Fiberglass Composite Needle Felt Filter Cloth
Fiberglass Composite Needle Felt Filter Cloth is a type of non-woven needled fabric that is made from a combination of fiberglass and other synthetic fibers. It is commonly used in industrial filtration applications to separate solid particles from liquids or gases.
Product Details
Fiberglass Composite Needle Felt Filter Cloth is a specialized filter media designed for high-temperature applications and environments where corrosion resistance and stability are crucial. This type of filter cloth combines fiberglass with other synthetic fibers through a needle-felt process to create a durable and efficient filtration fabric.
The general description indicates that Fiberglass Composite Needle Felt Media is known for its high-temperature resistance, corrosion resistance, dimensional stability, and minimal shrinkage. This makes it suitable for various industrial filtration applications, such as in chemical processing, power generation, and metal processing plants.
The needle-felt construction of this filter media allows for a porous yet strong fabric that can trap particulates effectively while maintaining good airflow. Additionally, the composite nature of the fibers used enhances the overall properties of the filter cloth, such as improving chemical resistance and filtration efficiency.

Fiberglass Composite Needle Felt Filter Cloth possesses several key features that make it suitable for use in demanding industrial filtration applications. Here are some of its notable characteristics:
- High-Temperature Resistance: Fiberglass has the ability to withstand high temperatures, making this type of filter cloth ideal for applications where the filtration process involves elevated temperatures.
- Chemical Resistance: The composite material provides excellent resistance to a wide range of chemicals, including acids and alkalis, which is essential for use in the chemical processing industry and other sectors where exposure to aggressive substances is common.
- Dimensional Stability: The cloth maintains its shape and size under varying temperatures and chemical conditions, ensuring consistent filtration performance over time.
- Low Shrinkage: When subjected to heat, fiberglass composite needle felt does not shrink significantly, which contributes to the durability and longevity of the filter media.
- High Filtration Efficiency: The needle felt process creates a porous material with a high surface area, which allows for effective particle capture and high filtration efficiency.
- Strength and Durability: The combination of fiberglass with synthetic fibers results in a strong material that can withstand continuous use and mechanical stress, including cleaning and maintenance operations.
- Thermal Insulation: Fiberglass has inherent thermal insulating properties, which can be beneficial in applications where heat retention or protection is needed.
- Air Permeability: Despite its ability to capture fine particles, fiberglass composite needle felt allows for good air permeability, which is important for maintaining airflow and reducing resistance in filtration systems.
- Customization: The filter cloth can be customized with different finishes, treatments, or coatings to enhance its properties, such as PTFE (polytetrafluoroethylene) coating for improved dust release or antistatic treatments for applications with combustible dust.
These features make Fiberglass Composite Needle Felt Filter Cloth an effective solution for industrial filtration challenges, especially in environments where durability, efficiency, and performance at high temperatures are required.
