Abstract: Disclosed is a coating composition and coated film having the coating composition adhered thereto in which the coating composition comprises particulate filler; binder composition comprising acrylic polymer and ethylene acrylic acid copolymers; non-cross-linking adhesion promoter; and optionally urethane polymer, styrene-acrylic copolymer, or a combination thereof; and wherein cross-linker(s) are substantially absent from the composition; and wherein the coated film has a 45° Gloss (ASTM D2457) of less than 30 or 25 or 20 or 15. The coated film is useful for pressure sensitive labels for thermal transfer ribbon printing labels.

Abstract: A method for producing a high strength, flexible crosslinked polyethylene (PEX) material is provided wherein the base polymer is intermixed with a polymer modifier which affects the amorphous region of the polymer, leaving the crystalline portion of the base polymer virtually unaffected. Consequently, the amorphous region's density is lowered, resulting in a more flexible final product, while the crosslinked molecular structure and/or crystalline portion of the polymer, which controls the strength of the base polymer, remains strong. The polymer modifier can comprise a hydrocarbon fluid such as PAO, Group III basestocks, or a gas-to-liquid hydrocarbon. The plastic material has particular utility in the production of tubing, piping, and conduits for transporting gases, liquids, and the like, as well as wire and cable coatings such as jacketing and insulation.
