, insulation pipe cladding, and fireproof facing substrates, offering better breathability and adhesion, and meeting the diverse needs of building decoration and engineering infrastructure.

Comprehensive analysis shows that fiberglass mat and fiberglass electronic cloth are not independent competitors, but rather complementary and symbiotic supporting materials. From electronics and electrical engineering, new energy storage, to chemical corrosion protection, rail transportation, and building fire protection, their multiple shared application scenarios demonstrate the irreplaceable role of fiberglass materials in modern industry.

In actual material selection, enterprises can flexibly combine materials based on product hardness requirements, structural strength, corrosion resistance levels, and production costs: fiberglass electronic cloth is chosen for high strength and low dielectric constant; fiberglass mat is prioritized for its anti-seepage sealing, sound insulation, heat insulation, and flexible covering properties; high-end composite products adopt a double-layer composite structure to maximize the comprehensive performance of both materials. In the future, with the iteration of new material technologies, the shared application scenarios of these two fiberglass materials will continue to expand, becoming an important foundational support for the upgrading of various industries.
