AI Technical Summary

Benefits of technology

The sheet effectively isolates aircraft components from moisture and humidity, preventing corrosion and allowing for efficient maintenance by ensuring easy peeling and re-adhesion without property degradation.

Problems solved by technology

Also, in an adhering work of an adhesive tape to a floor panel, a constructional material etc., it is not always easy to adhere an adhesive tape in a uniform manner to desired part of a floor panel (or constructional material) without enclosing air between the tape and the floor panel (or constructional material), and re-adhering (once peeling and adhering again) is often performed.

Abstract

The present invention provides a sheet having an elastomer layer having a Shore A hardness of less than 40, wherein the elastomer layer has an adhesion force to stainless steel of not more than 11 oz / in at 90 degree peel strength.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a novel sheet simultaneously having superior adhesiveness to an adherend and superior re-peel property.BACKGROUND OF THE INVENTION[0002]For example, carpets of various materials and forms are generally laid on the floor panel of aircrafts for the purpose of walking ease, beauty, heat-retaining property and the like. On the other hand, since electrical components, electric wiring and the like are set under the floor panel, it is necessary to shut off the moisture and humidity from the floor panel so that the moisture will not penetrate under the floor panel. The airframe constructional material under a floor panel (hereinafter to be also simply abbreviated as “constructional material”) cannot be easily exchanged during maintenance, and corrosion needs to be prevented even when moisture penetrates under the floor panel. Particularly, since floor panel and airframe constructional material of aircraft cargo room are ...
