  • Seam-sealed filters and methods of making thereof
    Patent number: 8790432
    Abstract: A seam-sealed filter in which the seam is sealed with a seam tape comprised of an expanded fluoropolymer, such as ePTFE and copolymers thereof, having a crosswise matrix modulus of greater than 1,950 psi and an enthalpy ratio of less than 0.6 is disclosed. Such seam-sealed filters are capable of undergoing greater than 50,000 pulse-jet or reverse air cleaning cycles without substantial cracking or peeling of the sealed seam. Accordingly, the seam-sealed filters in the form of bags are particularly suitable for use in reducing particulate emissions in cement baghouses and the like.
