ABSTRACT:
An article that may be employed to protect a substrate by wrapping the article around the substrate. The article comprises a flexible matrix which is composed of a first material and comprises a plurality of open interstices, the interstices having an average volume of less than 0.01 inch.sup.3 ; and an impregnant which is composed of a second material which has a cone penetration value of 100 to 350 (10.sup.-1 mm) and an ultimate elongation of at least 200%, and comprises a plurality of interconnected segments which lie within the interstices of the matrix. The matrix and the impregnant are such that, when the article is stretched, the matrix reaches its ultimate elongation before the impregnant reaches its ultimate elongation.
