  • Publication number: 20150111013
    Abstract: Provided is an a aramid-resin film laminate comprising an aramid paper comprising an aramid fibrid and an aramid short fiber, and a resin film laminated on each other. The aramid-resin film laminate is obtained by conducting a plasma treatment on a surface of the aramid paper, the surface having a skin layer portion whose heat of fusion measured with a differential scanning calorimeter (DSC) is 25 cal/g or less, and bonding the aramid paper and the resin film to each other by heating, pressing, or heating under pressure, with the plasma treated surface of the aramid paper and a plasma treated surface of the resin film facing each other. This laminate is an aramid-resin film laminate in which the aramid paper and the resin film are laminated on each other without using any adhesive agent and without impairing characteristics of both the aramid paper and the resin film, and is excellent in heat resistance, electrical characteristics, chemical resistance, mechanical characteristics, and the like.

  • Patent number: 8999468
    Abstract: A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked. Method for producing the article and for masking the haze are also provided.

  • Publication number: 20120063704
    Abstract: A thermoplastic bag suitable for use as a liner for a garbage canister or trash receptacle may be made from a multi-layered thermoplastic web material. The multi-layer web material may include a first layer and a second layer adjacent to the first layer. Under typical conditions, the layers may tend to block or adhere together to remain in their adjacent position. However, the layers may delaminate and separate from each other when sufficient forces are applied. Delamination of the layers allows the layers to move with respect to each other when the force is applied. The delaminating of the layers absorbs energy which may increase tear and puncture resistance.

  • Patent number: 8133417
    Abstract: Disclosed is a process for the preparation of shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles, having high transparency and low haze comprising immiscible blends of one or more thermoplastic polymers selected from polyesters, polycarbonates, and polyarylates, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about ?0.0006. The small difference in the refractive indices enables the incorporation of regrind into the polymer composition to produce transparent shaped articles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into the compositions to produce shaped articles having oxygen-scavenging properties.
