    Abstract: A laser-engraveable flexographic printing precursor or patternable element comprises a laser-engraveable layer having two orthogonal dimensions. This laser-engraveable layer comprises one or more elastomeric resins and non-metallic fibers that are oriented in the laser-engraveable layer predominantly in one of its two orthogonal dimensions. The non-metallic fibers have an average length of at least 0.1 mm and an average diameter of at least 1 ?m. The oriented non-metallic fibers reduce curl and shrinkage in the precursor and improve print quality and press life.

  • Publication number: 20120232210
    Abstract: A dynamically vulcanized alloy containing an elastomer and a thermoplastic resin is prepared by a process wherein supercritical fluid is injected into the thermoplastic elastomeric material as the material is mixed in an extruder. The material is mixed under conditions such that the thermoplastic elastomeric material is dynamically vulcanized wherein the elastomer forms a discontinuous dispersed of small particles in a continuous phase of the thermoplastic resin. The DVA material may then be directly formed into film or sheets by the use of at least one set of rolls located adjacent to the extruder outlet.
