Resin impregnated felt tube that can be either installed by the inversion method<br />
or pulled into place. The felt tube is made by Inliner Products, Inc (subsidiary)<br />
and sized to fit the host pipe, taking any bends and diameter transitions into<br />
consideration. Resin impregnation is usually done <strong>of</strong>f-site in a controlled<br />
environment. The catalyzed resin impregnated tube can be stored <strong>for</strong> up to two<br />
weeks in a refrigerated environment. Isophthalic polyester, vinylester and epoxy<br />
resin systems can be accommodated. Inliner CIPP incorporates two patented<br />
features: StretchGuard and ResinGuard<br />
• No dig or limited excavation renewal<br />
• 40% to 50% less costly than traditional open cut replacement<br />
• Minimum 50 year service life<br />
• No long-term pressure regression or tensile testing has been done<br />

Materials <strong>of</strong><br />
Inliner Technologies uses both isophthalic polyester resin, epoxy vinyl ester and<br />
Composition<br />
“enhanced” polyesters. The enhanced resin is a filled isophthalic polyester.<br />
Inliner fills their isophthalic polyester resin with a variety <strong>of</strong> materials based on<br />
the application. The non-woven needled felt tube is made <strong>of</strong> polyester fibers. An<br />
outer layer <strong>of</strong> impermeable thermoplastic material (polyethylene or<br />
polyurethane) is used to protect the resin from water and contaminants. If using<br />
the pulled in place installation method, an inner calibration hose or removable<br />
bladder is used. The calibration hose is constructed <strong>of</strong> thin dry felt coated with<br />
an impermeable plastic membrane. The felt is saturated with excess resin in the<br />
