Fluoropolymer blend
The present invention relates to the preparation of a thermoplastic fluoropolymer blend composition exhibiting improved mechanical properties upon fabrication. The fluoropolymer blend composite on is produced by blending an emulsion latex of fluoropolymer (A) with an emulsion latex of fluorinated copolymer (B). Copolymer (B) emulsion has a small particle size, super high MW, and a low degree of crystallinity. The blending of the latex emulsions results in a morphology with small particles of copolymer (B) uniformly distributed within a matrix of fluoropolymer (A) in a manner that could not be achieved by a mere melt blending of the tow components.

System and method for cutting material in continuous fiber reinforced additive manufacturing
Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.
Twin-screw dry granulation for producing solid formulations
A dry granulation process using a twin-screw extruder for granulating a powder mixture which includes at least one active ingredient and at least one carrier. The process includes steps of kneading the powder mixture in the screw barrel of the twin-screw extruder at a barrel temperature below a melting point of the at least one active ingredient and a melting point or a glass transition temperature of the at least one carrier to provide a kneaded powder mixture, and extruding the kneaded powder mixture to form granules. Granules and tablets produced using the dry granulation process in the twin-screw extruder are also provided.
Extruding nozzle, system, and method therefor
A method for pelletizing an extruded material with an extruding nozzle includes inserting the extruded material into the extruding nozzle so that the extruded material flows through at least one material-flow channel, extending through a radiator of the extruding nozzle. Heat is transferred between the extruded material, flowing through the at least one material-flow channel, and the radiator. At least a portion of the radiator is located within a housing of the extruding nozzle.
ACRYLIC RESIN FILM AND PRODUCTION METHOD THEREFOR
A resin film comprising a multilayer structure acrylic polymer and the film having an acid value of not more than 0.018 mmol/g in an acetone insoluble matter, an acid value of not more than 0.012 mmol/g in an acetone soluble matter, a glass transition temperature of not less than 80° C. and a thickness of 5 to 300 μm is obtained by a method comprising emulsion polymerization for producing a latex comprising multilayer structure acrylic polymer, coagulating the latex comprising the multilayer structure acrylic polymer to obtain a slurry, washing and dehydrating the slurry, drying the dehydrated slurry to remove the multilayer structure acrylic polymer, mixing 0 to 35% by mass of an acrylic resin and 65 to 100% by mass of the removed multilayer structure acrylic polymer and subjecting the resultant mixture melted to an extrusion molding.
PROCESS FOR PRODUCING POLYMERS IN POWDER FORM
The present invention relates to a process for producing polymers in powder form by using laser energy. It relates also to polymers in powder form obtainable according to that process, and the use of those polymers in powder form in additive manufacturing.
Polypropylene Particles, Preparation Method Therefor, Bipolar Plate Manufactured Using Same, and Redox Flow Battery Comprising Same
The present invention relates to polypropylene particles and a method for preparing same, the polypropylene particles being formed from a polypropylene resin, and having a melting index (M.I.) of 1000 g/10 min or more when the particles are re-melted under a temperature condition of 150° C. to 250° C. and a condition of atmospheric pressure to a pressure of 15 MPa.
GRANULATOR DEVICE WITH MAGNETIC COUPLING
Apparatus for cutting off extrudate produced with an extruder having a die with at least one opening includes a knife which is mounted rotatably about an axis of rotation and which can be driven by a drive, in particular an electric motor, in that a torque is transmitted from the drive to the knife. A bearing element is provided which can be rigidly connected to the extruder and via which the knife can be rotatably connected to the extruder around the axis of rotation, whereby the drive can be placed separately from the bearing element and a magnetic coupling is provided between the bearing element and the drive in order to transmit the torque from the drive to the knife via magnetic forces.
PELLET PRODUCTION METHOD
A pellet production method comprising: an operation in which a strand comprising a glass-fiber-reinforced polyamide resin composition containing 50 mass % to 80 mass % of glass fiber is extruded from an orifice at a die; an operation in which the strand is drawn into water within a tank and is cooled; and an operation in which the cooled strand is cut to obtain a pellet; wherein an angle of incidence at which the strand enters the water within the tank is not less than 70° but is less than 90°; and wherein a ratio of a diameter of the pellet to a diameter of the orifice (diameter of the pellet/diameter of the orifice) is 0.65 to 0.97.
