Compound PTFE needle felt is mixed with other high temperature fibers. Through needling, it is made of high temperature compound felt filter material. This kind of compound filter material filter effects well, cost-effective good and good heat resistance. It’s a new high temperature needle felt filter media, in the long service life under high temperature. PTFE fiber needle felt filter can be used in thermal power plants iron and steel industry, cement, asphalt and wood, and chemical high temperature gas filtration. It Is a very good high temperature filter material.
