Aramid, which is also referred to as Nomex©, is extensively utilized in high-temperature situations due to its exceptional ability to withstand wear and its capacity to function effectively at temperatures up to 204°C. The aramid filter bag is a filter bag designed for use in pulse jet baghouse dust collectors in high-temperature environments. Aramid is more economical and superior compared to other heat-resistant fabrics. It exhibits excellent strength, resistance to abrasion and folding, and is also resistant to acids.

Features:
• With its exceptional heat resistance, it can maintain excellent performance even in temperatures as high as 204℃ under acidic or alkaline conditions.
• It has excellent resistance to weak acids, weak alkalis, and organic solvents.
• Its impressive thermal stability and minimal contraction ensure that the size of the filter pocket remains stable, preventing any damage to the bag cage.
• The outstanding wear resistance and folding endurance make it ideal for various dust structures and quantities, resulting in a longer service life for the filter material.
• Its high resistance to breakage and elongation ratio ensure that the end product has exceptional strength, durability, and injection tolerance.
• Metamax is easy to process, resulting in minimal waste and compatibility with most machines, improving processing efficiency and reducing costs.
• It offers a perfect balance between performance and price, with a high-performance-to-price ratio.
• Its excellent ventilation performance reduces the pressure drop in the dust removal system, saving energy and related costs.
• It is flame retardant.
