1.What is wet-laid fiberglass nonwoven fabric?

It is an innovative industrial material produced by processing electronic-grade chopped fiberglass strands using a specialized wet-laid process. This unique manufacturing method endows it with a range of exceptional physical and chemical properties, serving as a critical foundation for high-performance composite materials.

Wet-laid Fiberglass Nonwoven Core Materials

• Alkali free Chopped Glass Fiber (E-Glass): Serves as the "skeleton," providing high strength and excellent chemical stability.

• Specialized Adhesive: Acts as the "binder," tightly bonding the fibers together to impart flexibility and overall structural integrity to the material.

Wet-laid Fiberglass Nonwoven Core Process: Wet Forming

Simulating the principles of papermaking, this process ensures the random and uniform distribution of fibers within a three dimensional space. This endows the final product with distinct advantages, such as a smooth surface, uniform pore size distribution, and stable air permeability.

2.Wet-laid Fiberglass Nonwoven Environmental Applications: Zeolite / Desiccant Rotor Support Substrates

In zeolite rotor and desiccant rotor systems, glass fiber paper serves as the core structural support material; it not only provides a substrate for the adsorbent to adhere to but also directly determines the rotor's overall structural integrity, heat exchange efficiency, and service life.

Zeolite Rotor（glass fiber paper）

Featuring high temperature resistance and resistance to acid-base corrosion, the glass fiber paper framework ensures the stability of the zeolite adsorbent during high temperature desorption cycles and prolonged operation, effectively capturing and decomposing volatile organic compounds (VOCs) present in industrial exhaust gases.

Desiccant Rotor（glass fiber paper）

With its high air permeability and exceptional dimensional stability, glass fiber paper serves as an ideal carrier for moisture absorbing agents (such as silica gel or molecular sieves), delivering efficient and long lasting dehumidification capabilities in applications requiring low-dew-point air processing particularly in precision manufacturing sectors such as lithium-ion battery production and electronics.

Catalyst Substrate（glass fiber paper）

In industrial waste gas treatment systems such as those utilizing VOC catalytic combustion the performance of the catalyst substrate directly determines purification efficiency.

Thanks to its unique microstructure, glass fiber paper not only effectively supports and anchors the active components of the catalyst but also provides an ample specific surface area for reactions, thereby ensuring thorough contact between the waste gas and the catalyst.
