Masterbatch Formulation and Formation
A masterbatch may include a syndiotactic polypropylene and one or more additives. The one or more additives may be present in the masterbatch in an amount of at least 13 weight percent based on a total weight of the masterbatch. The masterbatch may be formed by mixing the one or more additives with the syndiotactic polypropylene. The masterbatch may be mixed with a resin to form a resin mixture.
FIBER-REIMFORCED MOLDED BODIES MADE OF EXPANDED PARTICLE FOAM MATERIAL
The present invention relates to a molding made of expanded bead foam, wherein at least one fiber (F) is partly within the molding, i.e. is surrounded by the expanded bead foam. The two ends of the respective fibers (F) that are not surrounded by the expanded bead foam thus each project from one side of the corresponding molding. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings of the invention from expanded bead foam or the panels of the invention and for the use thereof, for example as rotor blade in wind turbines.
A PROCESS FOR PREPARING FREE-STANDING FILMS OF CONDUCTIVE POLYMERS
The present invention relates to a process for the preparation of films of conductive polymers, by the technique so-called roll-to-roll, which allows to obtain freestanding films having advantageous features such as toughness, flexibility, ability to adhere to different substrates, a submicron thickness and a very high ratio surface area/thickness; the present films are suitable for use in several technological applications, in particular for the development of biosensors, and in the production of flexible electronic components with large surface, suitable for wearable devices and also intended for contacting skin.
PROCESSING AID AND BLEND EMPLOYING THE PROCESSING AID FOR ACHIEVING EFFECTIVE ORIENTATION OF AN EXTRUDED FILM LAYER AND A BIAXIALLY ORIENTED FILM INCLUDING SUCH FILM LAYER
