P84 High Temperature Dust Filter Media
Made with imported polyimide P84 base material, this filter media is specially designed for high-temperature, high-dust and corrosive flue gas conditions. It offers excellent resistance to heat, oxidation, corrosion, dust adhesion and abrasion, helping maintain stable filtration performance in demanding industrial environments.
Product Core Parameters
Temperature Resistance
The filter media supports long-term continuous use at 240℃ and can withstand instant peak temperatures up to 260℃. It is suitable for harsh high-temperature flue gas conditions and will not shrink, deform or become brittle under high heat.
Material Advantages
The imported polyimide P84 base material provides excellent resistance to high temperature, oxidation, corrosion and dust adhesion. Its unique irregular fiber cross-section improves dust capture efficiency.
Stable Physical Properties
With uniform and stable air permeability, the material delivers low filtration resistance, thorough dust cleaning and reduced risk of bag blockage or paste formation.
