摘要: Pavement-marking sheet materials of increased durability comprise a tough, abrasion-resistant top layer, preferably a polyurethane film having substantial flexibility but including trifunctional hydroxyl-terminated components of short molecular weight so as to obtain a significant degree of crosslinking, and a conformable underlying layer. A preferred underlying layer comprises unvulcanized elastomer precursor.

摘要: Pavement-marking sheet material which comprises a non-crosslinked elastomeric precursor such as acrylonitrile-butadiene polymer; a thermoplastic polymer such as polyethylene which reinforces the sheet material, e.g., by orientation of the thermoplastic polymer so that the calendered product exhibits greater tensile strength downweb than crossweb; and a particulate inorganic filler, which preferably includes platelet-type fillers such as talc, mica, or magnesium silicate.
