Asbestos cloth coated with good quality resilient rubber proofing
is available in the continuous sheet form as well as folded tape
form. Proofed sheeting and tapes, due to good flow characteristics
are excellent sealing materials particularly where the flange
surfaces are not machined and uniform. Proofed goods are expected
to yield under minor pressures to conform to uneven and rough
surfaces to offer a perfect seal. Further the proofed goods used
under high temperature conditions allow the rubber compound to
vulcunise and provide a hard joint for efficient sealing.
