DESCRIPTION
Dat Tin, with experience in consulting, processing, and manufacturing, offers the best heat-resistant dust filter bags to clients. Because of the importance of the application, the Nomex dust filter bag is always valued by us.
Nomex dust filter bag (Nomex bag, Nomex filter bag), also known as Meta Aramide, is a heat-resistant dust filter material produced of Gutsche – Germany substance that can function continuously at 200oC.
Nomex is the name of a material created and manufactured in the 1960s by Dupont in the United States. Today, it is most often known as Meta Aramide. The microscope image clearly shows that it has a pretty unique form and a huge surface area, allowing it to filter very tiny particles.
Outstanding features of the Nomex filter bag
- Strengths: Nomex material dust filter bag has strong points of high-temperature resistance, can be up to 220 degrees, good abrasion resistance, anti-adhesion.
- Weaknesses: Nomex dust filter bags are easily hydrolyzed, easily rotted by acid vapors. It is therefore only suitable for certain applications.
Specifications of Nomex dust filter bag
The surface is hot-rolled and burned, in addition to moisture-proof, oil-proof, and PTFE lamination as required by each application.
