REINFORCED PAVEMENT-MARKING SHEET MATERIAL

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 particualte inorganic filler, which preferably includes platelet-type fillers such as talc, mica, or magnesium silicate.
