Abstract
Disclosed is a base inliner comprising a textile sheet material and a reinforcement, wherein said reinforcement absorbs a force so that, in a stress-strain diagram (at 20.degree. C.), the load at an elongation within the range between 0 and 1% differs by at least 10% at at least one location for said base inliner with said reinforcement compared with said base inliner without said reinforcement, preferably by at least 20%, particularly preferably by at least 30%. The base inliner is useful for producing optionally bituminized roofing and sealing membranes.
Claims20
A base inliner comprising a textile sheet material and a reinforcement in the form of multifilament reinforcing threads wherein said reinforcement absorbs a force so that an applied load needed to generate an elongation of the base inliner within the range between 0 and 1% is at least 10% greater than an applied load needed to generate the same elongation of said base inliner without said reinforcement at at least one value of elongation within the range of 0 to 1%.
A base inliner comprising a textile sheet material and a reinforcement in the form of multifilament reinforcing threads wherein the ratio of the load at a stated elongation, measured at at least one point within the range between 0 and 1%, for said inliner at room temperature (20.degree. C.) to said base inliner at 180.degree. C. is not more than 3.
