  • Polyimide Film
    Publication number: 20090069532
    Abstract: Disclosed herein is a polyimide film having an elongation from 50 to 150%, a tensile elastic modulus from 4 to 8 GPa, a tensile strength from 150 to 500 MPa, and a hygroscopicity of 5% or less. The polyimide film has high elastic modulus and tensile strength and an excellent elongation, and thus the polyimide film exhibits excellent material properties when it is used as a base film for TAB and COF, and its properties can be usefully modified using an additive to improve productivity and processibility thereof.

  • Intermediate Transfer Belt and Manufacturing Method Thereof
    Publication number: 20090054576
    Abstract: Disclosed are an intermediate transfer belt for use in a laser printer, a fax machine and a copier, and a production method thereof. Specifically, an intermediate transfer belt including silicone modified polyimide resin and a production method thereof are provided, thereby realizing a monolayer intermediate transfer belt having excellent electrical properties, water repellency and heat dissipation properties and good mechanical strength. Further, even without the additional use of an adhesive layer for adhesion to a fluorine resin layer and fluorine resin, the intermediate transfer belt can exhibit satisfactory properties, and process efficiency can be maximized.
